First, a list of "similar" alloys (composition in percentages):
Manganese bronze (ASTM 138 )
Cu 58.5, Zn 39.2, Fe 1.0, Sn 1.0, Mn 0.3
And so far that is the only one with iron, tin, AND copper.
Here are some links to aid in the search and comparison to steels:

If you are wondering why copper based alloys, it is because of the amount of copper that goes into AA and the fact that I have not found an alloy based from tin or iron that has all of those metals in it.
