A20 Golden Color CBN Abrasive Powder For Metal Bond Vitrified Bond Application

A20 Golden Color Cubic Boron Nitride Abrasive Powder For Resin Bond Application

 

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 widely 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-A20, golden color, transparent monocrystal with regular shape and high toughness. Excellent truncated tetrahedron shape and self angular sharp. Great for highly demanded vitrified bond and metal bond tools, grinding wheels, also can be used for electroplated tools for processing ferrous metal and alloys.
