    Not thrilled that it is a lead alloy. Just when we are starting to get rid of all the lead in our communities, this would put it back as part of critical infrastructure everywhere…

      You probably shouldn’t look up what most solder is made with, then.

      Lead never went away, and it never will. It just stopped being put in things like gas and paint.

        Leas-free solder is now the standard due to RoHS, at least in Europe. It doesn’t stick as well as Pb-Sn solder though, annoyingly.

          The transition to lead free solder (and lack of experience using it) led to the XBox 360 red ring of death issues, Playstation 3 yellow light of death, and nVidia 8000 series no video failures.

          And indeed the transition happened a long time ago.

      As others have mentioned lead is still everywhere. All our combustion car batteries are still lead/acid batteries, but if what /u/[email protected] mentioned the paper claims is true, the method for inducing superconductivity in the metal could possibly be used to create other lead free ones.

      Got bad news for you about wheel weights…

        Those are increasingly lead free to my knowledge. I’m not sure exactly how free, and it does vary by location and business.

        I haven’t seen a lead wheel weight in the US in years. They’re illegal in California, maybe other states too.
