Chromium copper is a heat treatable corrosion resistant alloy which combines high electrical conductivity with high strength. It is used in applications such as resistance welding electrodes seam welding wheels switch gears cable connectors circuit breaker parts molds spot welding tips and electrical and thermal conductors that require strength.
The structure of slow cooled chromium copper is a two phase mixture of chromium and alpha copper. Switch contacts electric motor and generator components contacts wire high temperature semi conductor bases parts for electronic devices cable connectors thermal conductors requiring greater strength than copper switch gears electrical connectors electrical conductors requiring greater strength than copper arcing and bridging parts circuit breaker parts electron tube grid side rods. 182 copper is stronger harder and more wear resistant than 110 copper. Certificates with a traceable lot number are available for these products.
The age hardening reaction occurs because the solid solubility of chromium in copper decreases as the temperature decreases. Also known as rwma class 2 chromium copper it s commonly used in resistance welding for circuit breaker parts and for molds to make plastic parts.
