75% alumina ceramic tube is made of alumina ceramic material with 75% Al₂O₃ content, also known as C610 mullite high-alumina ceramic tube.
It features good mechanical strength, excellent electrical insulation property, moderate thermal shock resistance and low dielectric loss. Compared with 95% alumina ceramics, it has a better cost-performance ratio.
