A superb combination of corrosion resistance, temperature stability and non-conductivity

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

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

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

Common Ceramic Grades

Alumina 99.8%

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.
