The newer solders for solding pipe are supposed to be lead free, but I
don't recall the metal(s) that are being substituted. Electronics solder
is typically 60/40 or preferable 63/37. The first number is the
percentage of tin and the second number is the percentage of lead. 63/37
is the preferrable solder to use because it is eutectic, basically no
temperature range between liquid and solid.
