Ferro Aluminium
SPECIFICATION
- Al: 30% / 35% min
Properties and Application
- Ferro alloy comprises iron and aluminium is Ferro Aluminium (FeAl)
- Aluminium content in ferro alloy is about 40 to 60 percent.
- Iron content in this ferro alloy is used for maintaining strength at high temperatures, reducing casting defects and improving hardness, tensile and yield.
- It is used in low melting point alloys and welding electrode manufacturing.
- It is also used in AlNiCo magnets and Ferro Aluminium Thermite.
- It can be added to steel to densify the resultant metal.
- Ferro Aluminium is used in the steel manufacturing as a deoxidizing agent
Description
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. The first recorded usage of the word “ferroaluminum” was in 1887. Ferroaluminum is also used in the process of nitriding, which is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. The aluminum provided in the alloy helps with this process. 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 aluminium obtaining process.
