Conventional abrasives :
Brown aluminum oxide, hard and tough
Most common used abrasive, especially for heavy-duty grinding on general steels.
Friable aluminum oxide characteristic is between A and WA
Special for precision grinding on alloy steels.
White Aluminum oxide, more friable than A, harder than A
Suitable for light grinding on general and hardened steels.
Mixed abrasive of A and WA.
Precision grinding on alloy steels of low hardness.
Mixed abrasive of WA and FA
Precision grinding on alloy steels of medium hardness
Chrome aluminum oxide, tougher than WA
Precision or large surface grinding on hard alloy steels and tool steels.
Zirconia aluminum oxide, tougher than PA
Good self-sharpness characteristic, suitable for precision grinding.
Monocrystalline aluminum oxide, hard and tougher than WA, good self-sharpness characteristic
Precision grinding of high hardness tool steel and stainless steel
Mixed abrasive of WA and RA
Mainly used for hardened steel and stainless steel
Ceramic aluminum oxide/ micron crystalline aluminum oxide. Micro angular shape, durable
Efficient grinding, and cut, lesser abrasives consumption.
Natural compound of alumina and ferrite
Good for hydraulic cutting and sandblasting
Black silicon carbide, harder and more friable than WA
Suitable for non-ferrous metal, rubber, plastic, ceramic, glass, and stone.
Green silicon carbide, harder and more friable than C
Suitable for non-ferrous metal, rubber, plastic, ceramic, glass, stone and carbide tools.
