About Us

Special Metals Wiggin Limited (SMWL) operations in Hereford, England, traces its roots back to Henry Wiggin & Company, which began making speciality alloy products in 1835. In 1929 the Wiggin operations became part of the International Nickel Company (INCO Alloys) and shortly after, during World War II, the NIMONICĀ® family of alloys for gas turbine engines were created by the Wiggin research team - an essential wartime development. The present site in Hereford was established in 1954 and it became the main UK production site in 1961.
