D357.0 T6 is a high-strength aluminum casting alloy (Al-Si-Cu-Mg) in solution heat-treated and artificially aged condition, used primarily in aerospace applications requiring excellent castability and elevated-temperature strength up to approximately 300°F. The T6 temper delivers high yield and tensile strength with good bearing strength characteristics, making it suitable for critical structural and load-bearing cast components where dimensional precision and strength consistency are required.
