Dongguan Da Ling Shan Chang Sheng processing hardware store low aluminum and zinc-based alloys generally binary alloys, mainly for anti-corrosion features, basically replacing aluminum with spray galvanizing galvanizing process (new technologies). Aluminum zinc alloy generally ternary alloy of zinc alloy die-casting, mainly for fastening function, often used in the manufacture of rivets and other fasteners, the reason is that in addition it has a certain strength and elongation, the most important is that it has very good construction convenience. Dongguan Da Ling Shan Chang Sheng processing hardware store aging Zinc Alloy mainly containing Al and Cu, Zn-containing zinc-rich solid solution and Al-rich solid solution composed of zinc alloy pins EU regulations, their solubility decreases with temperature drop . However, due to the extremely rapid solidification rate of zinc alloy die casting, so to room temperature zinc alloy handle, the solubility of the solid solution is substantially saturated. After a certain time, this supersaturation will gradually lifted, leaving the shape and size of the casting slightly to change. Zinc alloy electronic hardware, Chang Sheng Hardware (certified), zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
