Product Description

Product Description:

Al2O3 Colour Of Aluminium Oxide With High-Performance And Density 3.95 G/Cm3

Brown corundum is a highly versatile material that is commonly made from bauxite and coke, produced in an arc furnace at high temperatures. Its properties of short grinding time, high efficiency, and low cost make it highly desirable for abrasive blasting. It has a moderate hardness, high toughness, and good self-sharpening ability, leading to low sand consumption and the ability for recycling and reuse. Its stable chemical composition also makes it resistant to wear, acid, and alkali. The unique conchoidal structure of brown corundum allows for sharp edges and corners, enabling it to continuously form new edges and corners while grinding, giving it a superior ability compared to other abrasives.



Brown corundum is a pure and non-toxic mineral, unlike conventional abrasive materials. It does not contain harmful free silicon, toxic heavy metals, or radioactive pollutants. Additionally, its low consumption and recyclability greatly reduce waste disposal costs after use.


Brown corundum is highly versatile and can be reused multiple times in various fields. If it retains its cutting ability after the first use, it can be recycled even more. When it loses its cutting ability, it can still be recycled and used in the construction industry as a cement additive.

Grinding is another common method used in industries such as picture tube production, optical glass manufacturing, and monocrystalline silicon production. This process involves the use of an abrasive material, such as a grinding wheel, to remove small layers of material from a surface, resulting in a smoother and more precise finish.


Resin abrasives are a type of abrasive material with a range of properties, including suitable color, hardness, toughness, and edge retention. They are commonly used in industries such as metalworking and woodworking to produce high-quality finishes on various materials.
