Specifications

Ceramic rings
1.high wear resistance
2.excellent corrosion resistance
3.specially formulated
4.Long working life

Industrial wire drawing ceramic rings, excellent hardness and wear resistance,fine polished  

Features:

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 fo 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.
