Dongguan Da Ling Shan Chang Sheng processing hardware store magnesium role: ① ② reduce intergranular corrosion refined alloy, thereby increasing the strength of the negative ③ alloy improved wear resistance of the alloy: ① magnesium content> is 0.08% HDMI, generate heat brittle, toughness decreases, decreased mobility. ② easily oxidized alloy loss at a molten state. Magnesium alloy liquidity Dongguan Da Ling Shan Chang Sheng processing hardware store impurity elements: iron ① iron and aluminum react to form inter-metallic compounds Al5Fe2, causing loss of aluminum elements and the formation of dross. ② the formation of hard particles of zinc alloy die castings in the EU regulation pins, after the impact of processing and polishing. ③ increase the brittleness of the alloy. The solubility of iron in molten zinc is increased with increasing temperature, the furnace temperature of molten zinc every change will lead to excessive iron saturation (when the temperature drops), or unsaturated (when temperature rises). When the iron saturation, in the over-saturation of the iron reaction will occur and aluminum alloys, the result is caused by increase in the amount of dross. When unsaturated iron-zinc alloy, zinc alloy pot and corrosion gooseneck material will be enhanced, in order to return to saturation. Two kinds of temperature change of a common result is the final result of the consumption of aluminum element, formation of additional dross. HDMI, zinc alloy, Chang Sheng Hardware provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
