Abstract

PURPOSE:To improve the mechanical workability, especially the machinability of a wear resistant brass alloy while maintaining the superior wear resistance of the alloy by adding a specified amount of Pb to the alloy contg. Al, Fe, Ni and Zr. CONSTITUTION:This wear resistant brass alloy has a composition consisting of, by weight, 55-70% Cu, 1.0-6.0% Al, 0.1-4.0% Fe, 0.5-5.0% Ni, 0.1-3.0% Zr, 0.1-2.0% Pb and the balance Zn. 0.1-2.0% Si may be incorporated in the composition.
