Alumina fusa marrone
Alumina fusa marrone
Alumina fusa marrone, or BFA, is a material produced from high-quality bauxite and other raw materials. It is manufactured through a complex process of fusion in electric arc furnaces at high temperatures. The resulting material is a hard and tough abrasive that is suitable for a wide range of industrial applications.

Introduzione
Alumina fusa marrone (BFA) is a tough, durable, and highly versatile abrasive material that can help you tackle even the toughest industrial grinding and polishing applications. Made from high-quality bauxite, BFA is fused and cooled under carefully controlled conditions, resulting in a product that is exceptionally hard and wear-resistant. Its unique combination of hardness, toughness, and sharpness makes BFA ideal for a wide range of applications, from surface preparation to metalworking, woodworking, and more.
Brown fused alumina is classified based on its chemical composition and crystalline structure. It is classified into two types – regular and low iron. Regular brown fused alumina contains 1-3% iron, whereas low iron brown fused alumina contains less than 0.2% iron.
A Henan Superior Abrasives, we offer the highest quality Brown Fused Alumina to meet your industrial needs. With its superior hardness, toughness, and density, BFA is the perfect abrasive for a wide range of applications. Trust us to provide you with the best possible abrasive solution for your business.
Advantages
Alta durezza
Brown Fused Alumina has a Mohs hardness of 9, making it one of the hardest abrasives available in the market. This characteristic ensures that it can withstand the toughest applications and provide consistent results over time.
High Toughness
Brown Fused Alumina has excellent toughness, which allows it to resist fractures and breakage. This toughness also makes it suitable for high-pressure applications that require a strong abrasive.
High Density
Brown Fused Alumina has a high density, which ensures that it can cut through tough materials quickly and efficiently. This density also helps to reduce the amount of dust generated during the cutting process, making it a cleaner and safer abrasive to use.

Applicazioni
Grinding and Polishing
BFA is an excellent abrasive for grinding and polishing applications. It is used in the manufacturing of grinding wheels, honing stones, and other abrasive tools.
Sandblasting
BFA is widely used as a sandblasting abrasive due to its high hardness and toughness. It is suitable for removing rust, paint, and other surface contaminants from metal surfaces.
Materiali refrattari
BFA is also used in the production of refractory materials, such as firebricks, due to its high melting point and resistance to heat.
