Dongguan Da Ling Shan Chang Sheng processing hardware store is HDMI metal shell company luggage accessories, zinc alloy and other professional production and processing, and has a complete and scientific quality management system. Integrity, strength and quality of Dongguan Da Ling Shan Chang Sheng processing hardware store by the industry recognition. Welcome friends to visit, guidance and business negotiation. Zinc Alloy classification: 1, cast zinc alloy casting method is divided according to the different pressure cast zinc alloy (under an applied pressure of solidification) and gravity cast zinc alloy (solidification only gravity). 2, this alloy cast zinc alloy pressure from after 1940 in the automotive industry, production surge in the total consumption of zinc, about 25% is used to produce this alloy. The application of advanced technology in the continuous adoption, faster development. Corresponding to the relevant personnel are on the increase, there is a complete collection of the steel network of excellence. The most commonly used alloy system for Zn-Al-Cu-Mg system. Some impurities significantly affect the performance of die-cast zinc alloy. Therefore, restrictions on the content of iron, lead, cadmium, tin and other impurities are very strict, the upper limit is 0.005%, respectively, 0.004%, 0.003%, 0.02%, so the die-cast zinc alloy should be used purity of more than 99.99% of the high-purity zinc as a raw material. 3, gravity casting zinc alloy can be sand, plaster mold or die in the casting. This not only has the characteristics of zinc alloy die-cast zinc alloy zinc alloy general, and high strength, good casting properties, the cooling rate had no significant effect on the mechanical properties of Guangdong zinc alloy jewelry, disability, waste can be recycled, the gate is simple, overheating and remelting insensitive shrinkage zinc alloy products production, less porosity, can be plated using conventional sizing methods. Dongguan Da Ling Shan Chang Sheng processing hardware store zinc alloy, also known as zinc-based alloys, generally divided into binary alloys, ternary alloys and multicomponent alloys. Generally refers to two yuan zinc alloy zinc-aluminum alloy; three yuan zinc base alloys generally refers to copper zinc-aluminum alloy; multi-zinc-aluminum alloy generally refers to copper and other trace metals. Zinc alloy, zinc alloy, zinc-aluminum alloy is a broad concept, does not refer to a specific function of the alloy to meet the concept. Such as zinc-aluminum alloy in accordance with the content of aluminum into low aluminum and zinc based alloys, aluminum and zinc-based alloy high aluminum zinc alloy. Although they are zinc-aluminum alloy, but their performance but has a very different. Dongguan zinc alloy products, Chang Sheng Hardware (certified), zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store. Dongguan Da Ling Shan Chang Sheng processing hardware store (shop1379091614724.1688.com) is Dongguan, hardware accessories leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
