WECOBA® 330
ALUMINIUM BRONZE
WECOBA® 330 is a hard bronze alloy with increased aluminium content. With regard to mechanical properties the alloy is positioned between WECOBA® 290 and WECOBA® 390 while application areas are comparable to those of WECOBA® 390. Improved sliding properties enable finer surface finishes although this is accompanied by a slight reduction in wear resistance due to the lower hardness level.
