Black Fused Aluminum oxide

Black Fused Aluminum Oxide uses bauxite, iron oxide raw materials and other microelement aborative smelt by tilting arc furnace, ensuring all the piece shape black corundum are high grade product. Few impurity, high grade and stable quality, which prepares the ground for producing grain size sands and micro-powder with moderate rigidity, fine tenacity and excellent service performance. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.

Application:

1. Resin cutting/grinding wheels.
Adding appropriate amount of black aluminum oxide into brown aluminum oxide when producing resin grinding wheels, it can improve the work life and the incision quality, then lower the cost.
2. Pavement /Floor
Laying wear-resisting antiskid pavement, bridge, terrace, and making wear-resisting non-slip floor.
3. Sandblasting
Used as blasting media to process the surface of work piece, cleaning impurity, pipeline cleaning, vessel body cleaning, Jean cloth sandblasting, etc. It’s also mainly used for sandblasting of stainless steel, fabricated metal products, optical glass, bamboo products.
4. Polishing and Lapping
Black fused alumina is very good in polishing, like stainless steel table ware, surface of stainless steel, and high-grade work piece, hardly burn the surface when lapping.
