Materion SupremEX® 640XA MMC Aluminum - Silicon Carbide Metal Matrix Composite, T7, Billet
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy
Material Notes:	SupremEX® 640XA MMC is a high quality, aerospace-grade aluminum alloy (6061B) reinforced with 40 vol.% silicon carbide particles. This composite material is manufactured via powder metallurgy using a mechanical alloying process to ensure a homogeneous reinforcement distribution, providing a refined grain structure and enhanced mechanical properties. SupremEX 640XA MMC is heat treatable, offering high strength and modulus with a CTE match to nickel plating (13 ppm/°C). This material is excellent for lightweight, high-stability structural applications. Designation: 6061B/SiC/40p (3 µm). Benefits Weight saving Static strength comparable to high-strength Al alloys Exceptional specific stiffness for increased component stiffness High fatigue resistance Refined, homogeneous and stable microstructure Excellent hardness, wear resistance and low friction characteristics Good machinability using high-speed machining techniques Superior thermal stability, with CTE match to Ni plating Information provided by Materion.
