Brown Fused Alumina is a dense material produced from bauxite raw material. The end product has a low iron content making it particularly valuable in refractory applications.

Brown fused alumina uses

Refractory & Foundry

Brown Fused Alumina is utilised within the refractory industry for the manufacture of high alumina fired and monolithic refractory products like bricks, pre-cast shapes and also foundry applications, where the addition of Brown Fused Alumina helps to obtain a smooth surface finish in investment castings.

Sizes Available: 0-1mm,1-3mm,3-5mm,5-8mm,8-12mm,100mesh,200mesh,325mesh etc

Abrasives

Within the abrasive industry Brown Fused Alumina is a valuable addition to products like abrasive papers and in shot blasting applications.

Sizes: FEPA F8-F220

Brown Fused Aluminium Oxide finer grades are ideal material for precision grinding, polishing, water-jet cutting, coating and anti-slipping products etc. It’s also called Brown Fused Alumina Fines or Powder.
