    Aluminum identification

    Do any of you guys know of a book that has an extensive list of the different grades of aluminum and methods/visualizations of identifying each? Next to an ?XRD? gun I have never seen a comprehensive list of anything except cats.

    I'd say "No" too. The only distinctions they make at the yard is - Sheet (or Old Sheet), Cast and Extrusion. Pretty simple.
    People may laugh at me, but that's ok. I laugh all the way to the bank.

    Alright guys, thanks for the input. I thought maybe they paid a different price for all the types. But since they have their own classifications, I won't worry about it.

    When I was younger, I had brought a big gaylord full of mixed clean aluminum sheet metal. It was the scraps left over from a stamping machine, and they were all different grades of aluminum. Some was maybe 6061, 6063, 2219, 1350 ect... When I brought it into the yard, which at the time was advertising a price of .35 cents per pound (i think), they tried to convince me that the price of the aluminum was much less because they needed to "sort" through all of the different grades of aluminum.

    That, of course, was complete bull****. I didn't realize it at the time, and for about 4 months I tired to figure out how that type of scrap was identified and sorted. But they were lying completely. They never sort out aluminum. It would be completely fruitless if they did. They were just trying to rip me off.

    The only aluminum worth keeping to the side, is aluminum rims, which are made of a precipitation hardend alloy. I think some yard may actually try to resell the rims (especially if you sell them as a set) making 1000% on what they pay you.

    If you want to make more money on aluminum scrap, and you know what alloy you have, try to sell it to a metal supply shop. I know a couple places near me want larger scraps, because they can sell them to customers looking for that type of stuff.
