Copper or aluminum?
« on: March 01, 2008, 11:27:50 AM »
Well i wonder if copper or aluminum has better heat transfer. For example what is better to use for a water cooling device for CPU? Copper or ALu?

Thermal Conductivities of Some Common Metals
MetalThermal Conductivity, k (in unit of W/m·K)
Aluminum205.0
Brass109.0
Copper385.0
Lead34.7
Mercury8.3
Silver406.0
Steel50.2


I hope this helps

Copper of course. Aluminum is used wherever we want light construction. But i think you do not have any limitation to weight do you?

Well you can use silver as well. Will be better than copper. The only problem will be that the radiator will be more expensive than the computer. Or maybe more. lolol  :) :) :) :)

I think there are some ready made and very good stuff around the net in a good price. CNC grooved and machined with o-ring and see-through cover. Very nice!

I thought so. And i beleive copper is much more easy to work with with home materials. Like, soldring for example.

Yes it is. A little bit expensive though... :-\ :-\
But it worths it!

pffff. I will not need one ton copper. It is not that expensive...

"Copper has a high electrical and thermal conductivity, second only to silver among pure metals"
From wikipedia but also found on any serious encyclopedia or technicall book

nuff said i think  :P

It is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly-exposed surface has a pinkish or peachy color. Aluminum is remarkable for its ability to resist corrosion due to the phenomenon of passivisation and the metal's low density. so, I guess, they are both good.

They are both good but for heat transfering copper is superior.

I think it has almost half the heat resistance than the aluminum...
