What are materials that suit themselves to a more rapid heating rate?

My favorite analogy is cooking turkey.

My favorite analogy is cooking turkey. We are coming up on Thanksgiving time. We all know that we have to set the temperature to 350° or so in the oven and then cook the turkey for a couple hours and that's basically the heat ramp up rate inside the meat of the turkey. That's what happens with different metals. Copper is an extremely good conductor of heat and electricity; the copper part is able to withstand a lot more power density on the surface versus a part that is made of steel. Steels have decent thermal conductivity but not as good as copper or aluminum. Steels would have more of a limit on what power density you can put on the surface versus copper which is able to withstand a lot of power density on the surface.
