High purity alumina ceramic seals

High purity alumina ceramic seals refer to sealing components with alumina content of 99.5% or even 99.9% or more, which have extremely high physical and chemical properties and are suitable for extreme working conditions.

Main features:
High hardness and wear resistance: The Mohs hardness can reach level 9, with extremely strong wear resistance, suitable for high friction environments.
Corrosion resistance: It has strong corrosion resistance to most acids, bases, salts, and organic solvents.
High temperature resistance: Long term use temperature can reach 1600 ℃, and short-term use temperature is even higher, suitable for high temperature conditions.
High strength and toughness: High fracture strength, able to withstand significant pressure and impact.
Electrical insulation: Excellent performance in the fields of electronics and electrical engineering.
Biocompatibility: Suitable for scenarios such as medical devices that require high material safety.
High purity: The alumina content is extremely high, with fewer impurities and more stable performance.
