Features of CuZn10 Brass
CuZn10 Is a solid solution strengthened copper alloy containing 10% zinc (brass). CuZn10 has very good cold formability and is suitable for bending, stamping and other cold forming processes. The alloy can be brazed, brazed or welded. As the zinc content increases, the strength increases, but the conductivity and ductility decrease. CuZn10 has good resistance to stress corrosion cracking, but if the alloy is exposed to an ammonia atmosphere, it should be stress relieved.
