CoCu

CoCu is a cobalt-copper alloy that combines the high-temperature strength and corrosion resistance of cobalt with copper's thermal and electrical conductivity. This material finds primary use in applications requiring a balance between structural performance at elevated temperatures and efficient heat or electrical transfer, such as aerospace heat exchangers, precision casting applications, and electrical contacts in demanding environments. The alloy is notable for maintaining mechanical integrity in corrosive or thermally cyclic conditions where pure copper would degrade and where traditional cobalt alloys would be unnecessarily expensive or difficult to machine.
