The traditional kind of die-cast zinc alloy with an asterisk 2,3,4,5,7 Shenzhen alloy zinc alloy jewelry, currently the most widely used is the 3rd zinc alloy. Seventies developed high aluminum zinc alloy ZA-8, ZA-12, ZA-27. Zamak 3: good flow and mechanical properties. Applied to the mechanical strength of the less demanding cast zinc alloy, such as toys, lamps, decorations, and some electrical parts. Zamak 5: good mobility and good mechanical properties. Applies to certain requirements on the mechanical strength of the casting, such as auto parts, electrical parts, mechanical parts, electrical components. Zamak 2: for special requirements on the mechanical properties of high hardness, wear resistance, dimensional accuracy requirements of the general mechanical parts. Dongguan City, Daling Shan Chang Sheng processing hardware store early 1970s, Long zinc alloy products, Canada Norand Mines Limied Research Center in collaboration with the United States Zastern company, developed a long-s metal zinc-based anti-friction alloy ZA8, ZA12, ZA27, etc. and anti-friction ZA27 alloy used in rolling mills, presses, gear boxes, mill, air conditioning, precision machine tools and other low-speed, heavy-duty workplace, a comprehensive alternative to the traditional copper-based alloy anti-friction material. A new generation of long-s metal antifriction alloy is greatly concerned about the advent of international customers, many industrialized countries have to invest more human and material resources in the development of long-s metal United States alone, dozens of companies to develop long-s metal aluminum, zinc-based anti-friction alloy series.
