Brown Aluminium Oxide F Series

Brown fused alumina is produced on the FEPA standard with the characteristics of standard particle size, good cleanliness, high bulk density, strong self-sharpening, good toughness, high strength, and low content of magnetic materials.

The grinding tools made of it have strong grinding force, low heat generation, high grinding ratio, and small adhesion in use, dark blue in color, without surface cracking or rust spots.
It is mainly applied in manufacturing vitrified and resin bonded abrasive wheels, sand blasting, grinding, polishing etc.
