Abstract
The present invention relates to a high-plasticity free-cutting zinc alloy, which includes the following components in percentage of weight: 1-10% Cu, 0.1-3.0% Bi, 0.01-1.5% Mn, 0.001-1% Ti and/or 0.01-0.3% Zr, optional component X, optional component Y, and a remainder component being Zn having less than or equal to 0.01% unavoidable impurities, wherein component X amounts to 0-1.0% and includes at least one element selected from Cr, V, Nb, Ni and Co; and component Y amounts to 0-1.0% and includes at least one element selected from B, As, P and rare earth metal. Compared with existing zinc alloys, the present invention has good machinability, higher plasticity and improved processability, which can be widely used in F connectors, pen manufacturing, socket connectors, locks and etc.
