Product Description
Customized corundum protective tube alumina ceramic tube
Alumina ceramic protection tubes have good mechanical strength, wear resistance, corrosion resistance and good air tightness, so they are excellent primary protection tubes. Alumina ceramic protection tubes can be used for primary and secondary protection tubes on precious metal (platinum-based) thermocouples.Materials Physical and Chemical Index
