When sourcing bulk copper wire, one of the first decisions procurement managers face is whether to select solid copper wire or stranded copper wire.
Both types serve specific industrial applications. Choosing the right format affects:
- Performance
- Installation
- Durability
- Cost
- Safety
In this guide, Identa Group breaks down the differences between stranded and solid copper wire — helping global buyers make the right technical and financial decision.
Understanding the Two Types of Copper Wire
🔸 Solid Copper Wire
- Single continuous copper conductor
- Typically made from EC Grade 99.90%-99.99% copper
- Excellent for:
- Permanent installations
- Low-flex applications
- Power distribution
- Building wiring
🔸 Stranded Copper Wire
- Composed of multiple thinner copper strands twisted together
- Retains high conductivity (100–101% IACS)
- Excellent for:
- High-flex installations
- Machinery and robotics
- Automotive and marine wiring
- Renewable energy projects

🔬 Conductivity Comparison
| Wire Type | Typical Conductivity |
|---|---|
| Solid Wire | 101% IACS |
| Stranded Wire | 99–100% IACS (slight loss due to air gaps between strands) |
✅ Both formats meet export standards when supplied by certified manufacturers like Identa Group.
