Frequently asked questions
What is copper's thermal conductivity in W/m/K?
Copper has a thermal conductivity of 401 W/m/K, making it one of the best heat-conducting metals.
Why is copper such a good conductor of heat?
Copper's atoms are packed closely together, letting electrons pass between adjacent atoms with relative ease.
