Industry High-temperature Technical Zirconia Ceramic Tube

Industry High-temperature Technical Zirconia Ceramic Tube

The main features of zirconia ceramic tube

1. Can withstand higher temperatures up to 2400° under vacuum or reduced atmospheres

2. Excellent wear and abrasive resistance, much higher 276 times than stainless steel

3. Much higher density than most of technical and advanced ceramics, over than 6 g/cm3

4. Various complicated design production capability with tighten tolerance, precise dimensions
5. Exceptional high hardness, over than 1300 MPa for Vicker hardness, it leads to high wear resistance

6. Low thermal conductivity, less than 3 W/m.k at room temperature, so it can couple with metal well
7. Exceptional fracture toughness than almost advance ceramics, reaches up to 8 Mpa m1/2
8. Chemical inertness which can withstand most of acids and alkali, aging resistance and not rust forever 
9. Resistance to molten metals and avoid any metal residual on surface due to an extraordinary melting point

Description of zironia ceramic tube

Zirconia (ZrO2) is an extremely tough ceramic with a hardness of >9 Mohs which makes it and exceptional material for extreme wear, superb mechanical strength, high temperature and harsh environment applications. Zirconia ceramics have remarkable properties of strength, hardness and wear resistance in addition to withstanding attack from molten metal, organic solvents, acids and alkalis. They can also withstand high temperatures for long periods even under severe mechanical stress.

With our state-of-the-art and comprehensive in-housing precision machines, we are capable of working with different level accuracy ceramic tubes per customers' need from general tolerance to ultra-precision grade, also the surface finish, like polishing, glazing and metalizing for ceramic to metal brazing can be done at home.

Additionally, we also manufacture alumina ceramic tube, silicon carbide tube, silicon nitride tube, aluminum nitride tube in various designs.Whatever, it's a prototyping case or high volume demand, we could help your business.
