Purity: 99.5+%, Size: 1-10 μm

Aluminum Oxide (

Al_{2}O_{3}

) Micron Powder is a high-purity, alpha-phase crystalline material characterized by its exceptional hardness and superior friability. This 1-10 μm micro-powder features a sharp, blocky morphology that facilitates a self-sharpening mechanism; the crystals fracture under mechanical stress to continuously expose fresh, sharp cutting edges to the workpiece. Its high thermal stability and "cool cutting" capability make it an ideal abrasive for heat-sensitive alloys and precision grinding of high-speed steels, ensuring minimal thermal distortion. Chemically inert and highly resistant to wear, this micronized powder provides excellent dimensional stability and consistent performance in demanding applications ranging from vitrified bonded tools to specialized surface finishing.

Applications

Precision Grinding and Abrasives: Used in the precision grinding of high-speed steels and heat-sensitive alloys. The material’s high friability ensures a "cool cutting" process by constantly exposing fresh sharp edges, preventing thermal damage to the workpiece.
Bonded Abrasive Tools: Widely utilized in the manufacturing of vitrified grinding wheels, segments, and internal grinding wheels. Its low soda and silica content allows for the production of the whitest and most stable vitrified wheels possible.
Surface Finishing and Polishing: It is ideal for fine lapping and polishing applications where dimensional accuracy is critical.
Refractory and Industrial Materials: Functions as a synthetic raw material for high-performance refractory and industrial applications. Its alpha alumina phase and high specific gravity provide excellent structural integrity at elevated temperatures.
