High Quality Brown Fused Alumina-Manufacturers’ First Choice

Most abrasives manufacturers said brown fused alumina products are reliable, which has not only stable performance, but good quality, and is easy to use. It is not only the first choice of the abrasives industry, but also is the first choice of refractory materials.

Firstly, brown fused alumina has high temperature resistance, corrosion resistance, high strength and other perfect performance, so it is often used for smelting rare metals, special alloy, ceramics, furnace lining (wall and pipe); Physical and chemical vessels, spark plugs, heat-resistant oxidation coating.

Secondly, brown fused alumina has high hardness, good wear resistance, high strength and other characteristics. In the chemical industry system, it is used for all sorts of reaction vessels and pipes, chemical pump parts, mechanical parts, all kinds of molds, such as wire drawing die, pencil lead mold mouth; it also can be used as abrasive tools, moulds, bulletproof materials, human body joint, etc.

Thirdly, it can be used as corundum thermal insulation material with high temperature resistant and heat preservation. For example, corundum light brick, corundum hollow ball and fibre products are widely used the furnace wall and furnace top of various high temperature furnaces. Brown fused alumina size sand is the artificial corundum block, which is made by using the equipments such as roller, ball mill, barmac and the granularity is F8-F325. It is mainly used for polishing, grinding, industry grinding, etc., and can also process by means of water washing, acid pickling treatment according to customer requirements, meeting the different needs of customers.

Therefore, brown fused alumina is not only the first choice of the abrasives industry, but also is the first choice of refractory materials industry, which is mainly used in ceramic abrasive products, high-grade abrasive products, organic abrasive products, abrasive belt, coated abrasive products, etc. According to the residual carbon content, it is divided into: calcined brown fused alumina C ≤0.05%, low carbon brown fused alumina C ≤0.10%, and common brown fused alumina C ≤0.15%.
