Thermal Conductivity of Materials
Comprehensive Guide
Compare MaterialsMaterial selection for thermal management requiere understanding conductivity valores. Desde heat sinks un/una insulation, choosing el/la right material depends on whether tu querer un/una conduct o block heat.
Materials by Application
| Application | Material | k (W/m·K) |
|---|---|---|
| Heat sinks | Copper/Aluminum | 205-400 |
| Cookware | Copper, Cast iron | 50-400 |
| Thermal interface | Thermal paste | 1-10 |
| Electronics PCB | FR-4 | 0.3 |
| Building walls | Concrete | 1.0-1.8 |
| Insulation | Polyurethane foam | 0.02-0.03 |
Conclusion
Material thermal conductivity spans five orders of magnitude—desde diamond at 1000+ W/m·K un/una aerogel at 0.01. Engineers balance conductivity with cost, weight, y otro properties. Copper excels for heat transfer; foams excel for insulation; ceramics bridge ambos worlds for especializado aplicaciones.
