Boron Carbide Powder

Boron Carbide Powder is often used for lapping, polishing, grinding, sintering, hot pressing forms, as well as unique applications such as radiation shielding, bullet-proof vests, tank armor. Boron Carbide has a hardness (9.3 – 9.5 Mohs) and chemical resistant properties similar to Diamond – thus being nicknamed “Black Diamond”. Boron Carbide Abrasive Powders deliver high surface quality and allow high removal rates in lapping, wire sawing, and ultrasonic drilling operations. The advantage of using 3M boron carbide grits instead of silicon carbide, tungsten carbide, or titanium carbide is that, unlike these other lapping agents, boron carbide has a substantially higher hardness. It allows rapid machining, making it a timesaving option for machining wear-resistant materials such as tungsten carbide and technical ceramics, including alumina (Al2O3), zirconia (ZrO2), and silicon carbide (SiC). Boron carbide gives a matte appearance to the lapped surface. Our boron carbide powders are available in grit sizes according to FEPA standards.
