Brown fused alumina (BFA) is a synthetic abrasive material made from calcined bauxite, coke, and iron filings in an electric arc furnace. It is also known by the name of brown aluminum oxide. This material has a brown color and a high level of hardness, making it ideal for use in abrasive and refractory applications.
BFA can be used for surface finishing, abrasive blasting, grinding, cutting, and polishing. It is also used for non-slip surfaces, anti-skid flooring, and as an abrasive in the manufacture of grinding wheels.
BFA has various grades and shapes, including grits, powders, and grains. The different grades and shapes are selected based on the application requirements and the surface qualities desired.
BFA has high thermal conductivity, high refractoriness, and high resistance to wear and corrosion. It is an excellent abrasive material for use in harsh environments, high-pressure applications, and high-temperature applications.
The global market for BFA is expected to grow due to its increased use in the manufacturing of automotive, aerospace, and electronic components. The growing demand for surface finishing and the need for abrasives with high durability and cutting ability are some of the factors contributing to the market growth.
