Beryllium-cobalt-copper is a casting alloy obtained by adding metals beryllium and cobalt to copper. The production process includes vacuum melting, hot forging, solution heat treatment, cold forging, and heat treatment, resulting in a beryllium-cobalt-copper alloy product with high conductivity, thermal conductivity, high hardness, wear resistance, excellent creep resistance, and corrosion resistance. The same as the beryllium-cobalt-copper is an oversaturated solid solution copper-based alloy, which is a non-ferrous metal alloy with excellent mechanical, physical, chemical properties, and good corrosion resistance.
