Types and characteristics of metals commonly used in die casting

The main metals used in die casting include zinc, copper, aluminum, magnesium, lead, tin and lead tin alloys. Although die-cast iron is rare, it is possible. Some of the more unusual die-cast metals include ZAMAK, aluminum and zinc alloys, and Alcoa standards: AA380, AA384, AA386, AA390, and AZ91D magnesium. Several main metals that Sieg-Huao uses are aluminum alloy, zinc alloy and magnesium ally. Die-casting characters of various metals are as follows.

Zinc: the easiest metal to be die-casted, very economical when making small parts, easy to be coated, with high compressive strength, high plasticity, and long casting life.

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

Magnesium: easy to machine, with high strength and weight ratio; It is usually the lightest die - casting metal.

Copper: high hardness, strong corrosion resistance, mechanical properties of commonly used die - casting metals, wear resistance, strength close to steel

Lead and tin: high density, high dimensional accuracy, can be used as special anti-corrosion parts. For public health reasons, this alloy cannot be used as food processing and storage equipment. An alloy (and sometimes a bit of copper) of lead, tin, and antimony can be used to make hand-printed type and gilding in letterpress printing.

The maximum mass limit for die casting using aluminum, copper, magnesium and zinc is 70 pounds (32 kilograms), 10 pounds (4.5 kilograms), 44 pounds (20 kilograms) and 75 pounds (34 kilograms), respectively.
