Product Description

Product Description

Brown aluminum oxide bfa brown fused alumina for wear resistant coating
 

is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.

Application Scenarios

1. Grinding and Polishing: White fused alumina grits are widely used in grinding and polishing applications. They are used in the manufacturing of abrasive wheels, belts, and discs for precision grinding of metals, ceramics, and composites. The sharp and angular grains provide efficient cutting action and consistent surface finishes.

2. Surface Preparation: White fused alumina grits and sand are commonly used for surface preparation in industries such as foundries, metal fabrication, and shipbuilding. They are suitable for removing scale, rust, paint, and other surface contaminants from metal substrates, providing a clean and prepared surface for subsequent coating or bonding processes.

3. Refractories: Due to its high melting point and excellent thermal stability, white fused alumina is extensively used in the production of high-quality refractory products. It is used as a raw material to manufacture firebricks, refractory castables, and other shaped or unshaped refractory products. These are widely utilized in high-temperature industries such as steel, cement, and glass manufacturing.

4. Precision Casting: White fused alumina powder is used as a precision casting material. It is mixed with a binder and applied in the production of investment casting molds or cores, resulting in high-dimensional accuracy, smooth surfaces, and improved casting quality.

5. Abrasive Blasting: White fused alumina grits and sand are utilized in abrasive blasting operations. They are commonly used for surface cleaning, etching, and preparation in industries such as metal fabrication, automotive, and aerospace. The sharp and hard grains effectively remove rust, paint, scale, and other contaminants from surfaces without causing damage.

6. Superabrasives: In some applications, white fused alumina is used as a superabrasive material, either alone or as a component in bonded or coated abrasive tools. It can be used for precision grinding of hard and brittle materials like high-speed steels, tool steels, and ceramics, where high material removal rates and superior surface finishes are required.

7. Ceramics and Tiles: White fused alumina powder is used as an additive in the production of ceramics and tiles. It improves the strength, hardness, and thermal shock resistance of the final products.
