Product Description

Product Description

 

What is Brown Fused Alumina?

Brown fused alumina (BFA) is a high-performance material primarily composed of aluminum oxide (Al2O3). It is produced by fusing bauxite, a natural ore containing aluminum oxide, in an electric arc furnace at high temperatures of around 2,000°C (3,632°F). The result is a hard, tough, and durable material that is ideal for use in abrasive products such as grinding wheels, sandpaper, and blasting media.

Brown fused alumina is typically brown in color due to the presence of iron oxide impurities, though it can also have other hues depending on the impurities present in the raw materials. Its hardness (9 on the Mohs scale) and high melting point make it suitable for demanding applications in industries where precision, strength, and reliability are essential.
 

 

Product Application

 

1. Grinding Wheels

Grinding wheels are one of the most common applications of brown fused alumina. Due to its hardness, BFA is ideal for precision grinding of metals, including steel, cast iron, and non-ferrous materials. It is commonly used in the manufacturing of bonded abrasive products such as grinding discs and wheels.
 

2. Polishing and Surface Finishing

In addition to grinding, brown fused alumina is often used for polishing and surface finishing. It can be used to smooth rough surfaces and create a polished, reflective finish on metals, plastics, and other materials.
 

3. Sandblasting

Brown fused alumina is frequently used as an abrasive blasting media for cleaning, etching, and surface preparation. Its high hardness and durability make it effective at removing rust, corrosion, old paint, and other contaminants from metal surfaces. 
 

4. Refractories

it is often used as a raw material in the production of bricks, castables, and other refractory products used in high-temperature environments such as furnaces and kilns. 
 

5. Bonded Abrasives

Brown fused alumina is a key ingredient in the production of bonded abrasives, which include grinding wheels, cut-off wheels, and other abrasive tools. These tools are used across a variety of industries for shaping, cutting, and finishing metals, ceramics, and composite materials.
