QE22A is a magnesium alloy containing rare earth elements (primarily cerium and lanthanum) designed for elevated-temperature aerospace applications, offering superior creep resistance and strength retention up to approximately 300°C. The T6 temper (solution heat-treated and artificially aged) provides optimal mechanical properties and dimensional stability for sand-cast components in engines and structural applications operating under thermal stress.
