Abstract
An alloy composition is provided. The alloy composition includes silicon (Si) at a concentration of greater than or equal to about 0.55 wt. % to less than or equal to about 0.75 wt. %, magnesium (Mg) at a concentration of greater than or equal to about 0.55 wt. % to less than or equal to about 0.75 wt. %, chromium (Cr) at a concentration of greater than or equal to about 0.15 wt. % to less than or equal to about 0.3 wt. %, and a balance of the alloy composition being aluminum (Al). The alloy composition has an intermetallic phase content of less than or equal to about 3 wt. %. Methods of preparing the alloy composition and of processing the alloy composition are also provided.
