I thought the reason 63/37 (or whatever the precise ratio is - I think
it's something like 63.7/36.3, no?) was preferred was that it had a
melting _point_ rather than a melting _range_. (Whether this is tied
to its being the eutectic mixture is something I'm not enough of an
alloy scientist to know.)
