Description

Product Detail

Calcined Alumina powder for polishing:

Using a unique production process, the use of advanced production equipment at home and abroad, through rigorous production processes made. The product has the following superior performance:
? crystal phase stability, high hardness, small particles and uniform distribution;
? grinding power, polishing fast, bright light, the mirror effect is good;
? high grinding efficiency, good polishing effect, grinding efficiency is much higher than that of soft abrasive such as silica, the surface finish is better than that of white corundum, strong cutting force, fast light, can throw a uniform and bright
