Product Description

Product Description:

 

Brown Fused Alumina is produced in a very special way. It is made through a fusion process, wherein bauxite is fused in an electric arc furnace at very high temperatures. The resulting product is a brownish coloured material that is both hard and tough. It also has many desirable traits such as high temperature resistance, strong erosion resistance, high machinery strength and thermal stability.

 

Another, similar product is Brown Aluminum Oxide. It is made by fusing premium raw materials in a 3500 KVA furnace. It has many uses, ranging from general abrasive applications, sandblasting and polishing, to grinding ferrous materials and finishing tough and hard materials. It is even used in the production of refractory materials of the highest quality. It is available in both macro and micro powder form, marketed as either F or P grade.

 

Features:

 

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. It does not contain any harmful free silicon substances that lead to silicosis, toxic heavy metals or radioactive pollutants. Furthermore, it has low consumption and recyclability, which can drastically reduce the amount and cost of waste disposal after use.

 

Brown corundum is exceptionally suitable for a variety of fields. Normally, it can be reused for several times. If it has not lost its cutting ability after the first time, the number of cycles can be more. Even if it has lost its cutting ability, brown corundum can still be recycled and used as a cement additive in the construction industry.

 

Technical Parameters:

 

This substance has the following chemical constitution:

  • Al2O3: ≥96.3%
  • SiO2: ≤1.4%
  • Fe2O3: ≤0.21%
  • TiO2: ≤1.5%

 

The physical properties of this substance includes:

  • Colour: brown
  • Mohs hardness: 9
  • True density: 3.9 g/cm3
  • Bulk density: 1.60~1.95 g/cm3
  • Ig-Loss: ≤0.09%

 

Applications:

 

Brown Corundum has many uses, as it is a useful abrasive with many applications. Here are some of the common uses for Brown Corundum.

 

  1. Wire sawing: Brown Corundum is used as an abrasive for wire sawing operations. This sawing technique is used to cut complex shapes in a wide range of materials.

 

  1. Precision casting: Brown Corundum is used in precision casting. It is an excellent choice of material for the production of high accuracy components for the aerospace, automotive, and medical industries.

 

  1. Lining materials: Brown Corundum is an ideal choice for lining materials for furnaces and kilns due to its resistance to high temperature.

 

  1. Grinding paste: The abrasive properties of Brown Corundum are advantageous for producing grinding pastes. It is used in Optical Lens grinding, tool manufacturing, and polishing.

Fine-tech Brown Aluminum Oxide is an industrial alumina powder, produced by the melting of bauxite in an electric arc furnace. It is also known as brown fused alumina or brown fused aluminum oxide. It is tougher and more blocky than white aluminum oxide. It is recommended when more cutting action is desired.

 

Packing and Shipping:

 

Brown Aluminum Oxide is packaged and shipped in 25kg bags for transport by truck or rail. The bags are labeled with the product name, weight, and any other relevant information. The bags are packed in sturdy cardboard boxes with additional padding to prevent damage during transport.
