9.0 Mohs White Aluminum Oxide Grain Size Sand Grinding F30 For Industry Grinding

9.0 Mohs Hardness White Aluminum Oxide F30 Industry Grinding

1. Introduction

White corundum is made from industrial alumina powder, which is melted in arc furnace at a high temperature of more than 2000 degrees and then cooled. After grinding and shaping, magnetic separation of iron, particle size screening into different products. With the close texture, high hardness, angular shape, it is suitable for the manufacture of ceramics, resin consolidation abrasive tools and grinding, polishing, sandblasting, precision casting (investment casting special corundum), and it can also be used for the manufacture of high-grade refractory materials.

2. Attribute

1.Chemical composition: Al2O3

2.Density: 3.95g/cm³

3.Hardness: 9.0 Mohs hardness

4.Crystal structure: Tripartite crystal system

5.Surface roughness: High hardness makes white corundum can be used to polish the surface of glass, metal and other materials, and the surface roughness can reach 0.02µm

3. Advantages

4. Applications

1. White corundum grinding wheel is the main finishing tool in metal processing. Because of its high hardness and good stability, it can meet the requirements of different processing occasions.

2. It can be used as solid coated abrasive tools, wetting or dry sand blast. It can be used as super fine grinding, polishing and making high-grade refractory materials for crystal, electronic industry.

China Changsha Fine-Tech Ceramic Co., Ltd. was established in 2009 as an associated company of Furthertrading GmbH in China, which has been working in the new material industry for more than 30 years and is committed to providing quality material supply and solutions to customers worldwide. With the aim of "solving problems for our customers and creating value for them", we have actively invested in research and development, cooperated with universities and research institutes at home and abroad, and successfully introduced and produced various new technologies and products.

The company has introduced advanced technology from Europe and independently produced zirconium silicate, zirconium oxide and alumina grinding and sandblasting media with strict quality management system, leading the technical level of the domestic industry, and has been sold to all over the world for a long time, simultaneously promoting the progress of metal surface treatment technology in domestic consumer electronics, aerospace and precision casting industries.

In 2012, the company started a deep cooperation with NABALTEC in Germany and became the company's agent in China, committed to bringing high-end process alumina powder into the Chinese market, with the advantage of German technology, to help customers provide total solutions, in metal and non-metal material polishing, special precision ceramics, thermal conductivity, refractory materials and other industries are widely recognized and applied by domestic customers.
