What are the properties of brown fused alumina?

Brown Fused Alumina is also known as emery. Its main chemical component is AL2O3, with a content of 95.00%-97.00%. It also contains a small amount of Fe, Si, Ti, etc. So what are the properties of Brown Fused Alumina? Today, the editor of Haixu Abrasives will introduce to you the properties of Brown Fused Alumina.

Brown Fused Alumina is made by smelting high-quality bauxite, iron filings and anthracite at high temperature in an electric arc. It is crushed and shaped by an autogenous grinder, magnetically separated to remove iron, and screened into various particle sizes. Brown Fused Alumina is the most basic abrasive because of its grinding properties. It has good performance, wide application range, low price and is widely used.

Properties of Brown Fused Alumina:

1. Brown Fused Alumina has the performance characteristics of high purity, good crystallization, good self-sharpening, strong fluidity, low expansion coefficient, corrosion resistance, high temperature resistance, and stable thermal performance.
2. Brown Fused Alumina products have the characteristics of no explosion, no cracking, and no easy powdering during application. They have strong grinding ability, good wear resistance, high use efficiency, and good production efficiency.
3. Less dust: The specific gravity of Brown Fused Alumina is relatively high compared to other abrasives, so it generates less dust during use, which not only improves the operator’s operating efficiency
4. High efficiency: When the particles are small, the speed of particles in the airflow becomes faster. Moreover, the shape has sharp edges and corners, which hit the surface of the object to be operated during rapid operation, thereby achieving the purpose of sandblasting or grinding.
