Different Sizes Wear Resistance High Purity Alumina Ceramic Ring
Description:
Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits.Alumina ceramics have good conductivity, mechanical strength and high temperature resistance.It is important to note that ultrasonic washing is required.Alumina ceramics is a widely used ceramics, because of its superior performance, has been more and more widely used in modern society, to meet the needs of daily use and special performance.
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.
