General Products

White fused alumina is smelting in a electrical arc furnace from aluminum oxide powder. The colour is white, the hardness and toughness is higher than brown fused alumina, The grinding tools made of it are suitable for fine grinding of high carbon steel, stainless steel and high speed steel.
The grains of this type has equaled volume grain shape and high bulk density. It can be used for different grinding abrasives applications.
