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 pin EU regulations, mainly for fastening function zinc alloy handle, often used in the manufacture of rivets and other fasteners, the reason is that in addition it has a certain strength and elongation HDMI metal Shell, the most important is that it has a very good construction convenience. Dongguan Da Ling Shan Chang Sheng processing hardware store Caution poor corrosion resistance. When the alloy composition of impurity elements such as lead, cadmium, tin than the standard time, leading to aging and deformation of the casting, the performance of the volume swell, mechanical properties, especially ductility decreased significantly, a long time or even rupture. Lead, tin, cadmium in the zinc alloy solubility is very small, and therefore become concentrated in the grain boundaries and the cathode, aluminum-rich solid solution of an anode, under the water vapor (electrolyte) the presence of conditions to foster intergranular electrochemical corrosion. Casting due to intergranular corrosion and aging. Zinc alloy plate | Chang Sheng Hardware (certified) | zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
