Following World War II, returning servicemen complained that their Elgin watches couldn't take the punishment of corrosive environmental situations in various theaters of war. The Elgin National Watch Company, predecessor to today’s Elgiloy Specialty Metals, took those complaints to heart. After four years of research, "Elgiloy Alloy", a non-corroding watch spring material with an infinite life span was born.
This cobalt alloy with excellent corrosion, high strength and temperature properties was soon recognized for applications in aerospace, petrochemical applications and medical devices. As markets expanded, facilities were added to keep up with the demand for more wire and strip. Additionally, other cobalt and nickel alloys were added to the Elgiloy products. Today, Elgiloy produces more than 40 high-performance alloys.
