[0002] Aluminum-magnesium alloy usually refers to aluminum alloy with magnesium as the main added element. It has the advantages of high strength, low density, and good heat dissipation. It is widely used in electronics, automobiles, aerospace and other fields. Die casting is a pressure-casting part. It uses a pressure-casting mechanical die-casting machine with a casting mold installed. The liquid copper, zinc, aluminum or aluminum alloy is poured into the inlet of the die-casting machine.
