Alumina ceramic is the most common technical material and a relatively traditional ceramic. High purity alumina has excellent performances in electrical insulation, high chemical resistance and low thermal expansion. Multi-bore Alumina Tubes are used to make parts for CVD, ion implants, photolithography, and semiconductor.

The above chart just demonstrates the typical properties of common alumina ceramic we use to produce our alumina parts. Please notice that the properties for customized alumina parts vary due to different processing. ZG Industries, Advanced Ceramics Division provides alumina products according to your specified instruction, or do the best to meet requirements.
-Spare parts for pan-semiconductor equipment (manufacturing equipment such as LCD and LED)
-Insulation
-Wear parts
-General machinery, hydraulic components
-Used as injector tubes, gas nozzles, and insulators.
-High temperature situations & a protector for high-temperature thermal couples.
As a ceramic material, Alumina Tube is quite fragile in a lot of cases. Our Alumina Ceramics are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used, vacuum packing is also engaged for some of the parts.
