Alumina Multi Hole Ceramic Pipe and Tube
Alumina Multi Hole Ceramic Pipe and Tube is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once fired and sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness.Additionally, it can be highly polished, making it useful for a wide range of applications.
1.Alumina is an excellent high temperature ceramic material due to its high temperature stability and thermal conductivity.
2.Purities ranging from 95 99.9%.
3.Different types of Alumina including: Injection molded, die pressed, isosostatically pressed, slip cast, and extruded.
