Home Products Metal Matrix Composites SupremEX Commercial and Performance Automotive BETTER PERFORMANCE IN AUTOMOTIVE APPLICATIONS SupremEX® aluminum silicon carbide metal matrix composites (MMCs) are ideal to meet demands to reduce overall vehicle weight and improve engine efficiency in both performance and commercial automotive markets. SupremEX MMCs can be used for multiple applications, including engine components, suspension systems and chassis. SUPREMEX® MMC IN COMMERCIAL AUTOMOBILES In the commercial automotive market where emphasis is on carbon dioxide reduction and better fuel efficiency, SupremEX 225XE offers higher material performance than industry standard aluminum alloys. SupremEX composites reduce connecting rod weight 65 percent and provide fatigue strength two times that of aluminum alloys. In addition, engine components made of SupremEX are wear resistant and have low friction characteristics that result in reduced wear when running against other materials. SUPREMEX® MMC FOR HIGH PERFORMANCE AUTOMOBILES In high performance and racing automotive applications, SupremEX MMCs offer multiple options for achieving improved results. Structural components and Body in White (BiW) frames made of SupremEX 620XF reduce body weight 25 percent over those constructed of conventional materials. Pistons made of SupremEX 225 are more efficient, providing improved power and enhanced combustion for reduced CO2 emissions. And, in suspension systems, SupremEX has a strong record for reliable, lightweight suspension upright and steering knuckle components that enhance vehicle dynamics. SUPREMEX® COMPOSITE ADVANTAGES SupremEX composites offer a unique, balanced property combination that includes: Exceptional stiffness High strength High fatigue strength (twice that of most aluminum alloys) High tensile strength at elevated temperatures Wear resistance SUPREMEX® PRODUCTS FOR PERFORMANCE & COMMERCIAL AUTOMOTIVE The SupremEX product family includes a range of high specific strength and specific stiffness to meet a variety of automotive requirements: SupremEX 225XE – 2124/SiC/25p SupremEX 620XF – 6061/SiC/20p SupremEX 640XA – 6061/SiC/40p FORMS AVAILABLE SupremEX composites are available in: HIP Billets (hot isostatic pressing) Forged Plates or Shapes Extruded Profiles Rolled Sheets OTHER MATERION MATERIALS FOR AUTOMOTIVE APPLICATIONS AMC4632 - an aluminum silicon alloy for weight reduction and stability at elevated temperatures ToughMet - a copper nickel tin alloy for friction and wear resistance along with dimensional stability Alloy 10X - a copper cobalt beryllium zirconium alloy for improved high temperature strength and ductility PerforMet™ - a copper nickel silicon chromium alloy for high hardness at high temperatures CONTACT MATERION AEROSPACE METAL COMPOSITES For more information about using SupremEX for your performance and commercial automotive applications or choosing the grade that best meets your requirements, contact us today.
