Oh, wait ... (senior moment): I use Linotype lead for hammers, it is
harder.
4-12-84 tin antimony and lead alloy.
I don't think that wheel weights are hard (why would they be?).

They are. They are generally 0.5% antimony and 0.25% arsenic - the
rest being lead - and they are heat treated for hardness.
