Product Description
Black Aluminum oxide blasting media Top Quality Al2O3 80% Min.
Black aluminum oxide is a new alternative abrasive, it is mainly divided into two grades, ordinary grade and top-quality grade. The ordinary grade Al2O3 content is 62% min., and the Top-quality grade Al2o3 content is 80% min.
Top quality black aluminum oxide is harder than ordinary black aluminum oxide, with similar hardness as Brown aluminum oxide, and is mainly used for high-grade sandblasting and polishing. The newly developed black aluminum oxide top-quality P sand is a new type of abrasive for producing sandpaper and abrasive belt.
