Alumina ceramic sealing ring Industrial machinery ceramic ring high hardness insulation abrasion resistant

product name:Alumina insulating ceramics

Characteristics of alumina ceramic ring:

Alumina industrial ceramics have high hardness, high strength, and insulation, wear resistance, corrosion resistance, and are used in machinery manufacturing, aerospace, petrochemical and other fields. Because of its superior performance, alumina industrial ceramics have been more and more widely used in modern society to meet the needs of daily use and special properties.

1 High temperature resistance : It has high thermal stability and high temperature resistance, and can work stably in high temperature environment for a long time without deformation, softening or thermal expansion.
2 Corrosion resistance : The surface of the ceramic material is flat and has good corrosion resistance. It can work stably in strong corrosive media such as acid, alkali and salt for a long time.
3 Wear resistance : It has high wear resistance and impact resistance, and can effectively withstand the erosion of the medium and particle wear, thus extending the service life of the ceramic ring.
4 Stability : It has good stability, can maintain stable performance in long-term use, and is not susceptible to external interference and influence, thereby improving the reliability and stability of the ceramic ring.
