Aluminum vs. Copper Fin Stock
Why aluminum dominates 92% of global HVAC market
| Factor | Aluminum | Copper |
|---|---|---|
| Thermal Conductivity | ≈235 W/m·K | ≈398 W/m·K |
| Material Cost | 65–75% LOWER | 3–4× higher |
| Weight | 65–70% LIGHTER | Much heavier (8.96 g/cm³) |
| Service Life (coated) | 8–12 years | 10–15 years |
| Recycling Energy | 95% SAVINGS | Standard |
Conclusion: Aluminum delivers 90% of copper's efficiency at 35% of total cost, making it the optimal choice for mass-market heat exchangers.
