Computer heat sinks

They are most definitly aluminum/copper radiators. Also, take a rasp to each one as some may be entirely copper (#2 copper).

Please review the following thread:

Ewasted #6 post clearly says they are different commodities as does post #15 (HT1).

E-wasted deals with this stuff on a large and continuous basis.

HT1 worked in a yard and seemed to know the ins and outs fairly well. You should review is post "HT1 is departing"

I would tend to agree with them.

I have a hard time understanding why they are not considered ACR. I have a stack of AC coils and there is no difference in the materials they are both made of. The fins on heat sinks are 6063 aluminum, which is better than just 6061. When the giant melt furnace is loaded with ACRs to refine, they are going to skim off the aluminum first and then melt the copper.

The important thing to remember is that it doesn't matter what we think. If the yard you are dealing with (or for that matter, the buyer they are selling to) is unwilling to buy them as ACR, then there is no sense arguing with them. You have 2 choices, take what they offer or put it back in your vehicle and find somewhere else to sell it.
