Iron aluminide (AlFe3)-Powder

Iron aluminide (AlFe3)-Powder introduce:

Characteristic




Iron aluminides are intermetallic compounds of iron and aluminium - they typically contain ~18% Al or more.




Good oxide and sulfur resistance, with strength comparable to steel alloys, and low cost of materials have made these compounds of metallurgical interest - however low ductility and issues with hydrogen embrittlement are barriers to their processing and use in structural applications.




Chemical formula：Fe3Al

Molar mass:194.52 g/mol

Appearance：Gray Powder, Intermetallic

Density：6.72 g/cm3

Melting point:1540 °C

Application




Substitute for stainless steel with better high temperature strength. Good corrosion resistance in sulfidizing environments.

Potential uses for iron alumides include : electrical heating elements, piping and other work for high temperature process including piping for coal gasification and for superheater and re-heater tubes. It has also been suggested as a structural material for lunar use.
