Product Description

Product Description:


Brown Fused Alumina is produced by melting bauxite in an electric arc furnace at high temperatures. The resulting product is of a brown color and features high hardness and extreme toughness. It is highly temperature resistant, resistant to erosion, mechanically strong, and thermally stable, making it a suitable raw material for the production of shaped refractories.


Brown Aluminum Oxide is produced through the fusion of premium raw materials in furnaces with 3500 KVA of power. Its various applications include abrasive work in grinding, polishing, and sandblasting, as well as refractory material. It's available in both F and P grades and can be found in either a macro or micro powder form.


While its hardness and abrasive capabilities are lower than those of diamond, boron carbide, and silicon carbide, aluminum oxide is still a widely used choice for grinding ferrous materials, and for finishing tough, hard materials.




Brown corundum was used as sandblasting surface treatment, due to its relatively high density, through which less dust is created in the process of sandblasting. This improves operator visibility and provides health and safety for operators.


Unlike traditional abrasive materials, brown corundum is a pure non-toxic mineral, which is free of substances like harmful free silicon, toxic heavy metals, or radioactive pollutants, all of which may lead to silicosis. Moreover, its low consumption and excellent recyclability also help reduce the cost of waste disposal.


Moreover, brown corundum can be widely used in multiple fields. Not only can it be repeated used if its cutting ability remains intact, but even after loss of the cutting ability, it can still be recycled and applied to constructions industry as cement additive.


Technical Parameters:


The chemical constitution of Al2O3 is ≥96.3%, SiO2 is ≤1.4%, Fe2O3 is ≤0.21%, TiO2 is ≤1.5%. And its physical properties are colour is brown, Mohs hardness as 9 and true density is 3.9 g/cm3; bulk density is 1.60~1.95g/cm3. Lastly, its Ig-Loss is ≤0.09%.




Wire sawing

  • Brown corundum is used in wire sawing operations for cutting complex shapes in a wide range of materials. This process is often used for precision parts in the aerospace, automotive, and medical industries.


Lining Materials

  • Brown corundum is a great choice for lining materials for furnaces and kilns due to its excellent resistance to high temperatures.


Grinding Paste

  • For polishing and tool manufacturing purposes, brown corundum is frequently used to make grinding pastes. These pastes are also used in optical lens grinding.


Ultrasonic grinding

  • When precision is needed, brown corundum is used in ultrasonic grinding, a non-contact machining process that is helpful in surface finishing and material removal.


Diamond grinding wheel binding agent

  • In order to produce a diamond grinding wheel with high precision, brown corundum is used as the necessary binding agent.


Metal surface treatment

  • Brown corundum is great for treating metal surfaces, such as cleaning, degreasing, and polishing.


Stone materials cutting

  • For cutting stone and concrete, brown corundum is used to produce cutting discs.
