ホワイトコランダム and 茶色のコランダム with strong grinding power differ in many aspects. Here are the main differences between them:

Raw materials and ingredients:

ホワイトコランダム: Made from industrial alumina powder, it has a high alumina content, so other impurities such as titanium oxide and ferric oxide are relatively low.

茶色のコランダム: Made from bauxite, 無煙炭, and iron filings, its alumina content is slightly lower than that of white corundum.

Physical properties:

硬度: The Mohs hardness of white corundum is about 9, and the hardness of brown corundum is slightly lower than that of white corundum.

Toughness: Brown corundum has good toughness compared to white corundum, which makes it more advantageous in specific application scenarios.

Crystal structure: The crystal structure of brown corundum is a trigonal system, and the crystal surface formed is relatively flat, which can produce a more directional cutting effect. Although white corundum also has a high cutting ability, its crystal structure characteristics are different from those of brown corundum.

Grinding force and application:

Under the same grinding conditions, white corundum exhibits grinding force due to its high hardness and thermal stability. This makes white corundum advantageous in grinding hard materials such as hardened steel, high carbon steel and other materials.

Brown corundum can also produce cutting effects in certain application scenarios due to its high toughness and specific crystal structure. For example, in the processing of materials such as glass and ceramics, brown corundum is a suitable choice.

In general, white corundum and brown corundum each have their own characteristics and advantages, suitable for different grinding scenarios and materials. When choosing, decisions need to be made based on specific application requirements and workpiece materials. 同時に, when using these abrasives, relevant operating procedures should be followed.
