Iron and boron are combined to form Ferro Boron (Fe-B). Many applications demand durable, strong and specialist steel; it is where ferro boron plays a key role. It is added to the steel to improve its properties. This ferro alloy is most useful when it comes to the production of specialist steel, even though this production process is expensive. It can be used as the most economical boron additive for steel and several other ferrous metals. It is available in different forms, like ferro boron powder, ferro boron granules and ferro boron lump.

In the production of amorphous metals, Ferro Boron is used as an additive to impart desirable properties to the resultant alloy. Using Ferro Boron as an additive to an alloy is beneficial as it can increase resultant alloy's magnetic susceptibility and make it suitable for Nd-Fe-B magnets production. Deep quench ability of the resultant alloy is also increased with the addition of Ferro Boron. Ferro Boron also improves wash resistance property of an alloy.
