WHITE FUSED ALUMINA F80
White fused alumina is also known as white corundum,white aluminum oxide,white electrocorundum,white emery sand etc,for short”WFA” or “WA”.It
made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase α-Al2O3.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been manufacturing and exporting white fused alumina for more than 20years,we mainly produce the sizes of white fused alumina:
