Zirconia ceramic ring is made of high purity zirconium oxide materials, unlike traditional ceramics that tend to be hard and brittle, zirconia ceramic ring has high strength, wear resistance, and flexibility far beyond those of most other technical ceramics. Zirconia is a very strong technical ceramic with excellent properties in hardness and corrosion resistance, all without the typical property of ceramics brittleness. Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals like steel. Due to zirconia’s properties it is sometimes referred to as the “Ceramic steel”.
1. Hardness
Specially formulated, zirconia ceramic is the most man-made material for wear applications such as wire drawing capstans.
2. 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 for zirconia ceramic is far superior to metal.
3. Surface Finish
The superior surface by high polish processing result in high quality of the drawn wire plus extended die life.
4. Originality
Providing excellent hardness, corrosion resistance, superior surface finish, ceramic capstans attained worldwide estimation in wire drawing industries field.
