The main characteristics of the alumina ceramic cover
1. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
2. They offer different grade dimensional accuracy per sintered only, precision machining 
3. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics
4. High heat resistance: Alumina ceramic parts offer excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.
5. Good wear resistance: it is an ideal  choice  to wear parts in high abrasive industry
6. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
7. High corrosion resistance: It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
8. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parameters

The description of alumina ceramic cover
Alumina  (Aluminum oxide)  offers excellent electrical insulation, high-temperature resistance together with high hardness and good wear resistance, so alumina ceramic parts are commonly used as a kind of insulating, heat resistance and anti-chemical engineering and structural ceramic components, including ceramic electrical insulator, high voltage ceramic holder, ceramic parts in a high-temperature furnace, ceramic seal disc in pump and so on.  
Our factory produces a selection of purity of alumina from 40% to 99.8%,  all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. In order to achieve some special application for fitting, reducing the friction, increasing the insulation, we provide a serial of secondary processes after sintering, covering CNC machining, polishing, glazing, and metalizing.
We manufacture a wide range of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic disc, ceramic rod, ceramic arms, ceramic wire guides. Whatever, its a prototyping case, or high volume demand, we believe we are able to provide you a desirable solution.

The application of alumina ceramic parts
Alumina ceramic parts are widely used in the electronic, electrical, machinery, chemistry, ceramic seal, mineral, new energy, military, aerospace, almost all modern industries.
