Brown Aluminum Oxide HD

HD 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, HD 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

Brown Aluminum Oxide HDH

It is one kind of Brown Aluminium Oxide grains with blocky grain shape and high bulk density. To get this kind of product, we calcine the regular grains at a high temperature to give a blue colour, the purpose is to renovate the crack on the surface and interior of crystal and then to improve the toughness and durability of the grains.
As an abrasive, the BFA HDH is mainly used in making vitrified and organic bonded grinding wheels for working in heat sensitive metals and alloys.

Process way: High temperature treated;Barmac process

Brown Aluminum Oxide MD

MD 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, MD 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.

Brown Aluminum Oxide AHMCF

AHMCF type aluminum oxide is made by coating the ferric oxide on the surface of the calcined aluminum oxide grains, the result of this kind of processing improve the grain size surface area ratio, hydrophilic ability and grinding efficiency, also the grain toughness improved. AHMCF type is widely used in making premium quality bonded tools, cutting wheel and high load grinding wheels.


Process way: Ferric oxide coated

Brown Aluminum Oxide HDT

It is one kind of specially Brown Aluminium Oxide grain for abrasives application. The lumps that we used to be broken the grain is smelted by the different type of furnace, it is called "tilting furnace". This kind of product have the very small crystal in every abrasives grain, the toughness and anti-impact ability is much better than HD, but the cost is much lower than HDH. It is suitable for making vitrified bonded grinding wheels.
