0-1mm brown corundum 1-3mm brown fused alumina 3-5mm aluminum oxide
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 is utilized 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.
