Materion SupremEX® 620XF MMC Aluminum - Silicon Carbide Metal Matrix Composite, T5, Precision Extrusion
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy
Material Notes:	SupremEX® 620XF MMC is a high-quality aerospace grade aluminum alloy (6061B) reinforced with 20 vol.% silicon carbide particles. 620XF is manufactured via a powder metallurgy route using a mechanical alloying process to ensure a homogeneous reinforcement distribution. This provides a refined grain structure, enhancing mechanical properties. The MMC is heat treatable, offering high strength and modulus for structural applications, and is available in billet, forged and extruded forms. Designation: – 6061B/SiC/20p (0.7µm). Advantages Precision section extrusion using standard dies, enabling weight saving through reduced wall thickness High stiffness and strength Robust and ductile for damage resistance Good corrosion and fatigue performance Thermally stable Information provided by Materion.
