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.
Chemical Composition of CuCr1-UNS.C18200 Chromium Copper Alloys:
Product Grade: CUBERYLLIUM ®-182 (UNS.C18200)
Cr: 0.60-1.20%
