Brown Fused Alumina

Brown fused Alumina known as “artificial corundum” or “alumina grit” is manufactured by fusing high-grade bauxite in electric arc furnaces.  This fused mass is crushed and sized to meet its application requirements – FEPA sizes for bonded and coated abrasives, and grains for refractories.

Key attributes: 
Hardness (Mohs 9) & toughness
Dimensional thermal stability

Key applications:

  • Refractory products
  • Grinding media
  • Anti-slip flooring

Abrasive Application of Fused Alumina

We offer a range of products for bonded and surface coated abrasives – brown fused alumina (P and F grades), standard, high density and calcined brown fused alumina, white fused alumina, pink fused alumina, silicon carbide, boron carbide and cubic boron nitride.  A range of refractory plates used in the production of vitreous bonded abrasive wheels are now available to order.

Brown fused alumina has the quality of self-sharpening by fracturing to leave fresh needle-sharp surfaces in use.  Microgrit brown fused alumina sizes are now available for manufacture of precision abrasive tools.

We have identified and qualified a small number of partner producers in China and work closely with them to ensure consistency of the material.
