C355.0 is an aluminum-copper-magnesium casting alloy with silicon modification, used primarily in aerospace and high-performance applications requiring elevated temperature strength and dimensional stability. The T6 temper (solution heat-treated and artificially aged) provides tensile strengths of approximately 35–40 ksi with good bearing strength and moderate ductility, making it suitable for complex cast aerospace components operating at intermediate temperatures.
