Design Features

Alumina ceramic wheels, also known as porous ceramic sealing ring flanges, showcase the excellent physical and chemical properties of alumina (Al2O3):

High Hardness and Excellent Wear Resistance

Alumina's Vickers hardness reaches 15.7 GPa, ensuring durability and long service life in high-wear environments.

Good Thermal Stability

A high thermal conductivity of 27.5 W/(m.K), combined with a maximum operating temperature of 1650°C, allows it to maintain structural and functional 

stability in high-temperature applications.

Excellent Electrical Insulation

With a breakdown strength of >10 KV/mm and low dielectric loss, it is suitable for use as an insulating material in electrical applications.

Precise Drilling and Shape Design

Multiple holes included in the design not only serve for fixing but also act as channels for fluid or gas, enhancing its functionality in sealing and fluid 

control systems.

Smooth Surface Finish

A uniform white appearance and smooth surface help reduce friction, providing consistent sealing performance and minimizing leakage.

Application areas

Alumina ceramic wheels have a wide range of applications in multiple industrial sectors:

Chemical Processing

As sealing and isolation components for piping systems in high-temperature or corrosive environments, their chemical stability and heat resistance ensure 

long-term reliability.

Precision Machinery and Electronic Equipment

Used in equipment requiring precise control of fluid flow and maintenance of environmental stability, such as in semiconductor manufacturing and 

specialized machinery.

Medical Devices

Due to their biocompatibility and chemical resistance, they are suitable for various components in medical devices, especially in environments requiring strict 

sterility.

Automotive and Aerospace Industries

Used in engine components and aerospace parts to provide sealing and structural support in environments subjected to high temperatures and chemical 

corrosion.

Alumina ceramic wheels play a crucial role in modern industrial systems due to their superior wear resistance, high-temperature stability, and electrical 

insulation. These properties make them ideal for high-temperature, high-corrosion, and high-wear conditions, particularly in chemical processing, precision 

machinery, and medical devices. Precise drilling and shape optimization in the design not only enhance their structural integrity but also improve performance 

efficiency during assembly and use. The versatility and high performance of alumina ceramic wheels ensure long-term reliable operation in challenging 

application environments, meeting the industry's ongoing demand for high-performance materials.
