Wiring
Options
- Copper
- Silver
- Gold (too expensive) or aluminum
You can also do a copper wire with a gold/silver platting
| Material | Conductivity (relative to copper = 100%) | Notes |
|---|---|---|
| Copper | 100% | Most common; good balance of cost and conductivity |
| Silver | 106% | Best conductor, but expensive |
| Aluminum | ~61% | Lightweight, cheaper, used in power lines |
| Gold | ~70% | Resists corrosion; used in electronics |
| Steel | ~10% | Strong but poor conductor; used when strength is more important than conductivity |
