Drawing die options

Several drawing die materials may be available depending on drawing needs. The table below provides an overview of materials available. Relative durability and price will help determining which one will be ideal for your particular application. Please discuss your drawing needs with a KIWI® Wire Die expert to make sure you use the best and most cost-effective wire drawing die.

1. The size range is for indication only. The maximum and minimum size depends on the required drawing die profile. How to check if a certain blank can be used, please ask KIWI® Wire Die for guidance.
2. Relative durability is a comparison to tungsten carbide dies. The durability is for indication only and can differ depending on the drawn wire type, wire condition, lubricant used, and wire drawing conditions.
3. Relative price is a comparison to tungsten carbide dies. The relative price is for indication only and can differ depending on the tolerance, die geometry, casing size and any other requirements.
4. Elastic modulus is measured in GPa, and thermal conductivity in W/mK. More information on elastic modulus and thermal conductivity can be found on Wikipedia.
