Dongguan Da Ling Shan Chang Sheng processing hardware store Reuters international casting industry, in recent years, China's rapid development of zinc alloy die-casting zinc alloy plate technology, economic benefits and market efficiency should not be underestimated, according to experts, zinc alloy die-casting technology has the following characteristics: a relatively large proportion. 2, zinc alloy die casting process performance is good, you can die casting complex shapes, thin-walled precision castings, smooth surface. 3, may be subjected to surface treatment: electroplating, painting, painting, polishing, grinding and the like. 4, do not smoke when melted and die cast iron, corrosion-pressure, non-stick mold. 5, there is a good room temperature mechanical properties and wear resistance. 6, low melting point, easy casting. 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, resulting in deformation of zinc alloy castings aging occurs, the performance of the volume swell, mechanical properties, especially ductility decreased significantly, a long time or even rupture. Lead, tin, cadmium zinc alloy solubility is very small, and thus become concentrated in the grain boundary and the EU regulation cathode zinc alloy pins, aluminum-rich solid solution becomes anode, water vapor (electrolyte) the presence of conditions to foster inter-Epistar chemical corrosion. Casting due to intergranular corrosion and aging. Zinc alloy die casting | Chang Sheng Hardware (certified) | Hubei zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
