Brown fused alumina is produced from bauxite and coke (anthracite) through high-temperature smelting in an electric arc furnace. The abrasives made from it are suitable for grinding metals with high tensile strength, such as various carbon steels, malleable cast iron, and hard bronze, and can also be used to manufacture refractory materials. Brown fused alumina boasts high purity, good crystallinity, strong fluidity, low coefficient of linear expansion, and corrosion resistance. After being tested by dozens of refractory material manufacturers, this product has been proven to be non-explosive, non-pulverizable, and non-cracking during use. Particularly, its superior cost-performance ratio compared to traditional brown fused alumina makes it the ideal aggregate and filler for brown fused alumina-based refractory materials.

Brown fused aluminum oxide application range

Brown fused alumina is known as the "teeth of industry": mainly used in refractory materials, grinding wheels, and sandblasting.

1. Used for manufacturing refractory materials, castables, refractory bricks, etc.

2. Sandblasting - with moderate abrasive hardness, high bulk density, no free silicon dioxide, high specific gravity, and good toughness, it is an ideal "environmentally friendly" sandblasting material, widely used in aluminum profiles, copper profiles, glass, fine molds for water-washed denim clothing, and other fields.

3. Free Grinding - Free grinding abrasive, used in the fields of cathode ray tubes, optical glass, single crystal silicon, lenses, glass for watches, crystal glass, jade products, etc., is a widely used grinding material in China.

4. Resin Abrasive Tools - The abrasive features suitable color, good hardness, tenacity, appropriate particle cross-section type, and edge retention, which are ideal for use in resin abrasive tools.

5. Bonded Abrasive Tools - Abrasive materials such as sandpaper, cloth, etc., are the raw materials for manufacturers of abrasive products.

6. Functional Filler - Primarily used in automotive brake parts, special tires, and special construction products, suitable for road construction of expressways, airport runways, docks, parking lots, industrial floors, and sports fields, etc., as wear-resistant materials.

7. Filtration Media – A novel application of abrasive materials, using granular abrasives as the bottom layer medium for the filtration bed, to purify drinking water or wastewater. It is a new type of water filtration material both domestically and internationally, particularly suitable for non-ferrous metal ore beneficiation: oil drilling mud weighting agent:

8. Hydrocutting - Utilizes abrasive as the cutting medium, relying on high-pressure water jets for basic cutting. It is applied to the cutting of oil pipelines, steel components, and other parts, representing a new, environmentally friendly, and safe cutting method.
