Zirconia oxide tube offers chemical and corrosion resistance to temperatures well above the melting point of Alumina oxide. Zirconia oxide tubes are very high strength, hardness and particularly toughness. In addition the material has low thermal conductivity and is an ionic conductor above 600°C. Zirconia oxide tube has lead to applications in oxygen sensors. Specially formulated for wire drawing applications. This fine-grained zirconia ceramic provides extreme Hardness, an exceptionally smooth wire drawing surface and
excellent corrosion resistance.
Specifications
Hardness
Specially formulated, zirconia ceramic is the most man-made material for wear applications such as wire drawing capstans.
Corrosion Resistance
Specially formulated, zirconia ceramic is highly resistance to attack by corrosion problems(chemical contents used in processing of wire drawing).
The corrosion resistance fo zirconia ceramic is far superior to metal.
Surface Finish
The superior surface by high polish processing result in high quality of the drawn wire plus extended die life.
a) Normal polish Ra 0.9-1.0μm
b) Fine polish Ra 0.4-0.6μm
c) Diamond polish Ra 0.1μm
Forming methods includes
1,drying pressing
2,isostatic pressing
3,hot pressing casting
