Carpenter Technology Corporation
A maker of high-performance specialty alloys used in aerospace, defense, medical, and energy parts, running two divisions: its main alloy operations and a Performance Engineered Products unit behind brands like Dynamet titanium. Founded in 1889 in Reading, Pennsylvania, as the Carpenter Steel Company by Civil War veteran and engineer James Henry Carpenter, it once made armor-piercing shells for the U.S. Navy. In 1997 it bought Dynamet to expand into titanium, which now supplies metal for medical implants and surgical instruments.
