Alumina Double Bore Tubes

Alumina Ceramic Tube refers to a type of ceramic material made from alumina (Al2O3) which has excellent hardness, high-temperature resistance, and corrosion resistance properties. These tubes are commonly used in industrial applications such as furnace and thermocouple protection tubes, medical implants, and electrical insulators. Alumina ceramic tubes are also known for their excellent wear and abrasion resistance.
