BROWN CORUNDUM #240 D50:57.0±3.0UM
Brown corundum is also known as brown fused alumina,brown aluminum oxide,brown electrocorundum,brown emery sand,electrocorundum 14A etc; for short “BFA” or “A”.
It is made from Calcined Bauxite. It is a hard and tough material, used in grinding wheels manufacturing and coated products.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been manufacturing and exporting brown corundum for more than 20years,we mainly produce the following grits:
