WECOBA® Ni30
COPPER NICKEL ALLOY
Copper–nickel wrought alloys are key materials for applications requiring high corrosion resistance, operational reliability and long-term stability. Within this demanding environment WECOBA® Ni30 is used for applications involving severe operating conditions or continuous exposure to aqueous and corrosive media, particularly where WECOBA® Ni10 reaches its performance limits.

Typical Application
Components with high resistance to corrosion, erosion and cavitation, particularly in shipbuilding and piping systems used in shipbuilding
Drinking water treatment plants, desalination plants
Typical Components
Components for piping systems and plant engineering, particularly in seawater-carrying installations, such as fittings including flanges, valves, connection and joint elements
Plates and tube sheets for heat exchangers and condensers, as well as feedwater preheaters (low pressure), freshwater generators, air conditioning systems, process equipment, finned tubes and brake lines
High-quality alternatives for bolts and nuts, particularly as an upgrade where corrosion-related loads exceed the performance limits of WECOBA® Ni10
