Crushed or shredded soda can for melting aluminium metal?

(OP)
Which condition is the best before melting aluminium from soda cans ?
Does shredded aluminium soda can produce slag than crushed ?

RE: Crushed or shredded soda can for melting aluminium metal?

It won't matter much when it is liquid.

RE: Crushed or shredded soda can for melting aluminium metal?

Crushed cans can't be washed before melting if that makes a difference.

RE: Crushed or shredded soda can for melting aluminium metal?

And water can be trapped in crushed cans witch can cause steam explosion issues.
If you charge cold and melt, then crushed would be fine.
But any additions to the melt should either be shredded or crushed that have been baked well.

RE: Crushed or shredded soda can for melting aluminium metal?

Certainly water is a problem - but notice that shredding still requires a heat cycle to drive moisture out which might be remains of the contents - this moves it to likely candy-temperature problem, boiling hot isn't enough.

Steam explosions in aluminum are no joke - Here's an extreme example of water exposure: https://youtu.be/dAHolupCEkc?t=119 but if that happens during the melting process it can also produce a red-hot aluminum geyser.
