Abstract

The invention discloses an easy-cutting high strength zinc alloy. Most of current Zn-Al series alloys have the defects of poor cutting performance, inter-granular corrosion tendency, low dimensional stability, low working temperature, poor creep resistance, poor corrosion resistance and the like. The zinc alloy is characterized by comprising the following components in percentage by weight: 1 to 25 percent of aluminum, 0.5 to 3.5 percent of copper, 0.005 to 0.3 percent of magnesium, 0.01 to 0.1 percent of manganese, 0.005 to 0.15 percent of bismuth or / and 0.01 to 0.1 percent of antimony, no more than 0.05 percent of impurities and the balance of zinc. The strength of the zinc alloy can be effectively improved; the zinc alloy has good cutting performance and certain plastic processing performance; the raw materials are cheap, easily obtained and environment-friendly; and the zinc alloy is an ideal material for replacing current domestic lead-containing brass and partial stainless steelparts.

Description

technical field [0001] The invention relates to the field of new alloy materials, in particular to a free-cutting high-strength zinc alloy, which is used to replace lead brass to make electronic and electrical connectors, instrument parts, plumbing and sanitary parts, and automobile and motorcycle spare parts. Background technique [0002] Since the 1920s, with the massive mining and consumption of copper resources, there has been a tense situation of copper resources all over the world. In the face of rising copper prices, our country, which is inherently deficient in copper resources, is imminent in finding copper alloy substitute materials. . Lead brass has excellent cutting performance and wear resistance, and is widely used in electronic and electrical connectors, instrument parts, plumbing and sanitary parts, and automobile and motorcycle parts. However, because lead is contained therein, lead is easy to dissolve, causing environmental pollution and endangering people...
