High Thermal Conductivity Metal Alloy
High Thermal Conductivity Metal Alloy
(OP)
I need a metal (alloy) with the highest possible thermal conductivity to use as heat exchanger. I have tried pure copper, but I noticed severe temperature corrosion at 450°C. I have also tried nickel plated copper, but the nickel comes loose at sharp edges.
Does anyone have a recommendation for a metal alloy with excellent thermal conductivity (preferably the same as copper) and high temperature corrosion resistance ? The metal (alloy) will be used as heat exchanger and should not be excessively expensive.
Many thanks for your help.

You need to look at the CDA web site and see if there are any Cu alloys that are usable in your temp range. My guess is that they will have Ni and Cr in them and their TC will be less than 1/4 of pure Cu.

Here are a couple of ideas if you have to get away from Cu and go to a Cu alloy.
Wolverine Tube has various Cu alloy finned tubes available that might work. Using fins will mediagate some of the loss in thermal conductivity from the Cu tubes.

Ener-Fin makes a Al finned Cu tube that might work and again I don't think you will loose much heat transfer.

If you have to get away from Cu or Cu alloys altogather Fin-Fin is another approach to enhance the heat transfer of other metals.

The heat transfer will be considerably less than Cu but the heat resistance much better and as has been pointed out, geometry can be a large factor in heat transfer. Thinner tube walls plus fins can be used to take advantage of the strength & heat resistance to heat transfer ratio.

I found an interesting content regarding quotation on metal injection molding parts on
http://omnexus.com/rd/?rd=213&lr=postengtips
You might be able to find someone there who can quote/advise on the best material/alloy to use.
