Brown Aluminum Oxide (BFA) is produced by the fusion of high-quality bauxite in an electric arc furnace at high temperatures. Our Brown Aluminum Oxide has high compression strength, high toughness, excellent self-sharpening, low coefficient of thermal expansion, and excellent hydrophilia and cleanliness.brown fused alumina manufacturer It is a clean, high-strength material that resists oxidation and corrosion, maintains chemical stability, and withstands extraordinarily high temperatures.
Brown Fused Alumina is a dense material produced from bauxite raw material which is fused in an electric arc furnace. This product is from a high quality consistent Chinese source. The end product has a low iron content making it particularly valuable in refractory applications
Brown Fused Alumina is fused with premium rawmaterials and 3500 KVA furnace. It is perfect material specificallymanufactured to be used for general abrasive applications in bonded abrasivetools, and lapping and polishing processes. While aluminum oxide has lowerhardness and abrasive capacity than diamond, boron carbide, and silicon carbide,it is widely used for grinding ferrous materials, finishing tough and hardmaterials. It is also be used as high-class refractory materials. Brownaluminum oxide is offered in macro and micro powder form, in both F and Pgrades.
Calcined Brown Aluminum Oxide: Heating to 1050°C greatly improves the purity, toughness, strength, and wear-resistance of abrasives. Primary application: vitrified grinding wheels.
Blue-Fired Brown Aluminum Oxide: While turning grain-color dark blue, firing at 1350°C achieves far greater toughness and strength, much lower iron content, a very low coefficient of thermal expansion, and excellent hydrophilicity, all of which increase grinding performance and accuracy. Primary applications: coated abrasives (paper, cloth and belts) and heavy-duty grinding wheels.
Ceramic-Coated Brown Aluminum Oxide: Ceramic coating improves purity and hydrophilicity, reduces dust, and achieves grain surfaces that have greater toughness, strength, and roughness, and that are also more uniform in particle size. Primary applications: coated and bonded abrasives.
Ceramic-Coated Blue-Fired Brown Aluminum Oxide: These grains deliver all of the advantages of both Ceramic-Coated and Blue-Fired BFA. corundum wholesale Primary application: coated and bonded abrasives, especially those for use on hardened steel and other high-carbide materials.
