The main characteristics of the technical ceramic parts
1. They offer different grade dimensional accuracy per sintered only, precision machining
2. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics
3.. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
3. 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.
4. Good wear resistance: it is an ideal  choice  to wear parts in high abrasive industry
5. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
6. 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.
7. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parameters

The description of alumina ceramic parts
Aluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.
Our factory produces a selection of purity of alumina from 75% 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.

Application and After-Sales Service:

We offer full range of ceramic washer, spacer, seal ring and other parts for industry applications like bushing, pump seal ring, shaft ring, etc.

Our alumina ceramic rings/loops are exported to USA, Canada, Europe, and South America and Southeast Asia.

After-sales service:

Accept any repair of the product, help to improve technology for customer. And also provide long-term technical help and support for you.
