C2680 Brass

Features of C2680 Brass

C2680 JIS is a general purpose brass alloy with good ductility, excellent machinability and weldability, and good corrosion resistance, but may be sensitive to corrosion cracking in certain environments.

C2680 has good machinability, ductility and deep drawing properties, is easy to electroplate or paint, and has good corrosion resistance and weldability.
