Materion SupremEX® 215XK MMC Aluminum - Silicon Carbide Metal Matrix Composite, T6 CWQ, Forged Plate
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy
Material Notes:	SupremEX® 215XK MMC is a high quality, aerospace-grade aluminum alloy (2009) reinforced with 15 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 enhancing mechanical properties. SupremEX 215XK is heat treatable, offering high strength and modulus for structural applications. It is available in billet, forged and extruded forms. Designation: – 2009/SiC/15p (5 µm). Benefits Weight saving versus titanium alloys High fatigue and fretting fatigue resistance Increased modulus versus aluminum alloys Hardness, wear resistance and low friction characteristics Good machinability using conventional techniques Homogenous and stable microstructure Information provided by Materion.
