WHITE CALCINED ALUMINA POWDER
White calcined alumina powder here means a special abrasive powder which is calcined from aluminum oxide with plate-shape.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,mainly produce white fused alumina,which is used for blasting,grinding and polishing etc,recent years,to meet with customers’requirement,we built our production line to produce white calcined alumina,which is similar to Japan Fujimi PWA and USA microgrit WCA.
The specification of our white calcined alumina powder is as follows:
