Black cast aluminum oxide uses bauxite, iron oxide raw materials, and other microelements that in turn melt through a tilt arc furnace, ensuring that the entire piece of shaped black corundum is a high-grade product. Low impurity, high grade and stable quality, paving the way for the production of grain size and micro powder sands with moderate rigidity, fine toughness and excellent service performance. It has characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal stability.
1. Resin cutting / grinding wheels. By adding the appropriate amount of black aluminum oxide to the brown aluminum oxide by producing resin grinding wheels, you can improve the life and quality of the incision, and then reduce the cost.
2. Pavement / Floor: Placement of wear-resistant non-slip pavement, bridge, terrace and wear-resistant non-slip floor.
3. Sandblasting: Used as a shot blasting medium to process the surface of the workpiece, cleaning impurities, cleaning pipes, cleaning the body of the ship, cleaning jets of jets, etc. It is also mainly used for stainless steel sandblasting, fabricated metal products, optical glass, and bamboo products.
4. Polishing and Lapping: Black fused alumina is very good at polishing, such as stainless steel tableware, stainless steel surface and high quality workpiece, just barely burn the surface when lapped.
