Sell regular brown aluminum oxide abrasive grains ae-20 @China (Mainland)

AE-20 is a kind of regular Brown Aluminum Oxide abrasive grains, the shape of the grain is angular and edge sharp, combined with blocky grain shape and sharp grain shape. With the medium loose bulk density. To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes. As an abrasive, AE-20 is mainly used in making organic bonded grinding wheels, resign bonded grinding wheels and polishing stones. As loose grains, it is widely used for pressure blasting, surface finish and other general industrial applications.
