RSP Technology RSA-431 T6 Aluminum Super Alloy
Categories:	Metal; Nonferrous Metal; Aluminum Alloy
Material Notes:	Pistons, precision equipment, high strength-high temperature; Specifically developed for racing pistons Features: High strength and fatigue at elevated temperatures (150 - 450C), low density, low CTE, high stiffness, Good wear resistance Applications: racing pistons for micro engines, 2-strokes, 4-strokes precision equipment combining high strength, high stiffness and low CTE Replacing: conventional AA4032, AA2618, M-142, titanium RSP Technology develops, produces and sells aluminium super alloys with high end properties. By using its own Meltspinning process, ultra fast cooling rates can be reached, converting more than 1 million degrees per second. As a result very fine nanostructured alloys with new functionalities are being developed and produced. Information provided by RSP Technology BV
