Main features of alumina ceramic tube
1. Outstanding wear resistance, over 276 times in comparison with
stainless steel
2. Great mechanical properties, hardness, compressive and flexural
strength are much higher stainless steel
3. Exceptional corrosion resistance, it can withstand various
strong acid and alkali, like HF, H2SO4
4. Extraordinary electrical insulation, it always us in many high
voltage, high-current application
