Metals used for die casting mainly include zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys. Although pressure cast iron is rare, it is also feasible. More specific die-cast metals include ZAMAK, Al-Zn alloys, and Alcoa standards: AA380, AA384, AA386, AA390, and AZ91D magnesium. The characteristics of die casting of various metals are as follows:

Zinc: The most easily die-cast metal, it is economical to manufacture small parts, it is easy to be coated, compressive strength, high plasticity, and long casting life.

Aluminum: Light weight, complex manufacturing and thin-walled castings, high dimensional stability, strong corrosion resistance, good mechanical properties, high thermal conductivity and electrical conductivity, and high strength at high temperatures.

Magnesium: easy to machine, high strength-to-weight ratio, and lightest among commonly used die-cast metals.

Copper: high hardness, strong corrosion resistance, commonly used die-cast metal in the best mechanical properties, wear resistance, strength close to steel.

Lead and tin: high density, high dimensional accuracy, can be used as a special anti-corrosion component. For public health reasons, this alloy cannot be used for food processing and storage equipment. Lead-tin alloys (sometimes also containing a little copper) can be used to make hand-printed letters and hot stamps in letterpress printing.
