  Zinc and aluminum alloys were the first metals to be die-casted. This type of alloy has high ductility, excellent impact stress and stronger corrosion resistance. It is suitable for producing all kinds of castings with complex structure and thin wall. It is widely used in aviation, aerospace, ships, building materials, home appliances, various vehicles and instrument industries.  The advantages of aluminum alloy die-casting mainly have 5 aspects: 1. Aluminum alloy has better thermal conductivity, electrical conductivity and cutting performance. 2. Aluminum alloy has a small shrinkage, so it has good filling performance, but the body shrinks a lot, and it is easy to generate large shrinkage holes at the final solidification. 3. Aluminum alloy has low density and high strength, and the ratio of tensile strength to density is 9-15. It also maintains good mechanical properties when working at high or low temperatures. 4. Aluminum alloy die-casting is easy to stick to the mold, and the mass fraction of die-cast aluminum alloy iron is generally controlled in the range of 0.8% to 0.9% to reduce the sticking phenomenon. 5. Aluminum alloy has good corrosion resistance and oxidation resistance. Most aluminum alloys have good corrosion resistance in fresh water, sea water, concentrated nitric acid, nitro-hydrochloric acid, gasoline and various organic substances.
