Description

Brown Fused Alumina is made from calcined bauxite. it is hard and tough material. Brown fused alumina can be used for both as abrasive material and refractory material according to its Al2O3 content. BFA products are well applied in sandblasting, polishing, refractory bricks and pottery sector.

Features of Brown Fused Alumina

High hardness, crystallinity, good fluidity, little adhesion, no detenate, crack, and pulverization during use . The calcined abrasive tool is dark blue in color, without mesh cracks and rust spots.

Produce Processing

Raw material sorting→electrolysis smelting→crushing→magnetic separation & deironing→screening→physical & chemical inspection
