Product Details
Aluminum Oxide Blasting Media Black Fused Alumina F12-F220 for
Polishing Stainless Steel Tablewares
1. Product Description of Black Fused Alumina
Black Fused Alumina belongs to the group of electric corundum,
Different from the second quality grade
brown fused alumina, black fused alumina is one artifical corundum
made by specially. It is widely used
for making resin cutting discs and coated abrasives mixed with
brown fused alumina.
In addition,it is also widely used for polishing stainless steel
tablewares to achieve the uniform visual effect.

4. Why Black Aluminum Oxide is suitble for polishing stainless
stell tablewares?
Moderate hardness and good self-sharpness,which will generate
little heat in polishing process,it will not
burn the treatment surface and finally achieve the uniform and
bright color.
