Ferro boron can improve the quenching degree and mechanical behavior of steel and in high-quality alloy steel, boron takes the place of chromium, molybdenum and nickel, and do es not affect their mechanical behavior.


Ferroboron is stable under normal storage and handling conditions.

A key benefit of adding ferroboron to an alloy is that it can drastically increase the magnetic susceptibility of the end alloy, thereby making it suitable for the production of Nd-Fe-B magnets.

Another benefit is it can drastically increase the deep quench ability of the end alloy.

Ferro Boron Applications

  • To improve the hardenability of C-Mn and low alloy steels
  • Improvement of steel and nitrogen scavenging
  • As low loss materials for NdFeB magnets
  • In the production of low carbon cold working wire rod
  • In the production of automotive sheet steels
  • Incorporation into amorphous metal materials for transformer cores
  • In hot spray painting
  • Improvement of hardenability of low alloyed steels
  • In the boration surface treatment of steels
  • In the reduction of nitrogen
  • Manufacturing of metallic glass.
