Brown Fused Alumina (BFA), also known as Corundum or Artificial Fused Alumina, is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature (approximately 2000 degrees Celsius). It's characterized by its high hardness (9 on the Mohs scale), toughness, and sharp edges.
BFA primarily consists of Aluminum Oxide (Al2O3), with minor amounts of iron oxide (Fe2O3), silicon dioxide (SiO2), and titanium dioxide (TiO2). The structure of BFA is crystalline, which contributes to its hardness and toughness.
BFA ranks second only to diamond in terms of hardness. This hardness, along with its toughness, makes it a highly durable material, resistant to wear and tear. It's ideal for applications involving high stress and impact.
The particle size and grit of BFA can be customized according to specific requirements. It's available in a wide range of grit sizes, from coarse grits to micro grits, allowing for a variety of surface finishing and blasting applications.
Brown fused alumina exhibits low electrical and thermal conductivity. Its low thermal conductivity makes it a good choice for refractory applications, as it can withstand high temperatures without transferring heat.
BFA is widely used in blast cleaning and surface preparation due to its high hardness and toughness. Some of its applications include:
These properties make BFA a versatile abrasive material suitable for a variety of industrial applications.

Finding quality Brown Fused Alumina (BFA) from reliable suppliers is crucial to ensure the best performance in various industrial applications. Here are some factors to consider and the benefits of BFA.
The quality of BFA largely depends on the production process and the raw materials used. It's typically produced by the gradual melting reduction of calcined bauxite in an electric arc furnace. Understanding this process can help you evaluate the quality of BFA offered by different suppliers.
BFA comes in a variety of particle sizes and specs, depending on its intended use. For instance, coarse grits are ideal for heavy-duty applications such as blast cleaning, while finer grits are used for precision grinding and polishing. It's essential to choose a supplier that can provide the right specs based on your industry needs.
When choosing a BFA supplier, consider the following:
BFA should have excellent chemical stability to resist reactions that could affect its performance. Additionally, the quality should be consistent across batches to ensure predictable performance. Reliable suppliers will have stringent quality control measures to ensure these properties.
BFA's angular and sharp edges make it an excellent material for grinding and cutting applications. These properties allow it to cut through materials efficiently, leaving a smooth finish. This makes it ideal for use in industries such as metalworking, woodworking, and electronics.
