95 Fine grinding alumina ceramic ring

Alumina ceramic rings have a variety of excellent physical and chemical properties.

1. High hardness
   The alumina ceramic ring has an extremely high hardness, which can reach Mohs hardness level 9, the same as corundum, far exceeding stainless steel and wear-resistant steel, which makes it excellent in terms of wear resistance and resistance to wear and scratches.
2. Wear resistance
   The wear resistance of alumina ceramic rings is excellent, and the wear resistance can rival that of superhard alloys, which is more than 15 times that of magnesium oxide ceramics, making it suitable for high wear environments.
3. High temperature resistance
   Alumina ceramic rings have excellent high temperature resistance and can withstand temperatures above 1600 ° C, making them suitable for high-temperature working environments.
4. Corrosion resistance
   Alumina ceramic rings have good chemical resistance, can resist the erosion of a variety of chemical substances, and are suitable for corrosive environments.
5. Insulation properties
   Alumina ceramic rings have excellent electrical insulation properties, low dielectric loss and high volume resistivity, making them suitable for high voltage insulation components.
6. Mechanical strength
   Alumina ceramic rings have high mechanical strength, including tensile strength, flexural strength and compressive strength, and can withstand large mechanical pressures.
7. Thermal stability
   The alumina ceramic ring has small thermal expansion coefficient, good thermal conductivity, good thermal stability, and is suitable for environments with large temperature changes.
8. Self-lubricating
   Alumina ceramic rings have the characteristics of good self-lubrication and not easy to scale, making them suitable for mechanical parts that require lubrication.
9. Processing characteristics
   Due to the high hardness and brittleness of alumina ceramic materials, the processing is difficult, and hard materials such as silicon carbide, boron carbide, and diamond diamonds are usually required for grinding and polishing. Laser processing and ultrasonic processing methods can also be used for finishing.
10. Widely used
    Alumina ceramic rings are widely used in machinery manufacturing, aerospace, precision instrumentation, petrochemical, new light sources, textile machinery, electrical appliances, refrigeration equipment, electric heating meters, instruments, chemicals, communications and other industries.

These characteristics make alumina ceramic rings widely used in a wide range of fields, meeting the needs of a variety of high-temperature, wear-resistant, corrosion-resistant, and high-strength environments.
