Detailed Product Description: | 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 when zinc alloy handle, 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 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. Such as Dongguan Da Ling Shan Chang Sheng new materials and processing hardware store outlet 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. When the outlet material melting, we must strictly control the melting temperature should not exceed 420 ℃, in order to avoid the loss of aluminum and magnesium. Conditional best casting plant centralized melting furnace zinc alloy zinc alloy pins EU regulations, the alloy ingot and back charge uniform ratio, flux can be more effective use of the alloy composition and the temperature is kept uniform and stable. Electroplating waste, fines should be a separate furnace. Zinc Alloy European regulatory pins | Zinc | Chang Sheng Hardware provided by Dongguan Da Ling Shan Chang Sheng processing hardware store. Dongguan Da Ling Shan Chang Sheng processing hardware store (shop1379091614724.1688.com) strong, credible, in Dongguan, Guangdong and other hardware accessories industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Chang Sheng Hardware and you hand into the brilliant, for a better future! |
