Abstract:
1. An Al—Si—Mg alloy composition used to produce a cast product having a critical fracture strain of at least about 10%, the alloy comprising: about 6.0 wt % to about 7.8 wt % Si; about 0.10 wt % to about 0.18 wt % Mg; less than or equal to about 0.35 wt % Cu; less than or equal to about 0.6 wt % Mn; less than or equal to about 0.15 wt % Fe; and a balance of aluminum and impurities; wherein, the composition is capable of producing a cast product having a critical fracture strain of at least about 10% and a tensile yield strength of at least 100 MPa when
