Flap Disc Solid Aluminum Oxide
Black aluminum oxide P sand for Coated Abrasives of Abrasive belt, flap disc Black aluminum oxide, also known as low-aluminum corundum, is a black gray crystal with α-Al2O3 and iron spinel as the main ore phase, produced by melting aluminum bauxite in an electric arc furnace, which is characterized by low Al2O3 content. There is a certain amount of Fe2O3 (about 10%), so it has the characteristics of moderate hardness, high toughness, high temperature resistance and stable
Black aluminum oxide P sand for Coated Abrasives of Abrasive belt, flap disc
Black aluminum oxide, also known as low-aluminum corundum, is a black gray crystal with α-Al2O3 and iron spinel as the main ore phase, produced by melting aluminum bauxite in an electric arc furnace, which is characterized by low Al2O3 content. There is a certain amount of Fe2O3 (about 10%), so it has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance.
There are F sand and P sand. F sand mainly used for bonded abrasives like cutting discs, sandblasting, etc.
P sand maily used for Coated Abrasives like Abrasive belt, flap disc, Fiber Wheels, etc.
