Select the choice of which zinc alloy HDMI, three main aspects to consider the use of casting itself, need to meet performance requirements. Comprising: (1) the mechanical properties of zinc alloy electronic parts, the tensile strength of the zinc alloy products, is the maximum resistance of the material at break; elongation zinc alloy, is a measure of brittleness and ductility; hardness, the surface of a hard object pressed into the plastic deformation resistance or friction caused. (2) the state of the working environment: temperature, humidity, the workpiece contact media and air tightness requirements. (3) accuracy: accuracy and dimensional stability can be achieved. 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> 0.08% produces heat brittle , toughness decreases, decreased mobility. ② easily oxidized alloy loss at a molten state.
