If you melt the aluminum away from the steel and iron inserts, it goes from irony al to cast aluminum.
In this day and age that's like 5cents a pound to twenty cents a pound, at least around here.
In the good only days you would have gone from 20 cents a pound to maybe 70 cents a pounds.
I could almost see it being worthwhile, it would make an ass load of smoke though, maybe in the country.
It might not be a bad idea, if you have faith in scrap prices. Run around picking up scrap irony aluminum for next to
nothing and convert it to nice stackable ingots for the future. Hmmm... how much aluminium could you fit in a
shipping container... :-)
