Sol-gel Alumina abrasive grain Ceramic Alumina grit SG Abrasive grain

SG(Sol-gel) is the ceramic alumina abrasive developed and produced by our company. It’s a composition of sub-micro aluminum oxide and lamellar grain containing rare earth materials. The grain combines unique self-sharpening properties with high hardness and toughness. Ceramic alumina is applied to kinds of bonded abrasive tools with moderate bulk density and nice particle shape. Ceramic Alumina can be used in a wide range of applications and provides the highest performance and a long tool life.

Sol-gel Alumina abrasive grain Ceramic Alumina grit SG Abrasive grain Features:

1. 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.

2. 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.

3. 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.

4. The roughness is double of normal fused alumina,and even higher than zirconia alumina.

5. 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.

6. Small size grinding edges and sharp grinding can avoid tiny crackle on workpiece.
