Torque nut zinc die cast Metal Stamping part

Pressure casting zinc alloy: After the application of this alloy in the automobile industry in 1940, the production of this alloy increased dramatically, accounting for about 25% of the total zinc consumption. Advanced and applicable technologies are being adopted and developed rapidly. The most commonly used alloy system is Zn-Al-Cu-Mg system. Some impurities obviously affect the properties of die-cast zinc alloys. Therefore, the content of impurities such as iron, lead, cadmium and tin is strictly limited, with the upper limit of 0.005%, 0.004%, 0.003% and 0.02% respectively. Therefore, high purity zinc with purity greater than 99.99% should be selected as raw material for die-casting zinc alloy.
