Bodycote plc (LSE: BOY) is a leading supplier of heat treatments, metal joining, hot isostatic pressing and coatings services. Based in Macclesfield, United Kingdom, it is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The Company was founded by Arthur Bodycote in 1923 as a textile business under the name of G.R. Bodycote Ltd. It was acquired by Slater Walker in 1951 and demerged from them in 1973.

It refocused on its present activities in the 1970s: its expertise in bullet-proof and flame retardant clothing facilitated its transformation into the specialist materials sector. From 1979 onwards it made a series of acquisitions, the first of which was Blandburgh, a heat treatment business. In 1980 it went on to buy Zinc Alloy Rust Proofing Ltd, which was the beginning of its metallurgical coatings business.

In 1990 Bodycote acquired Metallurgical Testing Services Ltd (MTS) of Edinburgh from Murray International plc, laying the foundations for what would become Bodycote's materials testing business. In 2008 the materials testing division was sold to private ownership leading to the founding of the testing company Exova. In 1991 it bought HIP Ltd, a leading Hot Isostatic Processing business.
