Cupral 5M® (CuAl10Ni5Fe4) is a special bronze alloy that combines high strength and toughness with corrosion resistance, integrating mechanical properties at elevated temperatures. It possesses very high tensile and yield strength, as well as hardness combined with toughness. Through a specific heat treatment applied to Cupral 4M®, it achieves superior mechanical properties, which are maintained even at high temperatures. It also exhibits excellent sliding properties.
