Ferroboron (FeB) is a ferroalloy consisting of iron and boron. The metal usually contains 17.5% to 20% boron and is used to produce specialist steels. The CAS Registry Number of ferroboron is 11108–67-1. Ferroboron 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. Another benefit of adding ferroboron to an alloy is that it increases the magnetic susceptibility of the end alloy, which makes it useful for producing neodymium magnets.^[1]^[2]^[3]^[4]
