Alumina Tube, Aluminium Oxide Tube (Al₂O₃ Tube) 95%, OD. 20 mm Packing

The tube is packaged in an inner protective container with inert foam padding to cushion against mechanical impact. It is sealed in a contamination-resistant plastic wrap and clearly labelled for traceability. The packaging supports storage in a cool, dry environment to maintain material properties. Customised packaging options with additional cushioning or compartmentalisation are available upon request.

Additional Information

Alumina ceramics have been extensively researched for their excellent thermal and mechanical performance in harsh environments. The material's microstructure, achieved via controlled sintering, governs its density and strength, making it suitable for applications that demand high thermal stability and structural integrity. Understanding these factors, manufacturers tailor processing parameters to optimise performance and extend the service life of alumina components.

The properties of aluminium oxide also influence its electrical insulation capabilities, which is critical in high-temperature electronics and industrial applications. These ceramics play a significant role in modern engineering systems, providing solutions where conventional materials may fail under extreme operational conditions.
