I never thought of casting an aluminum hammer form, and I have a foundry in my sculpture studio.

The one thing you have to account for is shrinkage. I'm not sure what it is for aluminum as I cast mostly bronze. I can imagine making a pattern a bit over sized from something soft, plaster or white pine, casting it in sand, and doing the final machining of the edges on a router table.

Many is the time I have beat something out of stainless sheet metal and wished I had a hammer form, but wooden hammer forms and stainless don't go well together. (About the only way to form stainless is when it's red hot.)
