Black Aluminum Oxide Blast Media Wholesale Price

The brown fused alumina price is mainly used for free grinding. The black corundum is made of high-quality bauxite as the main raw material, adding less reducing agent and smelting in high temperature in the electric arc furnace. The color is black with moderate hardness. Characteristics of green carborundum: the product granularity is produced according to international standards and national standards, and can be processed according to the granularity required by users.

Its toughness is large, wear-resistant, sharp edges and corners, self sharpening is strong, grinding has less heat, polishing workpiece has high cleanliness, the basic material of white aluminium oxide abrasives is concentrated, cutting force is strong, toughness is large, and rigidity Soft, wear-resistant, high efficiency. The technological process of silicon carbide companies is as follows: corundum block - coarse crushing - medium crushing - crushing - segmented screening - magnetic separation - fine screening - Inspection - packaging.


For example, before the electroplating of metal parts, the bottom surface polishing and pink corundum products are suitable for the polishing of bicycles, motorcycles, sewing machines, clock parts, lighting, plastics and hardware tools, as well as sandblasting (rust removal, glass spray), processing materials, resin cutting pieces, angle grinding pieces and coated abrasives. There are two kinds of density, one is the accumulation density of aluminum oxide grit, the other is the true density of white corundum.


Smelting method of white corundum: Bauxite trihydrate is used as raw material, a small amount of reducing agent is added, and the power consumption is about two-thirds of that of brown corundum. The specific gravity of black corundum production process shall not be less than 3.61. Black corundum is a common abrasive in our production and life. It is mainly used for stainless steel kitchenware, lamps and lanterns, motorcycle parts and so on.


The general particle size is from F4 to F320, and its chemical composition depends on the brown fused alumina particle size. It is black mainly because of its unique use advantages: high hardness, high toughness, good adhesion and hydrophilicity, less heat, strong self sharpening, high work efficiency and high finish. The basic particles are concentrated, the cutting force is strong, the toughness is large, the hardness and flexibility are combined, the 46 grit aluminum oxide wear resistance is good, and the work efficiency is high.


The silicon carbide abrasive hardness is moderate, the toughness is large, the wear-resistant edges and corners are sharp, the self sharpening is strong, the heat generated in grinding is small, and the cleanliness of polishing workpiece is high. White corundum has the characteristics of large volume density, low porosity, good volume stability and thermal shock resistance. It is a high-grade refractory raw material with good effect. With the improvement of aluminum oxide blast media 60 grit product quality, the application scope is still expanding.


The brown aluminum oxide main chemical composition is: Al2O3 is not less than 77%, SiO2 content is 10-12%, Fe2O3 content is 7-10%, TiO2 is about 3% corundum, which is suitable for manufacturing ceramics, resin bonded abrasives, grinding, polishing, sandblasting, precision casting (special corundum for investment casting), and also for manufacturing high-grade fire-resistant materials. White, harder and crisper than brown corundum, strong cutting force, good chemical stability, white corundum features good insulation.
