Materion SupremEX® 225XE Aluminum - Silicon Carbide Metal Matrix Composite, T4 CWQ, HIPed Billet
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy
Material Notes:	A high-quality aerospace grade aluminum alloy (2124A) reinforced with 25 vol.% silicon carbide particles which produces a metal matrix composite (MMC). 225XE is manufactured via a powder metallurgy route using a mechanical alloying process to ensure a homogeneous reinforcement distribution. This provides a refined grain structure enhances mechanical properties. The MMC is heat treatable, offering high strength and modulus for structural applications, and is available in billet, forged and extruded forms. Billet material is available supplied to AMS4355, designation: – 2124A/SiC/25p (3µm). Information provided by Materion.
