355.0 aluminum alloy is a Si-Cu casting alloy used for aircraft engine components and structural castings requiring moderate strength and thermal fatigue resistance. T6 temper (solution heat-treated and artificially aged) provides tensile strength around 40-48 ksi with good bearing strength and moderate ductility, suitable for temperatures up to approximately 300°F.
