CuZn15 Brass

Features of CuZn15 Brass

CuZn15 is a solid solution strengthened copper alloy containing 15% zinc (brass). CuZn15 has very good cold formability and is suitable for bending, stamping and other cold forming processes. The alloy can be brazed, brazed or welded. With increasing zinc content, strength increases, but conductivity and ductility decrease. CuZn15 has good resistance to stress corrosion cracking, but if the alloy is exposed to an ammonia atmosphere, it should be stress relieved.
