  • Patent number: 11807918
    Abstract: Disclosed are an aluminum alloy for a die casting and a method of producing an aluminum alloy casting product. The aluminum alloy may include silicon (Si) in an amount of about 7.5 to 9.5 wt %; magnesium (Mg) in an amount of about 2.5 to 3.5 wt %; iron (Fe) in an amount of about 0.5 to 1.0 wt %; manganese (Mn) in an amount of about 0.1 to 0.6 wt %; and aluminum (Al) constituting the remaining balance of the aluminum alloy, all the wt % are based on the total weight of the aluminum alloy.

  • Patent number: 11293080
    Abstract: Disclosed are a magnesium die casting alloy, and an alloy composition for improving thermal conductivity and electrical conductivity. A magnesium die casting alloy includes an amount of about 0.5 to 2.0 wt % of aluminum (Al) and the balance magnesium (Mg), based on the total weight of the magnesium die casting alloy. Accordingly, an alloy, which has high thermal conductivity and electrical conductivity as compared to a conventional AZ91D magnesium alloy, is obtained.
