Are there any other materials with better thermal conductivity? Silver (429 W/(m·K)) has a higher thermal conductivity than gold (318 W/(m·K)) or copper (401 W/(m·K)) . Other materials with even higher thermal conductivity are: Diamond (900 – 2320W/(m·K)) and Graphene (4840-5300 W/(m·K)) . Source: See Wikipedia’s Thermal Conductivity Table

Thermal Conductivity of Metals: Uses. Based on their rate of conduction, metals are classified and used for particular applications. If a metal has high thermal conductivity, then it is used in heat sink applications. On the other hand, if the metal has low thermal conductivity, then it is used in thermal insulation applications.
Thermal conductivity of materials is temperature dependent. Metals with high thermal conductivity, e.g. copper, exhibit high electrical conductivity. The heat generated in high thermal conductivity materials is rapidly conducted away from the region of the weld. For metallic materials, the electrical and thermal conductivity correlate ...
At the same time, a model based on the ballistic-diffusive effective medium model was established to calculate the lattice thermal conductivity of a hollow nanowire. In the study of copper hollow nanowires, it turns out that: model results of the lattice thermal conductivity agree with results obtained by molecular dynamics.
60. The thermal conductivity of aluminum is 238 J/s·m·°C and of copper is 397 J/s·m·°C. A rod of each material is used as a heat conductor. If the rods have the same geometry and are used between the same temperature differences for the same time interval, what is the ratio of the heat transferred by the aluminum to the heat transferred by the copper?

Table 1: Thermal conductivity of the materials involved Another advantage of copper and the circuit board base material FR4 are the thermal expansion properties (Table 2): Especially in connection with ceramic LEDs, circuit boards based on copper or FR4 have a high resistance to thermal stresses, which depend on environmental or operating conditions and others Temperature cycles, such as for ...
Electrical conductivity tells us how well a material will allow electricity to travel through it. Many people think of copper wires as something that has great electrical conductivity. Thermal conductivity tells us the ease upon which thermal energy (heat for most purposes) can move through a material. Some materials like metals allow heat to travel through them quite quickly.
Thermal Conductivity of Metals. Metals are solids and as such they possess crystalline structure where the ions (nuclei with their surrounding shells of core electrons) occupy translationally equivalent positions in the crystal lattice.Metals in general have high electrical conductivity, high thermal conductivity, and high density.Accordingly, transport of thermal energy may be due to two effects:
