The main advantages of alumina balls are:
1. It is 50% lighter than the steel ball, reducing the centrifugal force, rolling and wear of the channel during high-speed and accelerated operation of the bearing;
2. Small friction coefficient and good rotational flexibility;
3. High temperature resistance, the service temperature can reach 1750 ℃;
4. Never rust, can work without oil lubrication;
5. More resistant to chemical corrosion than steel;
6. No metal pollution;
7. Non magnetic;
8. Electrical insulation.

Purpose:
Alumina ceramic balls are resistant to wear, heat, oxidation, water, salt solution and other chemical substances and acids. Another feature is the ability to maintain dimensional stability up to 1100 ℃. Alumina ceramic balls are not suitable for hydrochloric acid, hydrofluoric acid and strong alkali solutions. It is mainly used for pumps, valves and flow meters.
Product features: alumina content is 99.5%, and alumina balls with 99.8% content can be provided according to customer requirements.
Product specification: 1.588mm ~ 100mm.
Available supply levels:
G16~G60。
remarks:
1) There is a large inventory of alumina balls.
2) It can meet the requirements of various non-standard sizes.
3) The toughness of alumina ball is relatively low.
4) Compared with silicon nitride ball, alumina ball is more suitable for low cost applications.
