Detailed information

Brown Aluminum Oxide

Type: AE-17

AE-17 is a kind of regular Brown Aluminum Oxide abrasive grains, the shape of the grain is angular and edge sharp with the medium high 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-17 is mainly used in making vitrified bonded grinding wheels. As loose grains, it is widely used for pressure blasting, surface finish and other general industrial applications.
