Precision Machining 2000mm Alumina Ceramic Parts Alumina Ceramic Ring
Precision Machining Alumina Ceramic Ring
Description:
We manufacture & supply advanced technical ceramic rings custom machined to your specific design. Ceramic rings are finding their way into more and more application due to their highly desirable mechanical, thermal, and electrical properties. Ceramic rings can be used in extreme environments unlike many other materials. Precision Ceramics has a wide assortment of ring sizes available; depending upon the material, we can machine ring with incredibly tight tolerances. Additionally, Precision Ceramics has standard size Alumina rings available in a variety of sizes and purities. Other materials may be available in custom dimensions and specifications.

Advantages:
1.High strength and hardness.
2. Good wear resistance.
3. Insulation, corrosion resistance.
4. High lubrication and low resistance.
Application:
1.Alumina plates are hard enough to become armor for personnel or vehicles.
2.The corrosion resistivity of alumina plates makes them a great material for the chemical industry.
3.Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
