I'm looking for information about lead-substitute metal
alloys that have the following characteristics:
1) heavy
2) soft (not brittle)
3) low melting point
4) inexpensive
5) easily obtained/produced
6) castable (for small mold pouring with fine detail)
7) non-toxic (important...this alloy would be for use
   in areas where lead is restricted to protect the
   environment).  

Lead meets the first 6 of these 7 criteria, but the 7th is
perhaps the most important.  I have heard certain zinc alloys
are being used, but I do not have much information about them.
From what I understand, these alloys are relatively expensive,
and do not pour well into molds with any amount of detail.  If
you have any information or ideas, or even if you have just
the slightest hint of a clue, I'd be grateful to hear from you.  

Thanks,
Jeff.
