Cubic Boron Nitride, commonly known as CBN, is a synthetic super abrasive material
second only to diamond in hardness. Because of its excellent thermal stability, wear
resistance, and chemical inertness, CBN powder is widely used in grinding, lapping,
polishing, and super abrasive tooling applications – especially for ferrous materials
where diamond abrasives may not be the best choice.
At AdValue Technology, we supply CBN powders for abrasive applications including
resin bond, vitrified bond, metal bond, and electroplated grinding tools. Our CBN
powders are available in different particle size ranges and grades to support
applications such as bonded abrasive tools, grinding wheels, lapping compounds,
polishing systems, and specialty abrasive formulations.
These cubic boron nitride powders are commonly used for grinding, lapping, and
finishing ferrous metals, hardened steels, cast iron, nickel alloys, and superalloys.
CBN powder is used in a wide range of precision abrasive and tooling applications,
including:
AdValue Technology can supply CBN powders in different size ranges and grades for
various abrasive applications.
