Product Description:

Brown Aluminum Oxide Regular And Sharp-edged Grain Shape

Brown corundum is created out of high-quality bauxite, anthracite, and iron filings, which undergo arc melting at temperatures of 2000°C or higher. By utilizing a self-grinding machine, it is crushed and plasticized, so the iron filing can be removed through magnetic selection. Afterwards, the corundum is sieved into various sizes and boasted for its dense and hard texture. The pellets are spherical, ideal for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, and precision casting. Asides from that, brown corundum is also well-suited for manufacturing high-grade refractories.

Moreover, brown corundum abrasive is widely acclaimed for its characteristics such as high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. It enjoys a great reputation among fire-proof production companies, not to mention it excels in explosion resistance, chalking ineffectiveness, and crack prevention. Especially considering its reasonable cost-effectiveness compared to traditional corundum abrasives, brown corundum is recognized as the best aggregate and filler material for fused alumina refractories.

Features:

Brown corundum has unique properties that are beneficial for sandblasting surface treatment. It is less dusty, thus ensuring operator safety and improved visibility. Brown corundum has high efficiency that can quickly impact the surface of the object, resulting in a fast spray grinding method. Not only that, its particle size ensures that more effective particles can hit the surface of the object, and it can greatly reduce the loss of abrasive. In addition, Brown corundum can go deep into the holes and pits on the surface of the object, remove all rust, water-soluble salts and other pollutants, thus achieving high quality surface treatment. Aside from its performance, the use of brown corundum has environmental benefits. It is a pure non-toxic mineral that does not contain harmful free silicon substances, toxic heavy metals or radioactive pollutants. Finally, brown corundum can be reused several times, and the number of cycles can even be more if it has not lost its cutting ability after the first time.

Applications:

Brown corundum is widely used in many different industrial applications. It is commonly used in wire sawing operations as an abrasive to cut complex shapes into a wide range of materials. Precision casting also utilises brown corundum to create high accuracy components for the aerospace, automotive and medical industries. Additionally, it is utilised as a lining material to protect furnaces and kilns, due to its excellent heat resistant qualities.

Brown corundum is employed for grinding pastes, including optical lens grinding, tool manufacturing and polishing. It is used in ultrasonic grinding too, a non-contact machining process used for surface finishing and material removal operations. Additionally, brown corundum is applied as a binding agent in diamond grinding wheels, usually used for high-precision grinding. This material is also employed in metal surface treatment, such as cleaning, degreasing and polishing.

Some other uses of brown corundum include stone materials cutting, dry sanding, coated abrasives materials, and non-skid flooring. It is typically used in the production of cutting discs to cut stone and concrete. Dry sanding utilises brown corundum to remove stains and clean surfaces on metals and other materials. As for coated abrasives, it is used to create sandpaper and abrasive belts. Lastly, it is an excellent non-skid flooring material, providing traction and preventing slips and falls in high traffic areas.
