White Aluminum Oxide(WA)
White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, Abrasive powder of finer grit size can also be used for precision casting and high-grade refractory.

Brown Aluminum Oxide(A)
Brown aluminum oxide abrasive electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown color, high hardness and great toughness. The abrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel malleable cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc.

PINK ALUMINUM OXIDE(PA)
Pink aluminum oxide, its hardness is close to, but toughness higher than that of WA. The abrasive tools made of it feature excellent durability and high processing cleanness, which are suitable for the precision grinding of the measuring tools, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc.

HIGH PURE FUSED ALUMINUM OXIDE(HA)
It is as hard as white aluminum oxide, as tough as brown aluminum oxide. It is a kind of high-grade refractory and grinding materials, the specific gravity 3. 9g/cm3, the degree of refractory 1850.

BLACK ALUMINUM OXIDE (BA)
With high toughness, black aluminum oxide is extremely suitable for polishing stainless steel and non-ferrous metals. It's grinding efficiency is much higher than that of brown A/O and the finishing effect is much better than many of other abrasive materials.

ZIRCONIA ALUMINUM OXIDE (ZA)
Especially suitable for snagging billets of stainless steel, carbon steel, alloy steel, etc.

SINGLE CRYSTAL ALUMINUM OXIDE (SA)
It is used to grind stainless steel, high-speed steel and heat sensitive steel.

GARNET
The specific gravity of garnet is 3.96
