Dongguan Da Ling Shan Chang Sheng processing hardware store zinc alloy is zinc-based alloy by adding other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, zinc and titanium alloy low. Zinc alloy with low melting point, good fluidity British regulations zinc alloy pins, eutectic alloy of zinc, brazing and plastic processing zinc alloy die Which is strong, corrosion in the atmosphere, disability material to facilitate recycling and remelting; but the creep strength low, prone to dimensional changes caused by natural aging. Preparation of melting, casting, or pressure processing to become useful. According to the manufacturing process can be divided into cast zinc alloy and zinc alloy deformation. The main element zinc alloy aluminum supply zinc alloy jewelry, copper and magnesium. Zinc Alloy process can be divided into two types of deformation and cast zinc alloy. Cast zinc alloy fluidity and good corrosion resistance, suitable for die-meter automobile parts such as Shell. Dongguan Da Ling Shan Chang Sheng processing hardware store causes: the holes caused by: mainly porosity and contraction mechanisms are often circular pores, while the majority of irregular contractions. (1) pores causes: a liquid metal in the filling and solidification process, due to gas invasion, leading to the casting surface or internally generated holes. b paint out of the volatile gas intrusion. c alloy liquid gas content is too high, the precipitation during solidification. When the cavity in the gas, the coating volatile gases, gases evolved solidification, when the mold exhaust bad, eventually left in the pores formed in the casting. (2) shrinkage causes: a metal solidification process, because the volume is reduced or the final solidification of liquid metal parts are not feeding, and produce shrinkage.
