More Information
Summary:Copper alloy for plastic-working molds, containing as other principal components aluminum, beryllium, silicon and cobalt, having a value of 9 to 18 weight percent, calculated by an aluminum conversion formula Al + 1.8 percent Be + 1.5 percent Si and 1.5 percent Co, all in weight percent, and containing 6 to 15 percent Al, 0.6 to 2 percent Be, 0.9 to 3.5 percent Si, 0.5 to 2.5 percent Co and the balance Cu, the alloy being characterized by readiness to be used in the as-cast state without being subjected to heat treatment, and having excellent wear resistance under load, as well as high toughness and other desirable mechanical properties. In some cases, the alloy may additionally contain as secondary elements at least one of the elements Sn, Zn, Mn, Fe and Zr. The alloys are particularly suitable for dies in deep drawing, which are required to have high mechanical strength and wear resistance.
