Casting aluminum in wood ash

Recommended Posts

Just wondering, my neighbor is scrapping aluminum cans and we was wondering if there's any other material readily available, other than sand, in southern South Dakota where we are. Most of our trees are dying and the sand here needs cleaning

Jimmy, welcome aboard from 7500' in SE Wyoming.  Glad to have you.

There is only one way to really find out, experiment.  I would be concerned about wood ash being too light to support the weight of the metal but perhaps if you compressed it considerably.  

What are you thinking about casting?  Aluminum cans are not the best Al alloy for some applications.
