CHROMZIRC-328

Copper Alloys

CHROMZIRC-328

CHROMZIRC-328 is a copper chromium zirconium alloy with the outstanding electrical and heat transfer properties of copper but without the drawbacks of being soft and ductile.

The addition of a small amount of chromium ensures its high strength, especially after suitable heat treatment that achieves its good mechanical properties.

CHROMZIRC-328 (copper chromium zirconium) is predominantly used in resistance welding equipment and in the field of electrical engineering.
