Wear Resistant 100mm 2000mm Ceramic Alumina Tube Al2O3
Wear Resistant high purity Ceramic Alumina Tube
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.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.
