Product description

Product Description:

 High Hardness Alumina Ceramic Washer With High Temperature



Ceramic Sleeve Washer / Ceramic Sleeve Bushing are one of the most thermally resistant washers available. Due to their outstanding thermal resiustance, alumina ceramic washers are geared for the most demanding high temperature applications. Alumina ceramic washers also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts. Additionally, alumina ceramic washers find many uses in high voltage applications due to their non-conductive electrical properties.

Alumina ceramic washers are available in both metric and standard sizes. Please contact us if you have any questions about the properties or availability of our ceramic washers.

washers made from customer specified ceramic grades or custom dimensions are available upon request.

Washer Types: Flat washers
