Lead free brass possess relatively good corrosion resistance, moderately high strength, and in some forms, it has very good ductility. Its hot forms are strong. It also called Muntz metal. It is available mainly in 60/40, 63/37, 65/35 & 70/30 Cu/Zn ratio. A ductile alloy is suitable for blanking, riveting, bending, hot forging & pressing.
