Thermal Conductivity of Common Aluminum Alloys
Aluminum alloys have a relatively high thermal conductivity, which means they can transfer heat quickly and efficiently. This makes them ideal for applications where heat dissipation is important, such as heat sinks, radiators, and automotive components.
The following tables provide a list of thermal conductivity values for various aluminum alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
