As a buyer and seller of scrap metals for 10 years plus here in Indiana these heat sinks are not cast aluminum they are #1 extruded aluminum, .68 cents a pound as of Friday, cast aluminum .51 cent a pound, if they are buying from you as cast they are up grading and getting over on you, the colored one's are also #1 ex as they are anodized. Some of the smaller one's have a metal wire hold down remove it and it's #1 ex if you don't it's a #2 aluminum same price as cast here .51 cent a pound. Just a head's up.
I agree. I get extruded price for the ones that I HAVE to remove or want to remove as in the case of low grade boards. Also, as brassbusterpc stated, no difference in price for anodized. However, some are cast but I usually fail to notice at the time and toss in the extruded bucket.
