Haxonite is an iron-nickel carbide mineral found in iron meteorites and carbonaceous chondrites. It has a chemical formula of (Fe, Ni)23C6, crystallizes in the cubic crystal system and has a Mohs hardness of 5.5 – 6. It is iron-nickel carbide mineral.
It was first described in 1971 and named after Howard J. Axon (1924–1992), a metallurgist at the University of Manchester, Manchester, England. Co-type localities are the Toluca meteorite, Xiquipilco, Mexico and the Canyon Diablo meteorite, Meteor Crater, Coconino County, Arizona, US.
