Brown Aluminum Oxide is also called brown fused alumina,Brown corundum,made from Calcined Bauxite. It is a hard and tough material, used in grinding wheels manufacturing (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media.
Zhengzhou Haixu Abrasives Co.,ltd,as a manufacturer of brown aluminum oxide from China,has produced it for more than 24years.
About the sizes we produce macrogrit including F12 F14 F20 F22 F24 F30 F36 F46 F54 F60 F70 F80 F90 F100 F120 F150 F180 F220 and micropowder including F230 F240 F280 F320 F360 F400 F500 F600 F800.
