CW507L

 

 

CW507L (CuZn36) is a medium-zinc brass alloy with approx. 36% Zn, offering a balanced combination of strength, ductility, and corrosion resistance. It is ideal for deep drawing, stamping, cold forming, bending, and surface polishing. EN standards provide excellent surface quality and uniform grain structure, making it a preferred alloy in HVAC, electronics, decorative hardware, automotive parts, and industrial engineering.
