i use my trusty punch, hammer and vise, i set the heat sink on top of the vise with a gap wide enough for the copper to fall out, center the punch and about 2 whacks, ive only had about 20 of these, i wish they were all this style, the yard manager said he never seen any before

Do you know if these are pure copper or mixed with something else?
