Product Description

Product Description:

Brown Fused Alumina is produced by the fusion of bauxite in an electric arc furnace at high temperatures. The brownish colored product has both high hardness and extreme toughness, along with its high temperature resistance, strong resistance to erosions, and high machinery strength. Furthermore, it has thermal stability, making it a great raw material for producing shaped refractories.


Brown Aluminum Oxide is created from premium materials and a 3500 KVA furnace. It is mainly used for general abrasive applications such as those found in bonded abrasive tools, polishing tools, and sandblasting tools. While its hardness and abrasive capacity are lower than those of diamond, boron carbide, and silicon carbide, it is still frequently used for grinding ferrous materials and finishing hard and tough items. Moreover, it is an excellent material for high-grade refractories that is offered in both macro and micro powder form, under the F and P grades.



Brown corundum was used as sandblasting surface treatment, because of its relatively high density, so that is less dust in the process of sandblasting. This ensures operator health and safety, at the same time it can improve operator visibility.Different from conventional abrasive materials, brown corundum is a pure non-toxic mineral, which does not contain harmful free silicon substances that lead to silicosis, toxic heavy metals or radioactive pollutants. In addition, the low consumption and recyclability of products can greatly reduce the amount and cost of waste disposal after the product is used.


Brown corundum is very suitable for many fields. Normally, it can be reused several times. If it has not lost its cutting ability after the first time, the number of cycles can be more. Without cutting ability, brown corundum can also be recycled and applied to the construction industry as cement additive.

Brown corundum is used for many applications. In wire sawing operations, it is used as an abrasive to cut complex shapes in a wide range of materials. It is also used in precision casting, producing high accuracy components for the aerospace, automotive, and medical industries.


Brown corundum also has excellent resistance to high temperatures, which makes it ideal for lining materials for furnaces and kilns. It is used in grinding pastes and diamond grinding wheels, which are typically used for optical lens grinding, tool manufacturing, and polishing. Additionally, it is used in ultrasonic grinding, a non-contact machining process commonly used in surface finishing and material removal operations.


Brown corundum is also used in metal surface treatment, removing contaminants, cleaning, degreasing, and polishing. Finally, it is used in the production of cutting discs used for cutting stone and concrete.
