<p>[QUOTE=&quot;-jeffB, post: 1076408, member: 27832&quot;]I&#039;m pretty sure that house wiring has relied on punch contacts and wire nuts for a lot longer than that, at least according to my 1970s-vintage home-improvement books. And electrical solder was always tin-lead, 63/37% for the lowest melting point, 60/40 for cheaper stuff. I think the only thing silver solder was used for was higher mechanical strength, high-temperature stability, and maybe better bonding to certain metals. With high-silver-content solder, you&#039;re really brazing more than soldering. (Thus, the need for an acetylene torch.)</p><p><br /></p><p>A quick check of Wikipedia says that the Japanese have moved mostly to tin-silver-copper solder. Looks like the electronic silver solders are mostly 2.5-3.5% silver, not enough to sharply spike the cost of products, but certainly enough to create demand when you add it up across all the products being made.[/QUOTE]</p><p><br /></p>
