Alumina ceramic tube/pipe/rod/roller
Product Introduction

Aluminum oxide is also known as Alumina (Al2O3) in short, it is a major engineering ceramic material for functional and structural purposes. It offers a combination of good mechanical properties and some unique electrical properties leading to a wide range of applications in various fields. Alumina can be produced in a range of purities with additives designed to enhance properties, such as zirconia toughed alumina (ZTA). A wide variety of ceramic processing methods can be applied including machining or net-shape forming to produce a wide variety of sizes and shapes of component.

Alumina Tubes as a standard ceramic product. Alumina can take temperatures up to 1650°C, having extremely high temperature stability, chemical corrosion resistance, and high wear and abrasion resistance.

We offer an enhanced range of 99% alumina tubes.
