Feature of alumina ceramics:

1) High temperature resistance: alumina ceramic sealing ring can show excellent stability in high temperature environment, can withstand high temperature and thermal cycle, and is not easy to deformation and rupture.
2) Corrosion resistance: Due to its good chemical stability and inert surface, alumina ceramic sealing rings can resist corrosion and oxidation, so that it can maintain stable performance in a variety of corrosive media.
3) High hardness: alumina ceramic sealing ring has high hardness, maintain stable shape and sealing performance under vibration and high pressure environment, and has good wear resistance.
4) Insulation: alumina ceramic sealing ring is an excellent insulating material, which can maintain good insulation performance under high pressure environment and effectively isolate the conduction of electric and thermal fields.
5) Low coefficient of thermal expansion: The thermal expansion coefficient of alumina ceramic sealing ring is low to adapt to the thermal expansion and contraction under high temperature conditions, reducing the stress and damage caused by temperature changes.

Advantages of alumina ceramics:

1.Dimensional and thermal stability, high performance characteristics, hydrolysis resistance, self-lubrication, extended service life, reduced downtime and cost, low moisture content, noise reduction

Application of alumina ceramic ring:
Alumina ceramic sealing rings are widely used, and the following is the introduction of its main application scenarios:
1) Aerospace field: In aerospace equipment, alumina ceramic sealing rings can be used for sealing and insulation in engines and gas turbines, which can withstand high temperature and high pressure environments to ensure the normal operation of equipment.
2) Chemical field: alumina ceramic sealing ring can be used in chemical equipment for the sealing of high-temperature reaction vessels and pipelines, effectively isolating the leakage of harmful gases and liquids, and ensuring process safety and environmental protection.
