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.
