The high tin content is what leads me to believe that it would likely be bronze in behavior. I'll see what appears with replacing the iron with copper since the two would form a substitutional alloy.
I found another alloy that has iron and tin together.
It is a Phosphor Bronze
I have found that two parts copper and one part tin yields a brittle alloy.
Hey Al, maybe you should consider making bells.
Whoa, I clicked on bells, and saw this link in the page: http://en.wikipedia.org/wiki/Stannite
Stannite ore, smeltable into advanced metal alloy ingots?
