F#30/36 Fused white Al2O3 alumina sand abrasives for cutting disks
Product Description
Fused white Al2O3 alumina sand was 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 alpha-Al2O3. White sand abrasives produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
