A superb combination of corrosion resistance, temperature stability and non-conductivity
- Exceptional temperature resistance up to 3000°F (1650°C)
- Outstanding corrosion resistance to acids, solvents, salts, and organics
- Excellent electrical & thermal insulator
- High purity
- Alumina ceramic datasheet
Alumina ceramic screws are one of the most thermally resistant screws available. Due to their outstanding thermal resiustance, alumina ceramic screws are geared for the most demanding high temperature applications. 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.
Alumina ceramic screws are available in both metric and standard sizes. Please contact us if you have any questions about the properties or availability of our ceramic screws.
Screws made from customer specified ceramic grades or custom dimensions are available upon request.
Screw Types: Flat Head Screws, Hex Cap Screws, Pan Head Screws, Set Screws, Socket Head Cap Screws
Common Ceramic Grades
Alumina ceramic or Aluminum oxide (Al203) is the most common grade of alumina ceramics and is designated as being 99.8% pure. Alumina is most known for high temperature stability and has a usable temperature limit of 3000°F (1650°C). Alumin has the greatest balance of economy, mechanical and thermal properties.
Various other compositions of alumina ceramic are available upon request.
