This fact sheet focuses exclusively on trivalent 3 chromium. 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.

Chromium copper alloys are designated as uns c18050 through c18600 the cast alloys are c81400 through c81540. 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. Chromated copper arsenate cca treated wood under 29 cfr 1910 1200 hazard communication standard are considered mixtures due to further processing which may produce dusts and or fume. Typical uses for c18200 chromium copper.

The structure of slow cooled chromium copper is a two phase mixture of chromium and alpha copper. Easy to machine 145 copper bars also called tellurium copper 145 copper contains tellurium which makes it more machinable than all other copper while maintaining good corrosion resistance and.
