SUPREMEX® METAL MATRIX COMPOSITES IMPROVE PERFORMANCE IN COMMERCIAL AND MILITARY AEROSPACE APPLICATIONS 

With increasing emphasis on reducing fuel costs and carbon emissions in commercial aerospace applications, companies must find ways to adapt to these industry needs. Using lighter component materials is one solution. Materion’s SupremEX aluminum silicon carbide metal matrix composites (MMCs) are ideal for use in aero-engine components such as bushings and bearings and aircraft structures because they offer high strength and wear resistance but with significant weight savings. Reducing component weight while meeting strength and wear requirements results in reduced fuel use and lower carbon emissions. 

The weight savings achieved using SupremEX MMCs rather than other materials is significant as these composites are nearly 70 percent lighter than bronze, 60 percent lighter than steel and 38 percent lighter than titanium. And SupremEX MMCs increase component capability due to their high strength and stiffness properties. While components made of SupremEX composites are as light as some carbon fiber parts, they offer increased ductility, which results in superior damage tolerance and improved resistance to wear. With a low coefficient of thermal expansion, components made of these MMCs will also maintain tighter dimensional control over the broad range of temperatures typically experienced during flight.

BALANCED PROPERTIES AND PERFORMANCE CHARACTERISTICS 

SupremEX composites offer a unique, balanced property combination that includes:

  • Exceptional stiffness
  • High strength
  • High fatigue strength (twice that of aluminum alloys)
  • High tensile strength at elevated temperatures
  • Wear resistance
