Térmico Condutividade of Materials
Comprehensive Guia
Compare MaterialsMaterial selection for thermal management requires understanding conductivity values. De heat sinks to insulation, choosing o right material depends on whether you want to conduct ou block heat.
Materials by Aplicação
| Aplicação | Material | k (W/m·K) |
|---|---|---|
| Calor sinks | Copper/Aluminum | 205-400 |
| Cookware | Copper, Cast iron | 50-400 |
| Térmico interface | Térmico paste | 1-10 |
| Electronics PCB | FR-4 | 0.3 |
| Building walls | Concrete | 1.0-1.8 |
| Insulation | Polyurethane foam | 0.02-0.03 |
Conclusão
Material thermal conductivity spans five orders of magnitude—from diamond at 1000+ W/m·K to aerogel at 0.01. Engineers balance conductivity com cost, weight, e outro properties. Copper excels for heat transfer; foams excel for insulation; ceramics bridge ambos worlds for specialized aplicações.
