Black Cubic Boron Nitride Superabrasives CBN Powder B10

1. Cubic Boron Nitride Introduction

CBN (cubic boron nitride) superabrasive is with high hardness and high temperature resistance, four times that of traditional abrasive in wear resistance, and have extraordinary thermal conductivity.

CBN is widly used in grinding manufacturing market, from aerospace superalloys and thermal spraying to the hardened steel in automotive bearing and gear industry to improve efficiency and get the shortest processing time.

CBN-B10, with black color, irregular shape, medium toughness, high thermal stability, protruding acute angle, used in resin and vitrified bond system, providing high performance and efficiency.
