Yes there are many alloys of solder. 60/40 was the standard for some
time but was replaced 20 years ago by 63/37. That is the only tin/lead
ratio that is eutectic and has been the industry standard for all
soldering AFAIK, for at least 20 years. You may have used 80/20 for some
reason, but it certainly isn't eutectic.


I never claimed that it was.
