Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium. The metal usually consists of 40% to 60% aluminium and applications of ferroaluminum include the deoxidation of steel, hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes. The alloy is also known for the ability to manufacture low melting point alloys and its ability to carry out aluminothermic welding. Ferroaluminum does not currently have a CAS Registry Number. The presence of iron in aluminum helps in the decrease of casting defects, improves tensile, yield, hardness, and maintains strength at high temperatures.
