Dongguan Da Ling Shan Chang Sheng processing hardware store ingredients quality features: zinc alloy die casting performance Which is good and strong, die-cast shapes can be complex, thin-walled precision castings, smooth surface. Can be subjected to surface treatment: electroplating, painting, painting, polishing, grinding and the like. No absorption of iron melting and casting, non-corrosive pressure-type zinc alloy, non-stick mold. Low melting point of zinc alloy jewelry supplies, melting at 385 ℃, easy casting. Dongguan Da Ling Shan Chang Sheng processing hardware store conditional casting plant is best centralized melting furnace zinc alloy, the alloy ingot with a uniform charge ratio back to British regulations zinc alloy pins, flux can be more effective use of the alloy composition and temperature maintain uniformity and stability. Electroplating waste, fines should be a separate furnace. Zinc alloy mainly containing Al and Cu by zinc-rich solid solution and Zn-containing Al-rich solid solution of the composition, their solubility decreases with decrease in temperature. However, due to the fast solidification rate casting, so to room temperature, the solubility of the solid solution is substantially saturated.
