Abstract

A deformable zinc alloy capable of being cold headed. The deformable zinc alloy comprises the following components in percentage by weight: 0.01%≤Cu≤5.0%, 0.01%≤Al≤5.0%, and 0.001%≤Mg≤1.0%, with the balance being Zn and inevitable impurities. The microstructure of the deformable zinc alloy uses a single-phase η-phase solid solution structure as a matrix; the volume fraction of the single-phase η-phase solid solution structure in the microstructure of the deformable zinc alloy is 95-99%. The microstructure of the alloy uses a single-phase η-phase solid solution structure as a matrix, the tensile strength of the alloy can reach 280 MPa or more, and the elongation can reach 15% or more, so that sufficient deformability is provided for cold heading processing.

Description

Technical field [0001] The present invention relates to the technical field of zinc alloy and its application, in particular to a deformed zinc alloy with a single-phase matrix structure. The zinc alloy can be processed by cold heading and other cold deformation, and can be specifically applied to various power plugs, terminal posts and other products . Background technique [0002] Cold heading technology is a kind of high-speed deformation cold processing technology. Metal rods and wires are quickly processed into various complex parts through various molds. Compared with traditional turning technology, cold heading can increase the utilization rate of materials, reduce losses, and improve labor efficiency. The cold heading products have uniform and dense structure and have been widely used in various standard products. Therefore, cold heading has become a metal material processing An important means of molding. [0003] Cold heading has high requirements on the performance of ...
