Copper-zinc alloy

Abstract

A copper-zinc alloy includes 56-65%, by weight, of copper (Cu), 0.2-1.5%, by weight, of Tin (Sn) for improving tensile strength of copper (Cu) and for strengthening the corrosion resistance of Zinc (Zn), 0.1-1.0%, by weight, of Aluminum (Al) for ameliorating the yielding and tensile strength and corrosion resistance of the alloy, 0.01-0.6%, by weight, of Nickel (Ni) for improving the yielding and the tensile strength and the resistance and the heat conductivity of the alloy, lower than 0.5%, by weight, of Ferrite (Fe), 0.05-2.0%, by weight, of Antimony (Sb) for strengthen cutting ability and improving corrosion resistance, with the balance being zinc (Zn) and inevitable impurities.
