AE-17HM

It is one kind of Brown Aluminium Oxide grains with blocky grain shape and high bulk density. To get this kind of product, we treat the regular grains at a medium high temperature to give a light 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 AE-17HM is mainly used in making vitrified and organic bonded grinding wheels. The cost of AE-17HM is more economic than AE-17H.
