FEPA P grit,ceramic coating aluminium oixde grain for producing high quality sanding belt,sanding paper,sand cloth,jumbo roll

Description:

AHMCF is a specially treatment blocky, medium bulk density brown fused aluminum oxide abrasive used for resin-bonded wheels to achieve a very strong bond strength. The high temperature heat treatment grain is ceramically bonded with a red iron oxide, this processing can obviously improve the surface area ratio and hydrophilic ability of the grain, and make the grain bond more intimately with phenolic resins. AHMCF can surely improve your bonded wheels grinding efficiency and working life.

Applications:

AHMCF is widely used for making various range of premium quality resin-bonded wheels like cut-off wheels, depressed center wheels and heavy duty wheels.
