Thanks everybody for encouraging me to take my scrap aluminum siding to the
metal scrap dealer (instead of my wife's kiln). I also have been saving
aluminum window frames, screen door frames and ladders. Are these also not
ideal for foundry work? Should I throw them on the truck?

Thanks again,

Ivan Vegvary

Yes. The surface-to-volume is not as bad, but they're still extruded
and you're better off using a cast alloy.

When you throw them on the truck keep them separate. They are handled
differently at the scrap yard.

Don't forget to take the die cast corners out of the doors, and I seem
to recall steel one in some windows.

you can melt the aluminium but the anodising remains as a hard crust
that must be dredged out of the crucible or the casting will be
ruined.
the anodising has amazing strength.

Suitable only for casting anything that will never be machined.

Think chewing gum. On a warm day. About as nice to machine.

Know anyone that works on cars? Aluminum cylinder heads are good
casting alloy.

If you are going to cast with scrap, learn to screen for magnesium, too.

Vinegar on a freshly scraped area of mag. turns a smutty purpleish color.

Hi Ivan,
I happen to have a 16 lb ingot of fresh 356 aluminum casting alloy that
I bought from Budget http://budgetcastingsupply.com/Metals.php.
I will saw it in two and pop it into a flat rate box for you.
It is yours for the cost of shipping. ~9 bux.

take a piece of copper pipe and stir the puddle with it.
it will disolve into the melt quite readily.
ruff as guts and dont overdo it.
the 20xx series aluminium alloys have copper added and have
substantially improved machinability.

experiment.
