Dongguan Da Ling Shan Chang Sheng processing hardware store control starts with the purchase of alloy composition alloy ingots, alloy ingots must be based on ultra-high-purity zinc-based, with ultra-high-purity aluminum, magnesium, copper alloy ingots formulated to supply plant has strict ingredient standards. Quality zinc alloy material is the production of superior quality cast zinc alloy bearings guarantee. Procuring alloy ingots to ensure that there is a clean, dry stacking area to avoid prolonged exposure to moisture and white rust, dirt or contamination and increase the plant produces slag, metal loss increases. Clean factory environment effective control of the alloy composition is useful effect. Dongguan Da Ling Shan Chang Sheng processing hardware store pressure cast zinc alloy from this alloy after 1940 in the automotive industry zinc alloy medal, production surge in the total consumption of zinc in zinc alloy, about 25% to production of such alloys. The application of advanced technology in the continuous use of zinc alloy products, faster development. Correspondence related to personnel also increased zinc alloy handle, included a full range of iron and 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. Zinc alloy plate, Chang Sheng Hardware (certified), zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
