Dongguan Da Ling Shan Chang Sheng processing hardware store control of alloy composition alloy ingots from procurement beginning alloy ingots must be based on ultra-high-purity zinc-based, with ultra-high-purity aluminum, magnesium, copper alloy ingots formulated into a zinc alloy plate, supplier strict ingredient standards. Quality zinc alloy material is the production of superior quality cast zinc alloy bearings guarantee. And other new materials and nozzle back charge ratio, the charge should not exceed 50 percent return, most of the new material: old material = 70:30. Continuous melting alloy of aluminum and magnesium decreased. Dongguan Da Ling Shan Chang Sheng processing hardware store conditional casting plant is best centralized melting furnace zinc alloy, the alloy ingot and back charge ratio HDMI uniform metal shell, flux can be more effective use of zinc alloy, 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. Zinc Alloy European regulatory pins _ 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.
