Copper/Aluminum Radiator Heatsinks, do they grade as aluminum/copper heatsinks, they are a little different from the type in the payout rate pictures, thank you for your help.

they are the same, as long as they have both copper and aluminum they all go together no matter what shape and size they are.

You also want to make sure they are clean of any steel, plastic, screws, fans, etc.... If they do have contamination, they will be bought as dirty radiators.
