everal advantages of aluminum alloy die castings

Aluminum alloy die castings are more suitable for the production of various castings with complex structures and thin wall thicknesses. Therefore, the products are widely used in aviation, aerospace, ships, building materials, household appliances, various vehicle instruments and other industries. We know what are the advantages and benefits of aluminum alloy die casting? Its advantages are mainly divided into five aspects:

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

2. The linear shrinkage of aluminum alloy is small and the filling performance is good, but the volume shrinkage is large, and it is easy to form large shrinkage holes at the final solidification point.

3. The ratio of tensile strength to density of aluminum alloy is 9 to 15. It also maintains good mechanical properties when working at high or low temperatures.

4. Aluminum alloy is easy to stick to the mold during the die casting process. The mass fraction of iron in the die-casting aluminum alloy is generally controlled between 0.8% and 0.9%, which can 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 and hydrochloric acid, gasoline and various organic compounds.
