No, (nearly) all metals have different thermal conductivity, since they all have different atomic/molecular structures.

Why do different materials heat up at different rate?
usually metals or conductors get the heat energy from the heat. the heat transfer the particles in the conductors which causes it to heat up in a faster rate to get it hot.
What does conduction of different metals mean?
it means the rate transfer of heat through this metal and coductivity is the measure of this abillity
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What does an insulator do to the rate of heat transfer?
It reduces the rate of transfer.
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.
How is the average rate of heat transfer calculated?
when is heat transferred?
Why are night storage heaters made of ceramic?
This is because ceramic generally has a very low heat transfer rate - if it is hot, it will stay hot for hours because the energy does not dissipate all that fast. In contrast, metals dissipate heat energy rapidly, which is why cold beverages are often put into metal cans - they become cool relatively rapidly.
How does heat energy affect the movement of particles?
If you take a vessel full of water and heat it with the spirit lamp you will find that when the heat energy is continuously transferred the molecules in the vessel gets the energy as a result they move in a faster rate. The transfer of heat energy to any molecules increases its kinetic energy.
How can heat transfer be promoted?
Answer is within heat transfer equationconduction = (k.A.dT/x)dtConvection = (h.A.dT)dtRadiation = s.e.AdT4.dtIncrease of conductivity (k) or heat transfer coefficient (h) or area (A) or temperature difference (dT) or contact time (t) or emissivity (e) allow for higher amount of energy to transfer.Reduce of transfer distance (x) increase rate of energy transfer.Increase flow rate to boost convection heat transfer (fluid)Increase surface area of contact (solid - fluid)Design heat exchanger in counter current flow (fluid)Prolong retention time (higher contact time -> more heat can transfer)Change of heat transfer medium (better thermal conductor medium)Use of heat pump (promote higher temperature difference yield better heat transfer)Coat surface with black colour (higher emissivity promote radiation heat transfer)
What can slow the movement of heat energy from a warmer object to a cooler object?
Transfer of heat can be slow down by increase insulation. For radiation heat transfer, colour coating could reduce rate of radiation in the same manner as insulation. Reduce surface area of heat transfer (or area of contact) can also reduce rate of heat transfer.
What is the rate of energy transfer called?
It's Power.
