Zinc and aluminum alloy die-casting are the first metals to be die-casted. Zinc and aluminum alloys have high ductility and excellent impact stress. In addition, they have stronger anti-corrosion ability. Therefore, these characteristics make zinc and aluminum alloys more suitable for producing various castings with complex structures and thin walls. Therefore, the products are widely used in aviation, aerospace, ships, building materials, home appliances, various vehicles and instrument industries.

    What are the advantages and benefits of aluminum alloy die castings that we know about?

    Its advantages are mainly divided into 5 aspects:

    1. Aluminum alloy has good thermal conductivity, electrical conductivity and cutting performance.

    2. Aluminum alloy has small shrinkage, so it has good filling performance, but the body shrinks large, 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, nitric acid, gasoline and various organic substances.
