C18150 Copper Chromium Zirconium

RWMA Class II

Used extensively for cap style resistance welding electrodes. Evidence suggests that it can provide less sticking and resist deformation longer than its copper-chrome counterpart in some specific situations.

Typical Uses for C18150 Copper Chromium Zirconium:

CONSUMER: Pencil-type & Light Soldering Guns: Tips, Rod Extensions

ELECTRICAL: Resistance Welding Electrodes

INDUSTRIAL: Welding Electrodes, Welding Wheels, Tips and Rod Extensions
