Cupral 6® is a dual-phase alloy composed of half gamma 2 and half beta phases. The material stands out for its hardness, wear resistance, excellent compression, and sliding characteristics. It exhibits very high wear resistance, offering twice the lifespan compared to standard bearing bronzes. Additionally, it has high chip removal capability. However, due to its low proportional elongation, thin sections should be avoided.
