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.
