Composition Element Effects (Alloying Elements in Aluminum)

Note: Cadmium (Cd) is listed in the chemical composition columns for reference with the source document, but is generally absent or kept at trace levels in these aluminum die casting alloys.

  • Silicon (Si): Improves aluminum fluidity, reduces shrinkage and hot cracking tendencies, and increases alloy strength, but reduces elongation. High silicon alloys (Si > 10%) are generally brittle.
  • Magnesium (Mg): Even small amounts significantly increase strength but reduce elongation.
  • Iron (Fe): The main impurity. It generally worsens mechanical properties but helps prevent die soldering/sticking to the mold.
  • Manganese (Mn): Neutralizes the harmful effects of Iron and improves high-temperature strength.
  • Copper (Cu): Significantly increases strength (especially at high temperatures) but reduces corrosion resistance.
  • Zinc (Zn): Increases strength but reduces high-temperature resistance and corrosion resistance.
