Description of Brown Fused Alumina

Brown Fused Alumina Product Size:

Brown Fused Alumina, also known as corundum, is a tan artificial corundum obtained by melting and reducing three raw materials of bauxite, carbon material and iron filings in an electric arc furnace, hence the name. The main chemical composition of brown corundum is AL2O3, its content is 95.00%-97.00%, and it also contains a small amount of Fe, Si, Ti and so on. Brown Fused Alumina is the most basic abrasive and is widely used because of its good grinding performance, wide application range and low price.

The main component of Brown Fused Alumina is alumina, and the grade is also distinguished by the aluminum content. The lower the aluminum content, the lower the hardness. Product granularity is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size number is F4~F320, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact-resistant. Because it is processed and broken by a self-grinding machine, the particles are mostly spherical particles, the surface is dry and clean, and it is easy to bond with a binder.

Application of Brown Fused Alumina

1, Grinding and Polishing Materials

The surface polishing process with Brown Fused Alumina abrasives has low pressure, which avoids leaving very fine lines on the surface of the steel plate. The polishing workpiece has good consistency, the workpiece will not burn, and the processing efficiency is high.

2, Making Resin Abrasives

Use 30%-50% of Brown Fused Alumina and black corundum to compound to make resin abrasives. Compared with traditional resin abrasives, the resin abrasives made of this composite abrasive have significantly improved sharpness and higher cut or grinded finish. , the color becomes smaller. Due to the low cost, resin abrasive tools made of composite abrasives have high cost performance.

3, Making Coated Abrasives

The application of Brown Fused Alumina series products in the field of resin abrasives and coated abrasives is to replace some other abrasives, and partially replace other abrasives to make abrasives. High-cost abrasives are equivalent, but they will reduce the production cost of abrasive tools and greatly improve the cost performance.
