The description of alumina ceramic tube
Aluminum Oxide, also known as Alumina (Al2O3) is one of most hard advanced technical ceramic material, which commonly used in a variety of industry applications. Alumina ceramic offers many excellent properties, including high temperature resistance, super wear resistance, corrosion resistance,erosion levels, high electrical insulation, as well as it features cost performance advantage. With the purity increases of alumina, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.
Alumina Ceramic Tubes is a most popular engineering and structure ceramic parts, but it plays a very important role. our facility has many selections of stocks with standard dimensions. Our vast, readily-available inventory allows us to supply our customer’s ceramic tube needs immediately, even for hard-to-find or specialty products. Except for standard design both ends open ceramic tube, we also produce one end closed ceramic tube, ceramic tube with flange, square ceramic tube, rectangular ceramic tube, hex ceramic tube, ceramic tube with double-bores, tri-bores tube.
Remark:
We are able to achieve a variety of special requirement of ceramic tubes, including different materials,
different designs, different geometries.
