Product Description

Alumina is the most mature engineering ceramics, it provides excellent electrical insulation properties, high hardness and wear resistance but relatively low strength and fracture toughness.It is used to require high wear resistance, good corrosion resistance and pressure.Because of its insulation performance, is often used in electronic products. 

Alumina ceramic screws also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts.

Additionally, alumina ceramic screws find many uses in high voltage applications due to their non-conductive electrical properties.
