Abstract
A copper/zinc alloy for semi- finished products and semi-manufactured articles, and in particular suitable for synchronising rings, in which a uniform or constant coefficient of friction, good workability and high resistance to wear are required, consists of 70 to 75% Cu, 6 to 8 % Mn, 4 to 6% Al, 1 to 4% Si, 1 to 3% Fe, 0.5 to 1.5% Pb, less than 0.05% Ni, less than 0.05% Sn, the remainder being Zn (all data expressed as percentages by weight). Said alloy has a structure consisting of beta -phase in which 15 to 40%, preferably approximately 30 to 35%, alpha -phase is embedded. A method of producing the alloy comprises the steps of continuous casting, extrusion, forging, rapid cooling from between 600 and 750 DEG C, and subsequent heat treatment at between 1 and 20 hours at 150 to 350 DEG C leading to alpha -precipitation of 15 to 40%.
