C18150 Copper Chromium Zirconium
C18150 Copper Chromium Zirconium is a high-strength, precipitation-hardenable copper alloy with chromium and zirconium additions, known for its excellent electrical conductivity, high thermal stability, and good resistance to softening at elevated temperatures, commonly used in electrical connectors and components that require strength and thermal resistance.
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
