Ceramic Round Double Bore Tubes
Ceramic Round Four Bore Tubes
Ceramic Solid Rods
Ceramic Solid Rods
Ceramic Oval Double Bore Tubes
Tube Seals


Brief Description

The ceramic  tubes, thermocouple protection tubes and insulating rods produced by INNOVACERA are made of alumina ceramic (Al2O3). Alumina ceramic have a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. The max. using termperature of  these tubes & rods can be up to 1800 °C. They are an excellent choice in furnace and temperature measurement whenever safety and stability are required.

Product Description


Alumina is the best-known advanced ceramic material, is widely used in automotive, petro-chemical, fluid control,material transfer, Industry,electrical and electronic, semiconductor.Sapphire is single-crystal alumina.

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
