Brown Brown fused alumina for bonded abrasive(AE-17H)

Description

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 AE**7H is mainly used in making vitrified and organic bonded grinding wheels for working in heat sensitive metals and alloys.
