White fused alumina fine powder 200-0/325
It exhibits excellent chemical stability and boasts outstanding insulating properties. It is particularly well-suited for grinding and polishing precision components, as well as for manufacturing high-grade refractory materials. Moreover, due to the unique characteristics of white fused alumina fine powder itself, it has increasingly become the preferred abrasive material in a growing number of high-end industries.
It has an extremely low coefficient of thermal expansion, excellent hydrophilicity, exceptional toughness, and high strength. Sintered abrasive tools made from this material exhibit a deep blue color after firing, show no network cracks, and remain free of rust stains. As a result, these tools offer enhanced precision and superior grinding performance, making them particularly well-suited for the production of high-grade bonded abrasive tools.

Brown corundum grit, segmental sand, and fine powder
Brown corundum is produced by high-temperature smelting in an electric arc furnace, using bauxite and coke (anthracite coal) as the primary raw materials. Grinding tools made from brown corundum are suitable for grinding metals with relatively high tensile strength, such as various general-purpose steels, malleable cast iron, and hard bronze. It can also be used to manufacture high-grade refractory materials. Brown corundum features high purity, excellent crystal structure, strong fluidity, a low linear thermal expansion coefficient, and excellent corrosion resistance.

Scope of use:
Brown corundum is known as the "teeth of industry": it is primarily used in refractory materials, grinding wheels, and sandblasting.
1. Used for manufacturing high-grade refractory materials, castables, refractory bricks, and the like;
2. Sandblasting—This abrasive material features moderate hardness, high bulk density, zero free silica, high specific gravity, and excellent toughness, making it an ideal “environmentally friendly” sandblasting material. It is widely used in fields such as aluminum profiles, copper profiles, glass, water-washed denim garments, and precision molds.
3. Free Grinding—A grinding-grade abrasive used for free grinding in fields such as cathode-ray tubes, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, jade artifacts, and more; it is a high-end grinding material widely adopted domestically.
4. Resin abrasive tools—featuring appropriately colored abrasives, excellent hardness, good toughness, suitable particle fracture types, and outstanding edge retention—deliver ideal results when used in resin abrasive tools.
5. Coated abrasives—abrasive grains are the raw materials used by manufacturers of sandpaper, cloth wheels, and similar products;
6. Functional fillers—primarily used in automotive brake components, specialty tires, specialized construction products, and other applications—can also serve as wear-resistant materials for constructing highway pavements, aircraft runways, docks, parking lots, industrial flooring, sports venues, and more.
7. Filter media—a new application area for abrasives—uses granular abrasives as the bottom layer of filter beds to purify drinking water or wastewater. This represents a novel type of water filtration material both domestically and internationally, particularly well-suited for non-ferrous metal ore dressing and as a weighting agent for oil drilling mud.
8. Hydraulic cutting—using abrasive materials as the cutting medium and relying on a high-pressure water jet for primary cutting—is a new, environmentally friendly, and safe cutting method applied to the cutting of components such as oil (natural gas) pipelines and steel.
