High Precision Wear Resistant Polished 99% Alumina Ceramic Piston
Product Characteristics
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 for ceramic wear parts in the 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
Pruduct Application
Ceramic plungers are commonly used in the machinery manufacturing and chemical industries for sealing and fluid control.
In the machinery manufacturing industry, ceramic plungers are widely used in precision machinery such as high-pressure injection pumps, plunger pumps, automobile engines and aircraft engines to improve mechanical sealing and wear resistance.
In the chemical industry, ceramic plungers are often used in chemical reactors and piping systems for high temperature and corrosion resistant media.
