Alumina Thermal Conductive Ceramic Parts


Alumina ceramic products have many excellent properties, such as high wear resistance, high mechanical strength and chemical resistance. Therefore, it is widely used in various fields. The most common of them are in the fields of machinery manufacturing, chemical industry and electronic technology. For example, cylinder liners, bearings and mechanical seals for automobile engines can be manufactured using alumina ceramics because of their high wear resistance and high strength. In addition, alumina ceramic products can also be used in chemical containers, protective equipment and electronic instruments, because they have very good chemical resistance and insulation properties.


Our alumina ceramic products mainly include: 

① wear-resistant and corrosion-resistant alumina balls and liners;

② alumina wear-resistant ceramic tanks; 

③ wear-resistant alumina liners, liners;

④ wear-resistant and corrosion-resistant alumina ball valves;  

⑤ alumina cylinder liners for the oil field;

⑥ all kinds of alumina ceramic material products components.

⑦ alumina ceramic cyclone for the oil field;
