artifical corundum AF-01A

The brown aluminum of this type, the lump is broken up by BAMARC machine and the grain shape is blocky and edge sharp. It has higher density, and the tools made of it have the higher grinding efficiency. The bust collecting way of this kind of product is by water washing. The clean grains is easy to be bonded and do no harm to the workers health during abrasive tools be made. It is the excellent vitrified abrasive grain.
