（code：WAB）
Characteristic:
It has high hardness and the grains are distributed regularly. Good dispersibility and adsorbability ensure uniform and efficiency of the processing.
The particles powder have certain form of crystal lattice. They become sharp edges when breaking that enhance the efficiency of polishing.
Applications：
Bearings and Steel balls
Particle size：
JIS Standard(Japan):
