Nextgen Advanced Materials supplies high-quality multi-bore alumina tube in different sizes and specification. Customized production is available.
As the professional manufacture, we would like to provide you high quality Nextgen Multi-bore Alumina Tube. Multi-bore alumina tube is made of a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. Alumina ceramic also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina is high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing.
