Design Features

Porous alumina ceramic gaskets (also known as laser-cut ceramic rings) are key components for industrial equipment and precision 

machinery designs that require high precision and durability.

Precision-machined Holes and Unique Shapes

These gaskets feature multiple precision-machined holes and specific shape designs for precise positioning and fixation in equipment.

High Hardness and High Strength

The high hardness (Vickers hardness up to 15.7 GPa) and high strength (compressive strength up to 2000 MPa) of alumina ceramics ensure 

that they maintain their shape and function under high pressure and high friction environments, enhancing long-term stability and durability.

Excellent Corrosion Resistance

Outstanding chemical stability enables them to resist corrosion from a variety of chemicals, especially at high temperatures, preventing 

material corrosion and degradation.

Electrical Insulation and High-Temperature Resistance

Good electrical insulation properties and high-temperature stability allow these gaskets to be used safely in high-voltage and 

high-temperature industrial applications.

Application areas

Industrial Equipment and Machinery

Used in industrial pumps, valves, or other fluid power equipment requiring precise fluid control and fixation.

Electronics and Electrical Industry

Used as electrical insulation components in electrical equipment to protect circuits from high temperatures and high voltages.

Laser Cutting and Processing

Used in laser cutting machinery for precise positioning and protection of the cut surface from mechanical damage.

High-Temperature Environment Applications

Suitable for chemical and metal processing industries requiring high temperature resistance and chemical stability.

Porous alumina ceramic gaskets offer reliable performance in a variety of industrial environments due to their superior mechanical strength, 

wear resistance, corrosion resistance, excellent electrical insulation, and high-temperature resistance. They are particularly suitable for 

high-end applications requiring extreme durability and precision. These properties make alumina ceramic gaskets an indispensable 

component in modern industrial technology applications.
