Ferroaluminum information

Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium. The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel,^[1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.^[2] 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.^[3]

The first recorded usage of the word "ferroaluminum" was in 1887.^[4]^[5] Ferroaluminum can also be nitrided, as the aluminium bonds well with the nitrogen forming a hard case. The aluminum provided in the alloy helps with this process.^[6]^[7]^[8] The majority of the world's ferroaluminum is produced by Australia, China, Russia, the US and Canada, with the cost of electricity being the main factor in the aluminum smelting process.^[9]^[10]
