What is C22000 Commercial Bronze?
C22000 Commercial Bronze is a high-copper brass alloy designed primarily for cold forming and decorative industrial applications. Due to its high copper content, the alloy exhibits a warm reddish-gold appearance while maintaining better strength and manufacturability than pure copper.
This alloy is commonly used in:
Deep drawn industrial parts
Electrical terminals
Decorative architectural panels
Precision metal stamping
Automotive hardware
Instrument components
Nameplates and industrial trim
The excellent combination of ductility and surface finish makes C22000 brass alloy highly suitable for applications requiring both aesthetics and precision engineering performance.
