Met Infiltration Products

Well-Suited to Turbine Engine Hot Sections

Our melt infiltration (MI) ceramic matrix composites offer significant advantages over metallic hot gas path components in turbine engine applications. CMC components have a higher temperature capability, allowing them to operate with significantly reduced cooling flow. In aircraft engines, the lighter weight of CMC components compared to metallic components reduces fuel consumption, allowing longer range or more payload in aircraft.
