    don't know the answer but I would compare a few more manufacturers. whoever's numbers are the farthest out of wack are either bad at math, Geniuses or liars.

    One thing to note is the composition is different.

    96% tin, 4% silver.

    I've never had a "lead free" joint come apart.
    The copper will break and tear before the joint does.
