For those that dont know, I repair a lot of dead hardware, what is beyond fixing I scrap.
Yesterday I melted down a hand full of old zalman full coper heatsinks. They all had broken fans and mounting tabs and so on.
Anway there were two heatsinks the stood out to me as they contained almost no copper at all.
These too

The pipes were copper, but the rest of both heat sinks were thickly copper pated aluminum. 😠
if I recall both sinks were avertized as haveing aluminum fins and the rest being copper.
Now this is not the first time i seen this, having melted alot of junk heatsinks I can tell you most copper heat sinks art even copper at all. I melted a few koolance nickel plated copper water black that were not copper but brass that was nickel plated. But I was able to to burn the zinc out of it. 😀
I wish I had photos to back up my words. But keep an eye out when buying heatsinks. Not all copper heatsinks are copper.
Next time I meld down some junk heat sinks ill be sure to post photos. I think I have some older msi vga heatsinks that are fake copper. MSI used alot if fake capper heatsinks around 2002-2004.
Edit: ill post some photos latter today on how to spot fake copper heatsinks.
