most of the time heatsinks do not use a solder other than the material they are made of. the only thing you need to watch for is that the metal does not have a melting point of anywhere near 200c, which copper is over 1000c, and aluminum is around 600, so you should be fine with almost any heatsink
Hi thanks for your response, my concern is with the peltiers and effectively removing that much heat from one side of the Peltier itself. Do you have any experience in a suitable heat sink that will fit the space requirements mentioned and be capable or moving the amount of heat?
