PCD vs. Tungsten Carbide – Comparison
PCD dies offer clear advantages in high-volume, precision non-ferrous drawing, while carbide remains economical for harder/larger applications.
| Feature | Relink PCD Dies | Tungsten Carbide Dies |
|---|---|---|
| Die Life (non-ferrous) | 50–200× longer | Standard baseline |
| Wire Surface Finish | Excellent, smooth, consistent | Good, but degrades faster |
| Wear Pattern | Highly uniform & predictable | More variable |
| Thermal Conductivity | Very high (excellent heat dissipation) | Moderate |
| Hardness | Extremely high (diamond level) | High |
| Toughness/Impact Resistance | Good (improved over natural diamond) | Excellent |
| Best For | High-speed precision, long runs, copper/aluminum | Ferrous/hard wires, large diameters, cost-sensitive |
| Initial Cost | Higher | Lower |
| Cost per Meter Drawn | Significantly lower in high volume | Higher over time |
