Product Description

Product Description:


White Aluminum Oxide is the product of a carefully regulated manufacturing process. Using the highest quality of Bayer process alumina as raw material, its furnacing practices are tailored to ensure the highest level of purity and the optimum crystal structure is achieved. Furthermore, it is crushed to create a distinctive blocky grain distribution with an increased bulk density.


Due to its friability and excellent cutting ability, White Fused Alumina for Abrasives is a popular choice for precision grinding on high speed steels, segments and internal grinding applications. Moreover, it is an ideal option for grinding heat sensitive alloys.





  • Control over the production process; manufacturers have complete control over the production process, allowing them to ensure the quality of their products and respond quickly to any issues or changes in demand.
  • Cost savings; by producing raw materials in-house, manufacturers can avoid the markup associated with purchasing from third-party suppliers, leading to significant cost savings in the long-term.
  • Customization; raw manufacturers can create custom formulations and adjust their processes to meet specific customer needs.
  • Inventory management; raw manufacturers can manage their inventory more effectively, reducing waste and eliminating stockouts.



  • High purity and stability; close texture.
  • High hardness, angular shape and good self-sharpening; strong grinding ability, small heat, high efficiency and acid and alkali corrosion resistance.
  • High processing speed and high quality without affecting the colour of the workpiece after processing.

White corundum abrasive is a versatile abrasive that can be used to give a wide array of products an attractive finsh. It is suitable for use on high-end products, process or hardware and can increase the adhesion of the coating.


It is effective for derusting and removing oxidation from iron workpieces as well as strengthening the aluminum surface and giving it a glossy finish. It is also useful for removing oxidation from copper workpieces to give a matte effect.


White corundum can be used as a solid coated abrasive for wetting and dry sand blasting. It can also be used as a super fine grinding or polishing tool particularly when used on high-grade refractory materials such as crystals or those found in the electronics industry.

Finally, it can be used to provide a frosted finish to glass products, a matte effect for engraved plastic, and a plush or pattern processing for special fabrics such as denim.



Fine-tech's White Aluminum Oxide is a high-grade abrasive material. It is made with aluminum oxide and is used to create wear-resistant floor coatings and for white fused alumina abrasive grits. With its hardness of 9.0 Mohs, it can be used in a variety of applications.
