Die cast alloy stick refers to adhere to the walls of the mold cavity. This phenomenon is a great influence on the die casting process.
The solubility of die material in the molten alloy. Magnesium alloys have an advantage in this regard. The main alloy elements of die steel are insoluble or slightly soluble in magnesium alloys, such as iron, cobalt, manganese, aluminum, calcium, in addition to the nickel. So magnesium die casting material don't sticks mold.
The strength of castings in the ejection temperature. About 300 °C, The strength of the magnesium alloy is about half of the aluminum alloy, As long as the cavity surface is no problem, the launch is balanced, no shear stress, sufficient to ensure the castings mould relese in this hot strength.
Adhesion coefficient between the casting and the cavity surface. When the roughness between rubbing surface is 30/um and the rubbing speed is 0.1m/s, the adhesion coefficient between aluminum and steel is 0.1, while the adhesion coefficient between the magnesium and steel is 0.05. So magnesium die casting can use minimum demoulding inclination, and can obtain higher accuracy.
