New high tension Silumins were investigated by properly adding several elements, such as Mg, Mn, Cu, Cd, Cr, Sn, Sb, Zn, and Fe in Al-Si alloys, and tested mechanical and anti-corrosion properties on 45 kinds of these alloys. As the base alloy, Al-Si-Mg alloy was taken because Mg is the indispensable element for precipitation hardening effect. Al-Si-Mg alloy containing Cu-Sn-Sb is found to be the best of all the Silumins and the base alloy with Mn-Cu-Cd-Sb, Mn-Cu-Sn-Sb, Mn-Cu-Cd, and Sn-Sb can also be called High Tension Silumins.
