I get the impression that the gradeo of ALI in Ali cans is specific to the cans.
The tabs and the cans are the same grade too.
So when you take the cans, they bail them and send the bails back to the original can manufacturer.
That way there's only one middleman and you get good prices.
If you send the cans to a
foundry etc, they may have to test the moltem ali and add other metals to the mix to get it right.
That costs money.
I think its the same deal with cast ali. The foundry who casts the ali wants 'casting grade Ali' only.
I think that's why there's so many grades of Ali.
Domestic. Cast ali. Àli cans. Extrusion ali. Plus others....
The bestvway to get the best deal is, handle it once only!!!!!!
Pick up the can, shake yo make sure there's nothing in it. Squeeze the can so the sides touch and put it in whtever its going to be taken to tge scrap mtal dealers in.
Two notes here.
1 Guiness beer cans have a plastic ball inside them. Lke a tabletenis ball. It stops the beer from foaming so much.
2. Don't flaten the cans. Flattening is another process and adds to the time handling the cans. It dosn't save much space either. Plus , if you flatten the cans, when they bail the cans up, they don't stick together which is a real pain for the guys who deal with the cans.
By just squeezing the sides in, it saves the space and makes the cans 'lock together' into one big chunk when they bail it up.
We get special prices for Ali cans. There's a smelter who melts them down to billets and they go to the can manufacturer in one go.
