Brass

EN CW510L - UNS C28500

CuZn42 is a copper-zinc alloy belonging to the brass family, containing approximately 42% zinc. It is characterized by its good mechanical strength and ductility, making it particularly well-suited for hot and cold forming operations. This alloy is commonly used in the manufacture of industrial parts, thanks to its good balance between machinability and strength.
