CuCrZr is a precipitation-hardened copper alloy with additions of chromium and zirconium. The alloy has a very high electrical and thermal conductivity and good strength. In addition, CuCrZr has a good stress relaxation and the copper alloy retains its strength at high temperatures. As a result, CuCrZr is suitable for complex technical applications requiring high conductivity where parts are exposed to voltages and high temperatures.
