    But it was, grasshopper. You paid too much, because you bought it from a
    hobby supplier.
     
  2. AH-SO! At last we're communicating. Yep, usenet is tough that way
    Fascinating. Perhaps someone, somewhere will have an explanation.
     
  3. I wasn't mislead. Given the differenc in price, it was obvious
    Actually, I bought the solder at least 20 years ago, and I believe it came
    from an electronics-supply store, not a "hobby supplier". I also paid less
    than $10.

    As a side note, the wholesale pricing of solder also seems to be heavily
    volume driven. A small distributor to hobbyists might buy a couple of
    hundred pounds at a time, while a large industrial distributor buys tens
    of thousands. They get a huge discount for that, and can easily pass
    that savings on to their customers.

    But we still don't have an answer to the question of why there is such a
    wide disparity in the /relative/ pricing of 60/40 and eutectic solders.
     
  6. Because 60/40 is just solder, while 63/37 solder is an allowed under special
    circumstances lead-free replacement and needs certification?

    I know it's not lead free, but it's the solder you use when you have to
    use leaded solder under lead free regulations.

    At the risk of misunderstanding you yet again, and mis-responding,
    here's my shot at that:

    Smaller distributors play on the "new and improved" perception that
    someone up-thread mentioned, so they mark up the 63/37 more.

    Larger industrial distributors play it a little straighter, with more
    equal markups. But my side note could actually play into this, too: If
    my supplier sells 10 times as much 63/37 as he does 60/40, then he
    obviously buys 10 times as much, so Kester gives him a better price
    break.

    Must be cocktail hour where you are, Geoff. Either that or I'm still
    hungover and don't know it.

    The difference existed at least 30 years ago, when I bought my first roll of
    eutectic.

    No, you're not misunderstanding, and what you say is logical. But... This
    disparity existed 30 years ago, when I first bought a roll of eutectic
    solder. At that time, eutectic was less-common and less asked-for. That
    /might/ explain the difference.
     
  11. Solder prices for single pound lots are all over the map- they change
    with voltatile metal prices and some distributors may have old stock.

    There's been roughly a 4:1 price range in lead and 2.5:1 in tin over
    the past three years. Currently tin costs about 10x as much as lead,
    so you'd expect about a 10-11% price difference due to cost of the
    metals. At current prices there's around $5.30 worth of metals in a
    pound of solder, of which only 30 cents or so is lead. There's also
    the plastic spool, the cardboard box and 10-15 grams of flux.

    No wonder I haven't seen those $4.95/lb. bar solder sales lately. I used
    to wait for those and stock up a couple hundred pounds for the soldering
    machine.
