About BFA:

We Vstake Solution Pvt. Ltd are Manufacturers, Suppliers, Provider, Wholesaler, Trader, Dealer, Exporters of Brown Fused Alumina. BFA or Brown fused alumina is an Alumina Rich Sand which had very high hardness of around 9 Mohs which makes it a great abrasive and very high recyclability. For making of BFA very high quality Bauxite Ores are extracted from the mines. These ores are segregated and calcined upto 1800-2000°C which fuses the entire lot which makes it very stable. This calcined material is then crushed and runned through magnetic separators to remove any unwanted Iron impurity. Brown fused alumina (BFA) is a type of synthetic abrasive material made from the fusion or melting of bauxite (a type of aluminum ore) in an electric arc furnace. It is one of the most commonly used abrasive materials in various industrial applications due to its excellent hardness, toughness, and abrasive properties. Here are some key details about brown fused alumina:

  1. Composition: Brown fused alumina is primarily composed of aluminum oxide (Al2O3) along with other minor impurities and trace elements. The specific composition can vary depending on the manufacturing process and the source of raw materials.
  2. Color: It is called "brown" fused alumina because of its brown or dark brown color, which is a result of the iron content present in the raw bauxite material.
  3. Hardness: Brown fused alumina is known for its high hardness, making it suitable for abrasive applications. It is harder than most other abrasive materials and is commonly used for grinding, cutting, and polishing.
  4. Grain Sizes: It is available in a range of grain sizes, from very fine powders to large abrasive grains or grits. Different grain sizes are used for various applications, including sandblasting, grinding, and surface preparation.
  5. Safety: Safety precautions, including the use of personal protective equipment (PPE) and proper ventilation, are essential when working with brown fused alumina to avoid inhaling dust particles and minimize the risk of exposure to abrasive materials.
  6. Applications:
    • Abrasive Blasting: Brown fused alumina is widely used in abrasive blasting, including sandblasting and shot blasting, to clean and prepare surfaces by removing rust, paint, and scale from metal surfaces.
    • Grinding and Polishing: It is used as an abrasive material in grinding wheels, sharpening stones, and abrasive belts for grinding and polishing applications in the metalworking, woodworking, and glass industries.
    • Coated Abrasives: BFA is used as a coating material for abrasive paper and cloth, allowing for precision sanding and finishing.
    • Refractory Materials:It is used in the production of refractory materials, such as refractory bricks and castables, due to its high temperature resistance.
    • Precision Casting: BFA is used as a material in precision casting processes, particularly in the investment casting of metal parts.
