Customized for Use
Tailoring our production for specific applications like ceramic grinding wheels, we process our BFA with a 10,000 Gauss magnetic separator and validate it through firing trials, ensuring optimal performance.High Hardness:
BFA has a Mohs hardness of about 9, making it one of the hardest materials available, second only to diamonds. This high hardness makes it excellent for cutting, grinding, and abrasive blasting.
High Toughness:
Despite its hardness, Brown Fused Alumina exhibits good toughness, allowing it to withstand high-stress applications without fracturing easily.
Thermal Stability:
It can withstand high temperatures without losing its structural integrity, making it ideal for refractory applications.
Low Porosity:
Its low porosity means it has fewer spaces or voids in its structure, enhancing its strength and durability.
Corrosion Resistance:
BFA resists corrosion from gases and slag, which is beneficial in refractory linings and other applications exposed to corrosive environments.
Abrasion Resistance:
Its superior hardness and toughness make it highly resistant to wear and tear, ensuring longevity in abrasive applications.
What is Brown Fused Alumina Used For ?
Brown Fused Alumina (BFA) is a versatile abrasive material and refractory that finds applications in a variety of industrial processes due to its hardness, toughness, and thermal properties. Here are some of the primary uses of Brown Fused Alumina:
Bonded Abrasives
BFA is used in the manufacture of grinding wheels, cutting discs, and other bonded abrasive products where its hardness and durability contribute to efficient material removal.
Coated Abrasives
It is also used in making sandpaper, abrasive belts, and discs, providing a tough and durable cutting medium for surface preparation and finishing.
Refractory Materials
BFA's thermal stability and resistance to thermal shock make it an ideal material for refractory bricks, castables, and lining materials in furnaces, kilns, and incinerators.
Sandblasting
In abrasive blasting operations, BFA is used for surface cleaning, descaling, and preparation, removing rust, paint, and other coatings from metal and other surfaces.
Anti-Skid Surfacing
Its rough texture makes BFA an excellent choice for anti-skid flooring applications, such as on highways, bridges, and airport runways, ensuring safety and durability.
Polishing
BFA is used in the polishing of metals, glass, and stone to achieve a smooth finish. Its abrasive qualities allow for effective material removal and surface smoothing.Brown Fused Alumina's versatility across these applications is due to its combination of physical and chemical properties, making it a valuable material in industrial and manufacturing processes.

Tilt Furnace BFA Vs. Fixed Furnace BFA
Brown Fused Alumina (BFA) can be produced in different types of furnaces, with the two main types being the tilt furnace and the fixed furnace.
Each furnace type produces BFA with distinct characteristics due to differences in the manufacturing process. Here's a brief comparison of the two:
| Item | Tilt Furnace BFA | Fixed Furnace BFA |
| Process | Melting in a tiltable furnace allows controlled pouring and cooling. | Melting in a stationary furnace with material tapped out for cooling. |
| Properties | Higher toughness and more uniform crystal structure due to controlled cooling. | Higher hardness with aggressive cutting ability but slightly less uniformity in toughness and crystal structure. |
| Applications | Preferred for applications requiring high toughness and durability, such as heavy-duty grinding and abrasives. | Suitable for a wide range of abrasive applications where high cutting efficiency is desired, including coated and bonded abrasives, as well as refractory materials. |
The choice between tilt furnace and fixed furnace BFA depends on the specific application requirements. For applications that demand high toughness and durability, tilt furnace BFA might be the preferred option. In contrast, fixed furnace BFA is often chosen for its cutting efficiency and is used in a broader range of abrasive and refractory applications.
