בדיל
'bedil' is typically translated as “tin”.
This meaning is somewhat dubious. Bedil is actually the same root word as hebedil, which infers that some kind of metal that requires a separation process of smelting is implied, but certainly does not imply “tin” specifically.
For a thorough examination of various metals in the ancient Hebrew texts and how this ties in with the archaeological record, see metallurgy.
