High hardness anti-corrosion for industrial alumina ceramic plates/parts
Alumina, also known as Aluminum Oxide, 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.
