Kennametal Inc
A maker of tungsten carbide-based cutting tools, tooling, wear components, and metallurgical powders, sold under brands like Kennametal and WIDIA to metal-cutting, aerospace, energy, and earthworks customers worldwide. Metallurgist Philip M. McKenna founded it in 1938 in Latrobe, Pennsylvania, as the McKenna Metals Company to sell his breakthrough tungsten-titanium carbide alloy. The business later renamed itself after that flagship product, "Kennametal."
