Materion SupremEX® 640XA Aluminum - Silicon Carbide Metal Matrix Composite, T6 PGQ Forged Plate
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Aluminum Alloy; 6000 Series Aluminum Alloy
Material Notes:	SupremEX® 640XA is an aluminum metal matrix composite (AA6061) that offers an extremely high tensile modulus (nearly double that of the parent alloy), good static and fatigue strengths well in excess of high performance aluminum alloys, while retaining reasonable ductility. This composite also demonstrates superior elevated temperature strength and thermal stability when compared with conventional aluminum alloys. PGQ = Poly-Glycol Quench Information supplied by Materion.
Key Words:	AlSiC. Designation: – 6061/SiC/40p
