Brand Name: haixu
Model Number: F-macrogrit
Place of Origin: Henan, China (Mainland)
Product Introduction-white aluminium oxide sandblast
Name-white aluminium oxide sandblast
Size standard-FEPA
color-white,semi-invisible
Grain shape-angular
White aluminium oxide sandblast grit was made from the high quality alumina by melting above 2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alpha Al2O3.
The white aluminium oxide sandblast grit 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.
