Thermal Conductivity of Common Copper Alloys

Copper alloys are known for their high thermal conductivities, which means they are excellent at transferring heat. This property makes them valuable for various applications where efficient heat transfer is essential.

The following tables provide a comprehensive list of thermal conductivity values for different copper alloys, taken at room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
