    Introduction of 5 major benefits of aluminum alloy die casting


    Zinc and aluminum alloy die-casting are the first metals to be die-cast. Zinc and aluminum alloys have high ductility and excellent impact stress. In addition, they have a stronger anti-corrosion ability. Therefore, these characteristics make zinc and aluminum alloys more suitable for producing a variety of castings with complicated structures and thin walls. Therefore, the products are widely used in aviation, aerospace, shipbuilding, building materials, home appliances, various vehicles and instrumentation industries.
    So what are the advantages and benefits of aluminum die casting we know?
    Its advantages are mainly divided into five aspects:
    1. The thermal conductivity, electrical conductivity and cutting performance of aluminum alloy are good.
    2. The aluminum alloy wire shrinks less, so it has good filling performance, but the body shrinkage is large, and it is easy to generate large shrinkage holes in the final solidification.
    3. The aluminum alloy has small density and high strength, and its ratio of tensile strength to density is 9-15. When working at high temperature or low temperature, it also maintains good mechanical properties.
    4. The aluminum alloy die-casting is easy to stick mold. 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, hydrochloric acid, gasoline and various organic substances.
