CuCr1 – UNS.C18200 Chromium Copper is a heat treatable copper alloy
offering good electrical conductivity, resistance to softening at
elevated temperatures and good strength and hardness. This
combination of properties makes C18200 one of the preferred
resistance welding electrode materials for a variety of
applications. Nominally composed of 99.1% copper and 0.9% chromium,
this heat treatable alloy can be brought to its softest condition
by annealing it at 1000°C (1850°F) for one-half hour at
temperature, then rapidly quenching it in water. In this annealed
condition, the alloy is ductile and easily formed, and has an
electrical conductivity of about 40% IACS.
