In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature.

Copper provides the highest thermal conductivity among non-noble metals and is therefore fast heating with unparalleled heat distribution (see: Copper in heat exchangers). Pots and pans are cold-formed from copper sheets of various thicknesses, with those in excess of 2.5 mm considered commercial (or extra-fort ) grade.
As a rule of thumb when substituting glass in a recipe that calls for metal, chef David suggests lowering the temperature by up to 25°F and extending the baking time by five to 15 minutes, and ...
Chromium is a relatively inert metal and does not rust or react as easily as plain carbon steel. This is what makes it an exceptional material for cooking. It is also fairly inexpensive, but does not have a very high thermal conductivity. From a surface standpoint, this is because of the thin layer of chromium oxide that is formed on the surface.
The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.

Thermal conductivity, frequently represented by k, is a property that relates the rate of heat loss per unit area of a material to its rate of change of temperature. Essentially, it is a value that accounts for any property of the material that could change the way it conducts heat. [ 1 ]
