Product Description:
Brown Fused Alumina Production and Properties
Brown Fused Alumina is a material that is produced by fusing bauxite in an electric arc furnace to create brownish colored granules with a high degree of hardness and toughness. The process takes place at high temperatures, and the product is manufactured in a tilting electric arc furnace. Due to its properties, the material has high resistance to high temperatures, strong erosion, and high machinery strength. Additionally, it has remarkable thermal stability. As a result, Brown Fused Alumina is a good choice of material for the production of shaped refractories.
Brown Aluminum Oxide: Manufacture and Applications
Brown Aluminum Oxide is produced by fusing premium raw materials and 3500 KVA furnace. The manufactured material is perfect for general abrasive applications that require bonded abrasive tools, polishing, and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide. However, it is a popular choice for grinding ferrous materials and finishing tough and hard materials due to its superior performance. Additionally, brown aluminum oxide can also be used as high-class refractor materials. The material is offered in macro and micro powder form, with both F and P grades available.
Features:
When it comes to sandblasting surface treatment, brown corundum is the go-to abrasive material for less dust during the process. Its high density allows for minimal dust produced during sandblasting, which is important for the health and safety of operators. Additionally, it improves operator visibility. Other abrasives like slag and quartz sand are relatively brittle and produce small particles during sandblasting, leading to potential environmental pollution.
Brown corundum is also efficient in sandblasting due to its ability, under certain pressure, to quickly impact the surface of the object with numerous sharp edges. This results in twice the cleaning rate of other conventional abrasives. The unique particle size of brown corundum also reduces the loss of abrasive during the process.

Applications:
The following are some of the popular abrasives commonly used in various industries.
Resin Abrasives
Resin abrasives are abrasive particles attached to a resin bond. The resin bond holds the abrasive particles together and provides a medium for cutting the surface of the workpiece. These abrasives are available in different colors, and they have good hardness, toughness, cross-sectional area, and edge retention. They are usually used in processes that require dry grinding.
Coating Abrasives
Coating abrasives are abrasive materials used as raw materials for the manufacturing of sandpaper and gauze. These abrasives come in different sizes and types and are applied to different surfaces to achieve the desired finish. They are commonly used in industrial applications where heavy-duty grinding is required.
Functional Fillers
Functional fillers are materials that improve the properties of a matrix material when used together. They are used in the production of automobile brakes, highway pavements, airstrips, parking lots, industrial floors, sports venues and other applications. These fillers can be made of different materials, including metals, plastics, and ceramics.
Filter Media
Filter media is a type of material used to purify drinking water or wastewater. It is commonly used in non-ferrous metal beneficiation, oil drilling mud weighting agents, and other industrial applications. The filter media can be made from different materials, including sand, gravel, and activated carbon.
