Semi-friable Brown Fused Aluminum Oxide ( Bonded Abrasives )

Semi-friable Brown Fused Aluminum Oxide ( BondedAbrasives )

TYPE: SEMI-F

1. Application

Widely adopt byresinoid and vitrified bonded grinding wheels working for heat sensitive metalsand alloys and soft non-ferrous metals etc… applied cooler grinding.

2. Description:

Produced by Higgins electric arc furnace bycontrolled fusion and slow solidification. The reduced titanium oxide contentsand increased aluminum oxide contents provide the grains with medium toughnessand hardness between white corundum and regular brown corundum. So it has excellenceremoval rate and tool life.

The grains were calcined,the crystal surface and interior micro-crack or stress can be recovered, thenthe grains strength and hydrophilicity improved much.

Blocky grains shape with heavily mulled edges and stable bulk density.

Repeatedly magnetic separation reduced make the grains could bealso directly use for vitrified wheel application.
