Material Introdution
Aluminum Oxide Ceramic, commonly known as Alumina, is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, excellent electrical insulated, corrosion resistance, and bioinertness. Additionally, it can be highly polished making it useful for precision sealing applications like pumps and pistons. Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is the most commonly used type of advanced ceramic and is available in purities ranging from 90% to 99.8%.
