Brown Fused Alumina

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-17H is mainly used in making vitrified and organic bonded grinding wheels for working in heat sensitive metals and alloys.

Established in the year of 2000, and almost at the same time, our corporation also began to enter the manufacturing field and have been continuously investing to the factories of artificial corundum and silicon carbide . At present, we have been developing to be a leading industry-trade integrated enterprise. Now HRAC owns one joint-venture bauxite mine, one fully invested prodessing plant of artificial corundum , one smelting plant of artificial corundum which are based on the resource backgound of our five bauxite calcine kilns, one silicon carbide smelting plant and 2 joint-venture refractory materials plants. A variety of abrasive products and refractory products can be manufactured by these plants, such as Brown Aluminium Oxide, white fused alumina, silicon carbide, stainless steel fiber, etc. Being a member of the artificial corundum association of CCCMC and a member of China Abrasives Association.
