D50 Value of brown aluminum oxide powder FEPA,JIS,P,W standard
Brown aluminum oxide,also called brown fused alumina BFA,brown corundum etc, is 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,founded in 1999,has been manufacturing and exporting abrasives for more than 20 years from China.Our factory mainly produce brown aluminum oxide,white aluminum oxide and silicon carbide.
About brown aluminum oxide,we mainly produce grit and powder.
For grit,no matter produced under which standard,they are PSD is almost same,but for powder,different standard,has big difference.
Today just conclulate the D50 of brown aluminum oxide powder which are produced under different standard as follows:
