Monocrystalline Fused Alumina

Introduction

Monocrystalline fused alumina, melting at high temperature by special process, is a high-end grinding material. The abrasive particles are off-white.

Features and Advantages:

1.Low sodium, below 0.2%

2.High hardness

3.High toughness

4.High bulk density and high wear resistance

5.High-end abrasive material

6.Small crystal, not easy to damage the workpiece

QC

To the monocrytalline fused alumina, the chemical composition of Al2O3, SiO2, Fe2O3,K2O,Na2O need to be tested, also very strick with the inspection of the bulk density.

Applications

1. It’s mainly used for making advanced cutting and grinding tools.

2. It’s suitable for grinding high-hardness, high-toughness materials such as high-vanadium high-speed steel, austenitic stainless steel, and titanium alloys.

3. It is used for dry grinding and grinding work which is easy to deform and burn.

4. It is suitable for various abrasive tools such as resin, ceramics, coating, etc.

5. It can be used for high temperature bonding agent molding, and won’t fade after high temperature sintering.
