Brown Corundum And White Corundum Difference

1, color is different: the color of white corundum and brown corundum is not the same. The color of white corundum is pure white, which can be transparent; And brown corundum color is mostly brown, and according to the size of the particle size of the color will also have a change in depth.

2, the content of alumina is different: the alumina content of white corundum is more than 99%, while the alumina content of brown corundum is 95-97%.

3, hardness is different: in terms of product hardness, the hardness of white corundum is much higher than that of brown corundum, which is related to the content of alumina said before, the higher the content of alumina, the greater the hardness and the better the quality.

4, for the user is different: since the scope of application of corundum and brown corundum is different, its users are also different. White corundum is suitable for a variety of high-end products, process or hardware and other products surface beautification treatment, can also be used to manufacture advanced refractory materials, for high-end users. Brown corundum is the most basic abrasive, because of its good grinding performance, wide range of application, cheap price, is widely used, so it is aimed at the mass user.

 

5, smelting method is different: white corundum is high quality aluminum oxide powder as raw material, by electric melting refining crystallization; Brown corundum is bauxite, coke (anthracite), iron filings as the main raw materials, in the arc furnace by high temperature smelting.

 

NYTWO brown corundum manufacturers suggest that the specific use requirements and needs should be considered when choosing. Such as:
1. Wear resistance: white corundum has higher hardness and better wear resistance than brown corundum. Therefore, in the need for high wear resistance, such as abrasives, grinding wheels and other manufacturing industries, white corundum is more often chosen.
2. Electrical conductivity: Brown corundum has certain electrical conductivity and can be used as an electrical material, which is more common in the field of electrolysis and electrochemistry. White corundum has poor electrical conductivity and is often used in insulating material applications.
3. Color: Brown corundum shows brownish-red, while white corundum shows white. According to personal preference or special decorative needs, you can choose the corresponding color of corundum material.
Therefore, the choice of brown corundum or white corundum should be determined according to the specific use scenario and requirements. If you need a material with high wear resistance, and the color requirements are not sensitive, white corundum is a good choice. If you need to have electrical conductivity or specific decorative effects, or the color requirements are more inclined to brownish-red, then brown corundum may be more suitable. For some special industrial needs, the selection can be made according to relevant standards and specifications.
