PURPOSE:To produce a special brass alloy having drastically improved corrosion resistance by incorporating specific ratios of Al, Fe, Ni, Si, Pb, Sn and Zn into Cu. CONSTITUTION:The special brass alloy consisting of, by weight, 75-60% Cu, 0.1-3.0% Al, 0.1-1.0% Fe, 0.3-3.0% Ni, 0.1-1.5% Si, 0.2-3.0% Pb, 0.3-2.0% Sn and the balance Zn is prepd. In this way, the special brass alloy having excellent corrosion resistance is obtd. and is useful as valve parts, parts for a pump, etc.
