WHITE FUSED ALUMINA FOR BONDED AND COATED ABRASIVES
DESCRIPTION
White fused alumina is a kind of artificial corundum, with Al2O3
99% Min., HS code 2818109000
By application, it can be divided into:
- F sand for Bonded Abrasives, sandblasting, polishing
- P sand for coated Abrasives
- Section sand for refractory
The particle size can be produced according to China GB/T, FEPA,
JIS, ANSI, etc, and can be processed according to the user's
required particle size.
The general particle size number is F4~F220.
The outstanding feature is that the crystal size is small and good
impact resistant. The grit surface is dry and easy to combine with
the binder.

APPLICATIONS
White aluminium oxide abrasive is suitable for:
Sandblasting
Surface beautification of various high-end products, crafts or
hardware products.
After blasting, the surface is white and free of any impurities,
eliminating the need for cleaning troubles.
Polishing
Fine white corundum can be used as the first polishing.
Bonded Abrasives
Grinding wheels, straight cut-off wheels and depressed center
wheels, cutting discs, mounted points, sharpening stone, cones &
plugs, etc.
Coated Abrasives
Sanding rolls, sanding sheets, sanding belt, sanding disc, flap
disc, flap wheel, spiral bands, cartridge rolls, etc.
Refractory materials
Refractory bricks, castables, etc.
