95 alumina ceramic tube

Advantages of 95 alumina ceramic tube

95 alumina ceramic tubes feature extremely high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance and biological inertness, and are often used in precision sealing applications such as pumps and pistons. Its high temperature stability makes it an excellent high temperature ceramic material. It is the most commonly used type of high-grade ceramic, with purity ranging from 95%-99.5%.

Applications of Alumina

electrical wires and conduits;

Machinery Seal;

machine parts;

High temperature electrical insulators;

High voltage insulators;

Electronic component substrates;

roller and ball bearings;

wear-resistant lining;

semiconductor parts;

Precision shafts and shafts in high wear environments.
