Resistance Welding
Resistance Welding Applications
Resistance welding is a joining method in which heat is generated at the interface of workpieces by electrical resistance while mechanical force is applied through copper electrodes. The electrode material plays a critical role: it must conduct high currents efficiently, dissipate heat effectively and maintain mechanical integrity under repeated thermal and mechanical loads. Consumable components made from WECOBA copper alloys are engineered to retain their functional properties over extended operating periods. Improved resistance to softening, wear, and deformation helps maintain stable contact conditions, enabling consistent energy input and reproducible weld quality. For end users, this translates into a more robust process with fewer interruptions and predictable performance.
Wire Mesh Welding
Wire mesh welding is used to join intersecting wires into grids or meshes for construction, reinforcement, fencing, and industrial applications. The process is characterized by extremely high cycle counts and continuous mechanical contact between electrode and wire.
In such environments, electrode wear quickly leads to inconsistent welds and dimensional deviations. WECOBA copper alloys offer enhanced resistance to abrasive wear and surface degradation, allowing electrodes to maintain their geometry and contact quality over long production runs. This stability results in uniform weld nuggets across large mesh areas, reduced scrap rates, and extended maintenance intervals, improving overall line efficiency.
Spot Welding
Spot welding is one of the most widely used resistance welding processes, particularly in sheet metal fabrication, automotive manufacturing, and appliance production. Weld quality depends heavily on the condition of the electrode tips, which are exposed to high temperatures, pressure, and reactive surface coatings.
WECOBA copper alloys are designed to resist thermal softening and mechanical deformation, helping electrode tips retain their shape and functional surface for longer periods. This reduces common issues such as sticking, excessive tip growth, and unstable current transfer. The result is consistent weld strength, fewer corrective interventions, and more predictable production quality.
Seam Welding
Seam welding creates continuous, leak-tight joints using rotating electrode wheels. Typical applications include containers, tanks, pipes, and sealed housings.
The rotating electrodes must combine precise geometry with stable electrical and thermal performance. WECOBA alloys provide the mechanical strength and thermal stability required to minimize wear and distortion of the welding wheels. Consistent electrode geometry supports uniform pressure and current distribution along the seam, resulting in stable weld penetration and reliable seam integrity throughout extended production cycles.
Butt Welding
Butt welding joins components end-to-end by applying electrical current and axial force simultaneously. It is commonly used for wires, rods, tubes, and profiles.
This process subjects electrodes and contact faces to high compressive loads and intense thermal stress. WECOBA copper alloys provide enhanced resistance to plastic deformation under pressure, ensuring stable electrical contact and controlled heat generation at the joint. Improved durability of the welding components contributes to repeatable joint quality and reduces unplanned downtime caused by premature wear.
Projection Welding
Projection welding uses pre-formed projections on one of the workpieces to localize heat generation. It is widely applied for welding fasteners, nuts, studs, and complex stamped parts.
Process reliability depends on precise current concentration and stable electrode surfaces. WECOBA copper alloys help maintain defined contact conditions, ensuring consistent projection collapse and uniform weld formation. Reduced electrode wear improves process stability, particularly in automated and high-volume production, where repeatability is critical.

Wear and Tear
Engineered Materials for Continuous Mechanical Stress and Long Service Life
Wear and tear is one of the most critical limiting factors in industrial equipment and machinery. Components exposed to continuous motion, friction, contact pressure, vibration, or abrasive environments are subject to progressive material degradation that directly affects machine availability, accuracy, and safety. WECOBA alloys developed for wear and tear applications are engineered to withstand these demanding conditions while maintaining stable functional performance over extended operating periods. These materials are specifically designed for components where controlled wear behavior, surface stability, and resistance to mechanical fatigue are essential.
Material Concept for Wear-Dominated Applications
In wear-intensive applications, material performance is defined not by a single property, but by the interaction of hardness, toughness, microstructure stability, and surface behavior. WECOBA alloys for wear and tear applications are optimized to provide:
High resistance to abrasive and adhesive wear
Stable surface integrity under sliding and rolling contact
Resistance to plastic deformation under sustained load
Predictable wear patterns that protect surrounding components
Rather than eliminating wear entirely, WECOBA alloys are engineered to control and slow down wear processes, enabling predictable service life and planned maintenance intervals.
Typical Wear and Tear Applications
WECOBA alloys are used in a wide range of components subjected to continuous mechanical stress, including:
Sliding and guiding elements
Bearings, bushings, and thrust components
Wear plates and sacrificial wear parts
Gears, worm wheels, and transmission elements
Adjustment mechanisms and load-bearing interfaces
Machine components with repeated contact or motion
In these applications, material degradation directly influences machine precision, noise levels, energy efficiency, and risk of failure. WECOBA alloys help maintain functional performance even as components are exposed to long-term operational stress.
Performance Under Continuous Operation
Wear and tear applications are typically characterized by long operating hours, limited maintenance windows, and high reliability requirements. WECOBA alloys are developed to maintain their mechanical properties and surface characteristics under continuous use, reducing the likelihood of premature failure or unexpected downtime.
Enhanced resistance to surface damage and deformation helps components retain their geometry and fit, which is particularly important for precision-guided systems and moving assemblies. This stability supports consistent machine behavior and reduces secondary damage to mating parts
Economic Impact – Managing Wear as a Cost Factor
In many industrial environments, wear-related costs extend far beyond the replacement of individual components. Unplanned downtime, secondary damage, loss of precision, and reduced production output often represent the largest economic impact.
By extending service life and enabling predictable wear behavior, WECOBA alloys help reduce:
Frequency of component replacement
Maintenance labor and intervention effort
Risk of consequential damage to surrounding components
Unplanned production stoppages
This makes WECOBA alloys particularly valuable in applications where availability and reliability are more critical than short-term material cost.

Corrosion
Engineered Materials for Chemically and Environmentally Demanding Conditions
Corrosion is a critical degradation mechanism in many industrial applications, particularly where components are exposed to moisture, aggressive media, temperature fluctuations, or chemically active environments. Corrosion-related damage not only shortens component service life but can also compromise functional reliability, safety, and product quality. WECOBA alloys developed for corrosion resistance applications are engineered to withstand such conditions while maintaining their mechanical integrity and functional performance over extended operating periods. These materials are specifically designed for components where chemical stability, surface protection, and long-term reliability are essential.
Material Concept for Corrosion-Dominated Environments
Corrosion resistance is not solely determined by a single alloying element, but by the overall alloy composition, microstructural stability, and interaction with the operating environment. WECOBA alloys for corrosion-resistant applications are optimized to provide:
Resistance to oxidation and chemical attack
Stable surface behavior in humid or aggressive atmospheres
Reduced susceptibility to pitting, galvanic, and stress corrosion
Preservation of mechanical properties over time
By addressing corrosion at the material level, WECOBA alloys help ensure predictable component behavior even under long-term exposure to challenging environments.
Typical Corrosion Resistance Applications
WECOBA corrosion-resistant alloys are used in a wide range of industrial components, including:
Components exposed to moisture, humidity, or condensation
Parts operating in chemically aggressive atmospheres
Sliding and structural elements in corrosive environments
Cooling and heat transfer components
Machined parts for chemical, process, and marine-related industries
Components in outdoor or temperature-variable installations
In these applications, corrosion can lead to dimensional changes, surface damage, loss of strength, or seizure of moving parts. WECOBA alloys are selected to minimize these risks and maintain reliable functionality.
Long-Term Stability Under Environmental Stress
Corrosion resistance applications are often characterized by continuous or cyclic exposure to aggressive conditions combined with mechanical or thermal loads. WECOBA alloys are developed to maintain surface integrity and internal structure under these combined stresses.
Improved resistance to corrosion-related material degradation helps prevent premature failure and reduces the need for protective coatings or frequent replacement. This contributes to more stable processes and improved operational reliability, especially in systems with limited maintenance access.
Economic Impact – Corrosion as a Lifecycle Cost Driver
Corrosion-related failures rarely affect a single component in isolation. Secondary damage, contamination, unplanned shutdowns, and safety-related interventions often amplify the economic impact.
By extending service life and preserving functional performance, WECOBA corrosion-resistant alloys help reduce:
Frequency of component replacement
Maintenance and inspection effort
Risk of unexpected failure or leakage
Production interruptions due to corrosion-related issues
This makes WECOBA alloys particularly valuable in applications where long-term durability and risk reduction are key economic considerations.
Reliable Performance in Challenging Environments
WECOBA alloys for corrosion resistance are designed to support long service life, stable performance, and predictable maintenance cycles in environments where material degradation cannot be tolerated. Their chemical stability and structural robustness make them a reliable choice for demanding industrial applications across multiple sectors.

Metal Forming
Engineered Materials for Controlled Deformation and Tool Durability
Metal forming processes subject tools and functional components to extreme mechanical loads, surface pressure, and friction. In operations such as deep drawing, tube bending, and tube forming, material flow must be precisely controlled while tool surfaces are exposed to continuous contact with the workpiece. WECOBA alloys developed for metal forming applications are engineered to support stable forming processes by combining high surface durability, controlled friction behavior, and resistance to mechanical deformation. These materials are particularly suited for forming operations involving stainless steel and other demanding materials where tool wear, galling, and surface damage are critical process limitations.
Material Concept for Forming-Dominated Processes
In metal forming, tool performance is defined by the interaction between surface hardness, toughness, microstructural stability, and tribological behavior. WECOBA alloys for metal forming applications are designed to provide:
Resistance to adhesive and abrasive wear
Reduced tendency to galling and material pickup
Stable surface geometry under high contact pressure
Predictable interaction with lubricants and forming media
Rather than relying solely on coatings or surface treatments, WECOBA alloys address forming challenges at the material level, ensuring long-term stability even under repeated forming cycles.
Deep Drawing of Stainless Steel
Deep drawing of stainless steel is one of the most demanding forming processes due to the material’s high strength, work-hardening behavior, and strong tendency to adhere to tool surfaces.
Tool components such as:
Drawing dies
Punches
Blank holders
Guide and support elements
must withstand extreme surface pressure and sliding contact.
WECOBA alloys offer enhanced resistance to galling and surface damage while maintaining dimensional stability under load. Their controlled wear behavior helps preserve tool geometry and surface finish, supporting consistent material flow and reducing the risk of tearing, wrinkling, or surface defects on the formed part. This leads to longer tool life, fewer process interruptions, and more stable production quality.
Tube Bending Applications
Tube bending processes involve localized deformation combined with internal and external friction between tube, mandrel, and bending tools. Stainless steel tubes in particular impose high mechanical and tribological stress on tooling components.
Typical WECOBA applications in tube bending include:
Mandrels
Wiper dies
Pressure dies
Clamp dies
WECOBA alloys provide the mechanical strength and surface durability required to resist deformation and wear during repeated bending cycles. Their stable surface characteristics help minimize scoring, surface marking, and friction-related defects, supporting accurate bend geometry and consistent surface quality of the finished tube.
Tube Forming and Expansion
Tube forming and expansion processes require precise control of material flow while tools are subjected to radial pressure, sliding contact, and cyclic mechanical loads.
WECOBA alloys are used for:
Forming dies
Expansion tools
Calibrating elements
Guide and support components
Their resistance to surface degradation and deformation supports repeatable forming results and reduces tool maintenance requirements. Stable tool geometry helps ensure dimensional accuracy and consistency, particularly in multi-stage forming operations.
Economic Impact – Tool Life and Process Stability
In metal forming operations, tooling performance directly affects production efficiency, scrap rates, and downtime. Tool replacement, reworking, or unplanned stoppages represent significant cost drivers.
By extending tool service life and stabilizing forming conditions, WECOBA alloys help reduce:
Tool change frequency
Process interruptions
Surface-related defects on formed parts
Maintenance and rework effort
This supports lower total cost of ownership and higher overall equipment effectiveness in metal forming operations.

Plastic Injection Moulds
Engineered Materials for Injection Molding Tools and Functional Inserts
Plastics processing, and in particular plastic injection molding, places high demands on mold materials and functional inserts. Mold components are exposed to repeated thermal cycling, mechanical load, and continuous contact with molten polymers, often combined with abrasive fillers, reinforcing fibers, or aggressive additives. WECOBA alloys developed for plastics processing applications are engineered to support stable molding processes by combining thermal performance, mechanical durability, wear resistance, and surface stability. These materials are particularly suited for mold components where dimensional accuracy, reliable movement, and long service life are critical.
Material Concept for Injection Molding Applications
Injection molding tools must maintain precise geometry and surface quality over thousands or millions of cycles. In this environment, material performance is defined by the interaction of thermal conductivity, resistance to wear, dimensional stability, and tribological behavior.
WECOBA alloys for plastics processing applications are designed to provide:
Efficient heat transfer for controlled cooling
Resistance to abrasive and adhesive wear
Stable surface properties under repeated thermal cycling
Reduced sensitivity to deformation and surface damage
By addressing these requirements at the material level, WECOBA alloys help ensure predictable tool behavior and consistent part quality.
Cores
Cores define internal geometries and are directly exposed to molten plastic, pressure, and thermal load. They must retain precise dimensions and surface quality to ensure consistent part geometry and easy demolding.
WECOBA alloys offer stable thermal behavior and resistance to surface degradation, supporting uniform cooling and minimizing the risk of deformation. Improved resistance to wear and surface damage helps maintain dimensional accuracy over long production runs, reducing the need for frequent maintenance or polishing.
Slides and Sliders
Slides and sliders enable the formation of undercuts and complex geometries and are subject to continuous movement, friction, and mechanical load during each molding cycle.
WECOBA alloys provide favorable sliding properties and resistance to wear, helping ensure smooth, reliable movement and accurate positioning. Reduced friction and surface degradation contribute to stable mold operation, minimized risk of sticking or jamming, and extended service life of the moving components.
Additional Typical Mold Inserts
Depending on mold design and application, WECOBA alloys are also used for:
Wear inserts in high-flow areas
Gate and runner inserts
Ejector guide components
Cooling inserts and thermal interfaces
Mold components exposed to abrasive or fiber-reinforced plastics
These inserts benefit from the balanced combination of thermal performance and mechanical durability offered by WECOBA materials.
Economic Impact – Tool Life and Mold Availability
Injection molds represent a significant investment, and unplanned downtime or premature wear of critical inserts can have a major impact on production costs.
By extending service life and ensuring reliable movement and thermal behavior, WECOBA alloys help reduce:
Maintenance and refurbishment frequency
Mold downtime and production interruptions
Risk of dimensional drift or surface defects
Total lifecycle cost of mold components
This makes WECOBA alloys particularly valuable for high-volume production and applications with limited maintenance windows.

Heavy Industry and Steel
Solutions for Extreme Loads, Continuous Operation and Long Service Life
Heavy industry and steel production environments impose some of the most severe operating conditions on mechanical components. Equipment is exposed to high static and dynamic loads, shock, vibration, elevated temperatures, dust, scale, and limited maintenance access. In these conditions, component reliability and predictable wear behavior are essential for safe and efficient operation. WECOBA bronze alloys developed for heavy industry and steel industry applications are engineered to withstand extreme mechanical stress while delivering stable performance over long service intervals. These materials are specifically selected for components where load-bearing capacity, controlled sliding behavior, and resistance to wear and fatigue are critical.
Material Concept for Heavy-Duty Industrial Applications
In heavy industrial environments, material performance is defined by strength under load, toughness, wear resistance, and structural stability. WECOBA bronze alloys are designed to provide:
High load-bearing capability under static and dynamic stress
Resistance to adhesive and abrasive wear
Stable performance under shock, vibration, and misalignment
Predictable wear behavior to protect mating components
Rather than focusing on maximum hardness alone, WECOBA bronze alloys are engineered to achieve a balanced combination of strength and ductility, ensuring reliability even under fluctuating and extreme loads.
Wear Parts and Sacrificial Components
Wear parts in steel plants and heavy machinery are exposed to continuous friction, abrasion, and impact. These components are often designed as sacrificial elements to protect larger and more expensive assemblies.
WECOBA bronze alloys provide controlled wear behavior and resistance to surface damage, helping to extend replacement intervals while protecting adjacent steel components. Typical applications include wear shoes, wear blocks, and contact elements in conveying, forming, and handling equipment.
Sliding Plates
Sliding plates are widely used in steel mills, rolling lines, presses, and heavy transport systems. They must support high loads while allowing controlled movement under difficult lubrication conditions.
WECOBA bronze alloys offer favorable sliding properties and resistance to surface fatigue, enabling smooth motion even under high contact pressure. Their dimensional stability helps maintain alignment and load distribution, reducing the risk of seizure or uneven wear.
Heavily Loaded Bearings and Bushings
Bearings and bushings in heavy industry often operate at low speeds under very high loads, frequently combined with shock loads and vibration.
WECOBA bronze alloys are particularly well suited for such conditions due to their high compressive strength and resistance to plastic deformation. Their tribological properties support reliable operation even with limited or intermittent lubrication, contributing to long service life and reduced risk of catastrophic failure.
Gears and Worm Wheels
Gears and worm wheels in heavy industrial applications are subjected to high contact pressures, continuous sliding, and fluctuating loads.
Bronze alloys are commonly paired with steel counterparts to optimize tribological performance and reduce wear. WECOBA bronze grades offer enhanced resistance to surface fatigue and deformation, supporting smooth torque transmission, reduced noise, and extended service life in gear systems used in steel processing and heavy machinery.
