Brown corundum (A) contains 95% baiAL2O3, SiO2: 1.2%; TiO2: 3%; Fe2O3: 0.3%, etc.Brown-brown du, the product has high hardness and toughness. The abrasive tools made from it are used for grinding carbon Zhuan steel, general alloy shu steel, malleable cast iron, hard bronze, etc.
White corundum, containing 99.5% AL2O3, Fe2O3: 0.5%.The hardness is slightly higher than that of brown corundum, and the toughness is slightly lower. The abrasive tools made of it are used for grinding high carbon steel at high speed.Steel and stainless steel, fine-grained abrasives can also be used for precision casting and refractory materials.
Pay attention:White fused alumina is more expensive than brown fused alumina.
The characteristics of brown corundum products bai: Due to the advantages of mineral properties, it has higher hardness, better toughness, higher specific gravity, and no harmful substances than du products. Brown corundum products are a natural environmentally friendly grinding material. It has played an important role in the international blast cleaning industry. As a grinding medium, it accounts for 45% of industrial consumption. It can be seen that brown corundum products are more and more recognized in the blasting industry. Brown fused alumina products are an emerging application material advantage in the application field of abrasives industry. Among various spray abrasives, the advantages of brown fused alumina products mainly include:
What is the difference between the grinding wheel of brown corundum products and the grinding wheel of white corundum products? Brown corundum products are suitable for ordinary grinding of alloy copper, carbon copper, and forgeable copper workpieces with lower hardness, such as cylindrical grinding and surface grinding It can also be used for cutting, grinding and so on. White corundum products are used for ordinary grinding of high-speed copper, alloy copper, and quenched copper workpieces with high hardness. It is also used in some industries of gear grinding, thread grinding, and profile grinding. The difference between the grinding wheels of brown corundum products and the grinding wheels of white corundum products is actually the difference in the abrasives used by the two. Brown corundum products have high toughness and are suitable for grinding on metals with high tensile strength such as ordinary rigid, malleable cast iron, hard bronze, etc., and can also be made into refractory materials. The hardness of white corundum products is similar to that of brown corundum products, and the cutting ability is better than that of brown corundum, and the toughness is slightly lower, which is suitable for fine grinding and fine grinding of hardened steel and alloy rigid materials.
Resin grinding wheel is a grinding wheel made of resin with high strength. It is used in cutting discs, double end faces, heavy-duty grinding wheels, polishing wheels and so on. It has certain elasticity, low heat resistance, good self-sharpening, easy production, and short process cycle; it is widely used for rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc. Brown corundum and White corundum are very important materials of resin grinding wheels.
