Product Description

 

 

Alumina ceramic washer is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once fired and sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness.Additionally, it can be highly polished, making it useful for a wide range of applications.

 

Properties:

1. Good electrical insulation

2. Moderate thermal conductivity

3. High corrosion and wear resistance

4. Good gliding properties

5. High mechanical strength

6. High compressive strength

7. High hardness

 

DO YOU KNOW WHAT ALUMINA CERAMIC ARE?

 

Alumina ceramic is a kind of alumina as the main ceramic material,used in thick film integrated circuits.Alumina have good conductivity,mechanical strength and high temperature resistance.It should be noted that ultrasonic washing is needed.Alumina ceramics have a veriety of uses to meet the needs of daily use and specical properties.95 alumina porcelain is mainly used as waer-resisting parts.
