Semi-friable fused alumina is a new type of high-end electric fused corundum, which is made from high-quality bauxite as raw material. Based on the smelting of sub white corundum, the smelting process and ratio are adjusted. After being melted at high temperatures above 2100 ℃ in an electric arc furnace, it is processed using special crushing processing technology. 

It combines the merits of brown fused alumina (A) and white fused alumina(WA), with brittleness and toughness between with A and WA.It has advantages such as good self sharpening, high temperature resistance, corrosion resistance, erosion resistance, low porosity, and stable thermal performance. Sharp grinding without easily burning the workpiece.

The bonded abrasive which manufactured with it provides a higher durability, good sharpness and retentiveness. While processing somework pieces under the same conditions, it demonstrates better surface quality, higherprocessing efficiency and better durability of grinding tool than brown, white, chromeand monocrystalline fused alumina.

Used for rough grinding, it can improve the processing efficiency and used for accurate grinding. It can improve thesurface quality of work piece.

Application：

With the unique grindingand cutting effect, it can be used for manufacturing high grade ceramic, resin grindingtools and coated abrasive tools.

Especially suitable for grinding heat-sensitive steel and alloys, low hardness non-ferrous metal materials such as aluminum, copper, zinc, lead, and non-metallic materials such as wood and plastic.
