IMC Component

IMC – Advanced Materials for Superheated, Corrosion-Resistant Components

Intermetallic Composites (IMC) are advanced materials engineered to combine the unique properties of both electrically insulating and electrically conductive ceramics. This enables IMCs to be superheated through electrical resistance, making them ideal for extreme-temperature applications that also demand exceptional resistance to molten metals and corrosive environments. Kennametal leads in IMC technology, offering eight resistivity levels to meet various electrical resistance requirements and provide tailored solutions for high-performance industrial applications.
