Materion SupremEX® 225CA Aluminum - Silicon Carbide Metal Matrix Composite, T4, HIPed Billet
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy
Material Notes:	A high-quality aluminum alloy (2124A) reinforced with 25 vol.% silicon carbide particles which produces a metal matrix composite (MMC). 225CA is manufactured via a powder metallurgy route using a mechanical alloying process to ensure a homogeneous distribution of reinforcement. This provides a refined grain structure and enhanced mechanical properties. The 225CA MMC is heat treatable, offering high strength and elastic modulus for structural applications. 225CA is available in a variety of shapes including billet and forgings.
