摘要

Hardenable copper alloy comprises (in wt.%) 1.2-2.7 cobalt, 0.3-0.7 beryllium, 0.01-0.5 zirconium, 0.005-0.2 magnesium and/or iron, optionally up to maximum 0.15 niobium, tantalum, vanadium, hafnium, chromium, manganese, titanium and/or cerium, and a balance of copper. Preferred Features: The copper alloy contains (in wt.%) 1.8-2.4 cobalt, 0.45-0.65 beryllium, 0.15-0.3 zirconium, up to 0.05 magnesium, up to 0.1 iron and a balance of copper. Up to 80% of the cobalt content is replaced by nickel.
