Alumina powder for polishing is an abrasive widely used in precision polishing. It has the characteristics of high hardness, good chemical stability and strong wear resistance. It is suitable for polishing of various materials such as metal, glass, ceramics, semiconductors, etc.
Superior properties of alumina powder for polishing
The alumina powder for polishing produced by Xiangrun has the following characteristics：
High hardness: Mohs hardness reaches 9, second only to diamond and silicon carbide, suitable for polishing hard materials.
Thermal stability: Melting point 2050℃, still stable at high temperature, suitable for high-speed polishing.
Controllable particle size: from micron level to nano level , to meet different precision requirements.
Inertness: Acid and alkali resistant (except strong acid and alkali), not easy to react with the polished material.
