1. Thermal conductivity of metals in between 20°c and 800°c

2. Thermal conductivity of liquids

3. Thermal conductivity of gases

---

The thermal conductivity of a material, expressed in kcal/h.m.c or W/m.K is measuring how easily a material is able to transmit heat by conduction.

• Warning 1 : values were not verified individually
• Warning 2 : The data below are thus only for a 1st reference, quick calculation, but no detail design, no guarantee are given upon them.

1. Thermal conductivity of metals in between 20°c and 800°c

In between 20 and 500c :
