Brown Fused Alumina is produced by fusion of calcined bauxite in an electric arc furnace at over 2000 centigrade.It stands out due to very high toughness so that it has a long lifespan but cool cutting is not expected.By these characters,it widely use for working on regular steel,carbon steel,forging steel,ingot steel and cast iron,malleable iron as well as some non-ferrous metals.

Chemical composition%(Grit 36)

Particle size distribution

F8–F1200 are available,PSD according to FEPA standard 42,GB/T 2481.

JIS standard or ANSI standard or customer’s specific required is also available.

Bulk Density(g/cm3)

Bulk Density is a typical index to express the shape different.

RUNBAO divide regular brown by different grains shape in two types AF10 and AF20.AF10 has blocky shape with high impact resistance and AF20 has angular shape with sharp cutting edge.So that AF10 has higher toughness and AF20 has higher cutting quality.

Medium shapes(Bulk density between AF10 and AF20)are also available under customer special requirements.
