A ferro alloy comprises iron and aluminium is Ferro Aluminium (FeAl). The aluminium content in ferro alloy is about 40 to 60 percent. Low melting point alloys can be manufactured using this ferro alloy. It can also use be used in aluminothermic welding. The iron content in this ferro alloy is beneficial for maintaining strength at high temperatures, reducing casting defects and improving hardness, tensile and yield.
