Copper-zinc alloy

Abstract

A copper-zinc alloy includes 56-65%, by weight, of Copper (Cu), 0.2-2.0%, 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), with the balance being Zinc (Zn) and inevitable impurities, the alloy also includes a secondary material, which is Phosphorus (p), Arsenic (As) or both for strengthening the corrosion resistance of the alloy.

1 . A copper-zinc alloy comprising:
 56-65%, by weight, of Copper (Cu),   0.2-2.0%, by weight, of Tin (Sn),   0.1-1.0%, by weight, of Aluminum (Al),   0.01-0.6%, by weight, of Nickel (Ni),   lower than 0.5%, by weight, of Iron (Fe), and   at least one element selected from Phosphorus (P) and Arsenic (As), which are 0.03-0.25%, by weight, of Phosphorus (P), 0.01-0.2%, by weight, of Arsenic (As), combining both materials being no more than 0.35%,   with the balance being Zinc (Zn) and inevitable impurities.
