Product Description:
Brown Corundum: A Versatile and Essential Material in Abrasive Blasting Process
Brown corundum is a highly versatile and widely used material that is derived from bauxite and coke (anthracite). It is produced through the high-temperature smelting process in an arc furnace. With its excellent grinding properties, such as short grinding time, high efficiency, and low cost, brown corundum is favored by many industries.
The product not only boasts moderate hardness and high toughness but also has the ability to self-sharpen, resulting in low sand consumption, easy recycle and reuse, and a superior grinding finish. Its stable chemical composition makes it resistant to wear, acids, and alkalis. The unique conchoidal structure of brown corundum, with sharp edges and corners, enables the formation of new edges and corners during continuous grinding, giving it an edge over other abrasive materials.
Features:
Low Depletion
The exceptional particle size of brown corundum guarantees a higher rate of impact on the surface of the target, resulting in significantly reduced abrasion.
High-quality Surface Treatment
During the sandblasting process, brown corundum has the ability to penetrate deeply into surface imperfections and reach the bare metal underneath, effectively removing all rust, soluble salts, and other pollutants. This results in a clean, embedment-free metal surface of exceptional quality. In comparison, materials such as copper slag and nickel slag often leave coarse, sharp fragments on the steel surface after sandblasting, which can compromise initial coating and overall coating effectiveness.
The Environment
Distinguishing itself from traditional abrasive materials, brown corundum is a pure, non-toxic mineral that does not contain any harmful free silicon, toxic heavy metals, or radioactive pollutants that can lead to conditions like silicosis. Additionally, the low consumption and recyclability of brown corundum can significantly reduce the amount and cost of waste disposal once the product is utilized.

Applications:
Sandblasting
Sandblasting is a common method used for surface treatment in various industries, such as environmental protection, aluminum profile manufacturing, copper profile production, and precision mold making. It involves propelling fine particles at high speed to clean, roughen, or smooth a surface. Sandblasting is widely used in industries such as:
- Environmental protection materials
- Aluminum profile production
- Copper profile glass manufacturing
- Washed denim for jeans
- Precision mold making
Grinding
Grinding is another common method used for surface treatment, especially for delicate materials. It involves using a tool with a rough surface to remove small particles from a surface, resulting in a smoother, more polished finish. Grinding is commonly used in industries such as:
- Picture tube manufacturing
- Optical glass production
- Monocrystalline silicon processing
- Lens manufacturing
- Watch glass production
- Crystal glass shaping
- Jade carving
Resin Abrasives
Resin abrasives are a type of abrasive material known for their good hardness, toughness, and suitable particle cross-section type. They are commonly used for grinding and polishing in various industries. Resin abrasives are often used in manufacturing processes that require precise finishing, such as:
- Automobile manufacturing
- Electronic device production
- Art and craft production
