300-250um White Aluminum Oxide Segmental Grits Polishing
1. Introduction
White aluminum oxide is made from high purity Bayer process alumina. Raw materials and furnacing practices are carefully controlled to ensure the highest purity and optimum crystal structure. It is crushed in such a manner to produce blocky grain distributions with a higher bulk density.
The hardness of white corundum is slightly higher than brown corundum, toughness is slightly lower, which has high purity, good self-sharpening, strong grinding ability, small heat, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability.

5. Flexural strength: 480 MPa
3. Advantages
1. Ability to source raw materials locally
2. Sustainability
3. High processing speed and high quality
4. Raw manufacturers can create custom formulations and adjust their processes to meet specific customer needs. This level of customization can be difficult to achieve when relying on third-party suppliers.
4. Applications
1. White Aluminum Oxide is an excellent senior ceramic material, which is widely used in industry because of its high hardness, good wear resistance and corrosion resistance, etc. The following are the white corundum applications.
2. White Aluminum Oxide abrasives are mainly used in the grinding and polishing of metal parts, as well as in the manufacture of processing tools such as knives.
