CHEMICAL,PROPERTIES AND SIZES OF BROWN ALUMINUM OXIDE
Brown aluminum oxide is also known as brown fused alumina,brown corundum,brown fused aluminum oxide,electrocorundum 14A,emery sand etc.
It is made from calcined bauxite with mohs hardness 9.0.
Zhengzhou haixu abrasives co.,ltd,main producer of brown aluminum oxide from China,founded in 1999,has been producing and exporting brown aluminum oxide from more than 20years.
Our brown aluminum oxide factory own 12000 square kilometers,and produce different grades of brown aluminum oxide.
Today we only introduce our A grade brown aluminum oxide.
