The stuff seems to be virtually unknown in the west. You look on reputable distributors, they've got leaded, and they've got tin or tin silver, and they've got the tin bismuth eutectic (58% bismuth, 42% tin), but at138C the melting point is way too low and it's said to be brittle as well. Hell, it's easier to find solder containing gold from ...
