Technology

FRA Composites® (FRA) is a high strength aluminum alloy randomly reinforced with chopped ceramic (alumina-silicate) fibers.  The ideal applications for FRA are those that capitalize on its excellent wear resistance, light weight and elevated temperature strength properties.  Tests have proven that compared to steel and cast iron, this material has equivalent or better resistance to various forms of wear (abrasive, fretting, metal-to-metal sliding).  FRA is also only 1/3 the density of ferrous alloys.  

Furthermore, compared to conventional high strength aluminum alloys, FRA has > 3X elevated temperature strength.
