Our SupremEX family of metal matrix composites (MMCs) offers a balanced combination of properties that is unmatched by conventional metals and alloys. SupremEX MMCs are stronger, stiffer and lighter, making them ideal for use in a wider range of demanding applications that include aerospace components, commercial and performance automotive pistons, satellite structures and optical systems. SupremEX MMCs offer a range of CTE's and good thermal conductivity applicable in many thermal management and electronics packaging applications.

SupremEX MMCs combine an ultrafine silicon carbide reinforcement with aerospace aluminum alloys. The resulting composites are superior to conventional alloys because they combine the lightweight properties of aluminum with outstanding strength and stiffness. SupremEX products can be used to replace aluminum, titanium, steel, other structural alloys and composites.

All SupremEX MMCs are beryllium free so they can be used in applications where non-beryllium materials are desired. We offer several grades with different metal to reinforcement ratios and different physical and mechanical properties to meet specific application requirements.
