Our Heritage

Our history spans more than a century of products, processes, and most of all, people. Also captured is the introduction of many well-known nickel- and cobalt-base alloys that have been used worldwide in the most demanding environments and in critical applications for aerospace, power generation, chemical processing, pharmaceuticals, and other areas.

In 1894, when Elwood Haynes drove his “Pioneer” automobile down Pumpkinvine Pike here in Kokomo, Indiana, he set in motion an inventive spirit. He was a tireless inventor who developed the unique metal alloys that led to the foundation of Haynes International, instilled our commitment to alloy excellence, and inspired our Tradition of Innovation.
