Alumina ceramic wheels Alias: Porous ceramic sealing rings / flange rings
Description：
Wheels made of alumina (Al2O3) ceramic, also known as porous ceramic sealing rings / flange rings. Designed with multiple holes, these can be used for fixation or as part of a fluid, gas channel, increasing their functionality in sealing and fluid control systems. For example, these wheels can be installed at the connection points of piping systems to serve as sealing and isolating components in high-temperature or corrosive environments.
Features:
Alumina ceramic wheels, alias porous ceramic sealing rings / flange rings, demonstrate the outstanding physical and chemical properties of alumina (Al2O3):
— High hardness and excellent wear resistance
Alumina has a Vickers hardness of 15.7 GPA, ensuring its durability and long life in high-wear environments.
— Good thermal stability
The thermal conductivity of up to 27.5 W/(m ▪ K), combined with a maximum operating temperature of 1650℃, allows it to maintain structural and functional stability in high-temperature applications
— Excellent electrical insulation
It has a breakdown strength of up to >10 KV/mm and low dielectric loss, making it suitable for use as an insulating material in electrical applications.
— Precise Punching and Shape Design
Designed with multiple holes not only for fixation but also as channels for fluids or gases, enhancing their functionality in sealing and fluid control systems.
— Smooth finish treatment
he uniform white appearance and smooth surface help reduce friction, providing consistent sealing performance and reducing leakage.
Applications:
Alumina ceramic wheels have a wide range of applications in several industrial sectors:
1. Chemical treatment
