Product name |
Black alumina oxide, black corundum abrasive, black silicon carbide |
|
Brand name |
BA,CHINA |
|
Description |
Silicon carbide is made of quartz sand, petroleum coke(or char), the sawdust as raw materials by high temperature smelting in resistance furnace. |
|
Advantage |
Having sharp knife-edge.. Electrical conductivity, thermal conductivity Capable of metal removal Highly friable abrasive media which is reusable but less durable than brown aluminum oxide Cleaning or etching the hardest sub-surfaces May be required for some applications that require brazing or welding after blasting Used for grinding, lapping, and wire saw cutting as well as abrasive blasting |

Parameter |
Shape: Polygon Maximum operating temperature (℃) : 1850 Hardness (Mohs) : Min.9 Melting point (℃) : 2050 Linear expansion coefficient (0-1600 ℃) : 7-9 True density (g/cm3) : Min.3.5 Color: Black Packing: 25 kg Composition% : Al2O3:77-88 TiO2:2-4 SiO2: 5-8 Fe2O3:6-9 |
|
Usage |
Black corundum is mainly used in free grinding, such as the underside polishing of metal parts before electroplating, aluminum products, suitable for bicycle, motorcycle, sewing machine, watch parts, lighting, plastic and hardware tools polishing, also suitable for sandblasting (rust removal, glass spray), processing materials, manufacturing resin cutting pieces, Angle grinding pieces and coated abrasive tools. Black corundum grit sand and micropowder are especially suitable for grinding and polishing of stainless steel workpiece and manufacturing of whetstone and grinding paste. Black corundum segment sand is the preferred material for anti-skid pavement and underground coal mine storage. Removal of metal oxide layer, carbide black, metal or non-metallic surface rust removal
