Dongguan Da Ling Shan Chang Sheng processing hardware store aging Zinc Alloy mainly containing Al and Cu solid solution of zinc-rich and Al-rich solid solution containing Zn in the composition, their solubility decreases with the decrease in temperature. However, due to the fast solidification rate of zinc alloy die casting medal supplier, so to room temperature, 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. Dongguan Da Ling Shan Chang Sheng processing hardware store impurity elements: lead, cadmium, tin and zinc alloys become sensitive to intergranular corrosion of zinc alloy medal production, accelerated intergranular corrosion of zinc alloy medal itself in a warm, wet environment products, reduce the mechanical properties, and dimensional changes caused by casting. When zinc alloy impurity elements such as lead, cadmium content is too high, the workpiece just die cast zinc alloy molding, surface quality as usual, but is stored at room temperature for a period of time (eight weeks to a few months), the surface bubbling. Zinc alloy medal supplier, 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.
