Ceramic alumina grain F24 F30 F36

Introduction of Ceramic alumina grain F24 F30 F36

Ceramic Alumina abrasive grain is featured for its extream tiny crystal size and durability.It is also be called SG abrasive grain or ceramic alumina. Ceramic alumina grain is made by a sol-gel method instead of fusing process. The main structure of ceramic alumina grain is

α-Al2O3. White color and blue color sol-gel alumina grains are made from different seeded formulas. The white one is of higher aluminum oxide purity. And white color is more suitable for vitrified boned abrasive wheels.

The features of Ceramic alumina grain F24 F30 F36

Small crystal size about 100-150nm, which is even much smaller than zirconia alumina. And it’s hundredths of the size of normal fused alumina grains.So it will make abrasive wheels increase lifetime by several times than ordinary wheels.
Excellent self-sharpening performance. The sol-gel grain will get new grinding edges after grinding. The edges are get from the single grain crystal instead of off a whole crystal. That makes the grain much sharper than normal fused alumina.
The microscopic hardness of sol-gel alumina is about 1900-2400 kgs/cm2,which is higher than zirconia alumina. Thus,sol-gel alumina can make grinding and cutting easier for special hard metal such as Nickel chromium alloy and nickel titanium alloy.
The roughness is double of normal fused alumina,and even higher than zirconia alumina.
Low temperature grinding is another significant property of Sol-gel alumina abrasive grain. That will avoid much heat during grinding and cutting, so it won’t get hurt of workpiece surface.
Small size grinding edges and sharp grinding can avoid tiny crackle on workpiece.
