Product Description
Specially formulated for wire drawing applications. This fine-grained zirconia ceramic
provides extreme Hardness, an exceptionally smooth wire drawing surface and
excellent corrosion resistance.
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.
Originality
Providing excellent hardness, corrosion resistance, superior surface finish, ceramic capstans attained worldwide estimation in wire drawing industries field.
