Dataset Summary
CCA vs Copper Weight and Cost Screening Table
A procurement screening table comparing copper clad aluminum and copper by weight, conductivity and qualification risk.
Download CSVData Table
| Option | Relative Weight | Conductivity Logic | Procurement Note |
|---|---|---|---|
| Pure copper | 100% | Reference 100% IACS | Best for compact high-current designs |
| CCA | Approx. 40-55% of copper at same geometry | Typically lower than copper | Best when validated for resistance and termination |
| Aluminum | Approx. 30% of copper at same geometry | Lower conductivity per section | Requires aluminum-compatible joining |
How to Use This Data
- Use for early material selection conversations between engineering and purchasing.
- Do not approve CCA substitution without resistance, joining and standards review.
Assumptions and Limitations
- Relative values are indicative and must be recalculated against final geometry.
- Cost depends on copper price, layer ratio, processing route, quantity and inspection requirements.
