Product Introduction

Alumina ceramic (also called al2o3 or aluminum oxide ceramic) is made of raw material aluminum oxide. Alumina is a ceramic material with high thermal conductivity, compressive strength, high temperature resisitance and thermal shock resistance.

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.
