Borazon CBN is recognized as one of the greatest technological advancements for grinding hardened ferrous and superalloy materials. It is second in hardness only to diamond with twice the hardness and four times the abrasion resistance of typical conventional abrasives. Borazon CBN, with exceptional thermal conductivity, provides improved surface integrity in the grinding of hardened tool, die and alloy steels, as well as nickel and cobalt-based superalloys.
