Alliant Castings provides a wide range of wear resistant alloys, including custom alloys to meet specific customer needs. Our alloys fall into three broad families:
NiHard Family, developed in the 1920’s to increase the market for nickel, Nihard uses nickel and chromium in cast iron to produce a wear resistant microstructure. Typically, Nihard is used in sliding abrasion application where there is limited impact.
High Chrome Family, developed around 1915 in anticipation of alloy shortages due to WW1. This family of alloys utilizes chromium levels ranging from 15-28%. The combination of carbon and chromium develop chromium carbides in the wear resistant mircrostructure. Chrome Iron provides better impact resistance and abrasion resistance, often at little extra cost. Within the high chrome family we are especially proud of AC800, a proprietary alloy that marries Hi Chrome chemistry with optimum heat treatment to provide an exceptional level of abrasion resistance.
Carbidic Austempered Ductile Iron (CADI) Family combines the toughness of ductile iron as well wear resistance found in abrasion resistant irons. CADI is a material that uses a matrix of ausferrite, carbides and nodular graphite to add strength and wear resistance. The result is an alternative to conventional steel and iron parts.
