Brown Fused Alumina is an important synthetic Fused Alumina refractory mineral made from reduced fusion of quality bauxite iron and coal in a electric arc furnace under 2500 degrees.

Our Brown Fused Alumina is a high grade refractory material with high purity, high cleanliness, low magnetic contents, high density, high bulk density, chemical stability, low porosity rate, nice crystal structure, corrosion and acid resistant, so it can be used for ideal material for precision grinding, polishing, water-jet cutting, coating and anti-slipping products.

5-8mm Brown Fused Alumina is a coarse high-hardness abrasive & refractory aggregate with excellent impact resistance, wear resistance and high temperature stability.
Widely used for heavy-duty rough grinding, industrial floor aggregate, refractory castables, sandblasting, and large grinding tools.
