High Hardness Wear Resistance Pure Alumina Ceramics Tube
Description:
Alumina(Aluminum Oxide, Al2O3) is the most extensively used
advanced ceramic material due to their outstanding property
characteristics and cost-effective advantage. As with the purity
increases, both wear resistance and corrosion resistance also
increases, so alumina are grouped together based on purity levels,
including 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina,
99.9% alumina.
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.
