Product Description

Product Description:

Brown Corundum is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.


Brown Fused Alumina is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish coloured product shows high hardness as well as extreme toughness. It is produced by fusion of bauxite in a tilting electric arc furnace at high temperatures. The product shows high temperature resistance, strong erosion resistance, high machinery strength as well as thermal stability. It is a good raw material for manufacturing of shaped refractories.


Brown Aluminum Oxide  are fused with premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials.



Brown corundum was used as an surface treatment method due to its relatively high density which results in less dust being produced during the process of sandblasting. This improves the health and safety of operators, and also increases visibility. However, sandblasting created with slag produces more dust. This occurs due to the glass-phase structure formed when cold water or even seawater is used for high temperature cooling. Slag is brittle, which causes it to be more easily able to be smashed into small particles in comparison to brown corundum. Additionally, the slag’s density is relatively small, leading to small particles being suspended in the air and creating environmental pollution.


The higher efficiency of brown corundum is largely due to it’s fragments having sharp edges when under a certain pressure. This allows for a larger amount of particles to hit the surface of the object at a faster rate. Additionally, due to the smaller size of the particles, it is easier to accelerate them which produces a higher impact force, resulting in an increased cleaning rate than other conventional abrasives. This also creates a lesser need for the product being used as less is lost due to the higher efficiency.

Brown Aluminum Oxide, also known as Brown Fused Alumina, is an abrasive made of fused and crystallized alumina with a hardness of 9 on the Mohs scale. It is characterized by its brown colour and its excellent thermal properties, making it an ideal material for various industrial applications. Fine-tech's Brown Aluminum Oxide, with model number P240, is sourced from Changsha China and is ISO9001 certified. It has a melting point of 2050°C and is insoluble in water, with a non-toxic composition. It is available in 500KG minimum order quantity and is offered in 25kg/barrel, 25kg/bag, and 1t/pallet packaging. Its price is negotiable and delivery can be expected within 5-15 work days. Payment terms are L/C or T/T. The product is available in a supply of 2000t per year and should be stored in a dry, cool, and well-ventilated environment.


Brown Aluminum Oxide is widely used in industries such as abrasive, grinding, lapping, polishing, refractory, sandblasting, and others. It is used as an abrasive in applications such as grinding wheels, sandpaper, blasting media, metal preparation, and lapping compounds. It is also used as a raw material in the production of refractory products and as a filler material in coatings and adhesives. As a result of its excellent thermal properties, it is also used in the production of ceramic tiles, fireproof materials, and firebricks.


Fine-tech's Brown Aluminum Oxide is an ideal material for numerous industrial applications due to its excellent thermal properties, abrasive properties, and non-toxic composition. It is available in a variety of packaging options and is offered at a negotiable price with quick delivery.
