320 pounds of heat sinks....

Here are some photo's of Cu/Al heat sinks I had. I seperated the larger sections of Cu by heating them on a propane "turkey" cooker in a SS basket. All I needed to do was heat them hot enough to melt the solder that holds them together. The ones with the Cu tubing I cut the tubing and sold them as Cu/Al radiators.





Here's a different type.



Here's one that looks like the bottom is Al but the grinder revealed it was Cu.



Best of luck, Mike.
