About Brown Fused Aluminum Oxide

Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.

Because Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage. 

Additionally, BFA has a low friability which allows it to be recirculated on average, up to seven times. These characteristics reduce abrasive consumption, clean up, and disposal costs, increasing profitability.

Brown Fused Aluminum Oxide Applications

Brown fused aluminum oxide is the most widely used abrasive due to its many applications. Its versatility lends itself to the following uses:

  • Anti-Skid – BFA grains are added to fresh concrete, paint, and bonding to surfaces using adhesives and resin cements in order to help prevent vehicle skidding.
  • Anti-Slip – Like the anti-skid methods, BFA grains are added to the surface material that is used in high traffic areas to prevent pedestrians from slipping.
  • Blasting Media – BFA can be used as a blasting media that is used to prepare and clean surfaces prior to coating.
  • Bonded Abrasives – BFA is used to make bonded abrasives like cutting-off and grinding wheels, snagging wheels, mounted wheels, segments, honing stones, plugs, cones, etc.
  • Coated Abrasives – BFA is used to make coated abrasives such as sandpaper and are available in sheets, discs, rolls, belts, pads, flap wheels, and other forms.
  • Coatings – BFA is often used as an additive to coating mixes to provide added protection against corrosion, wear and abrasion.
  • Pressure Blasting – Blasting is used to clean, polish, cut, or finish surfaces. It is done by propelling media against surfaces using high-pressured blasting cabinets or blasting guns. Blasting can be done with a wet or dry process and is available in numerous grit sizes.
  • Refractory – BFA has hundreds of applications as a refractory material due to its ability to withstand continuous exposure to the combination of heat, corrosion, abrasion and impact.
  • Surface Preparation – BFA is used as a finishing media for cleaning and surface preparation products.

For the abrasive market, brown fused aluminum oxide is available in the following ANSI sizes 8 – 240 grit.
