  • Tungsten Alloys

    A poster on another board I frequent is thinking about getting tungsten carbide wedding rings is a bit concerned about the rings shattering easily and wants to know what kind of alloy they should look for in a ring. All I know about tungsten carbide alloys is that some of them are nearly indestructible and others are not, but I've no idea which alloy is which. Any recommendations?

    Also, there's a wide variation in prices on websites for rings of the same style. One site will sell a ring for $50, while another site has an identical ring for $250. Any idea as to what could be causing the disparity in prices?

    Maybe better look at titanium alloys?
    G11 Ti is commonly used in jewellery, anodizes in some magnificent peacock colours.

      Just out of curiosity, and not to disparage anyone's personal whims...but why would anyone want a tungsten carbide wedding ring?

        Tell him to forget it. Tungsten carbide alloys are cemented alloys using cobalt as a binder. Cobalt is highly toxic.

            Kinda my point, in a gentle way Evan.
            Maybe mistook W for Ti?
            Don't think pure tungsten is toxic (?) but cemented carbides certainly are.
            Dunno why you'd want a tungsten ring either. There are much denser metals.
            Uranium, plutonium........

            BTW, hope retirement brings you joy and peace.

              Tungsten is actually slightly denser than uranium. Still, what's wrong with platinum?

                I just did a quick web search for "tungsten carbide ring." Allegedly, they use a tungsten carbide alloy that doesn't contain cobalt. At least some of them claim to.
                It sure wouldn't be my thing. I see no artistry in them, but I guess there is no accounting for taste.

                  Nuthin at all wrong with platinum. Even in today's market, it's still gotta be cheaper than plutonium.
                  Mind you, if it's a question of density, Pb at 82, Pt at 78?

                    A couple of my wife's friends had a pair made out of meteorite material. Whatever floats your boat, I guess.

                    If either partner is suspected of "getting around" you could make them out of brass. Even if they took it off the green stain would be a dead giveaway.

                      Hell, pretty soon the wedding ceremony will include a vet with a "chip" needle

                        A.) It's cheap. B.) It's tough as all get out and they're rough on jewelry C.) They're heavier than titanium, and thus they know when they've got it on and it hasn't slipped off.

                        So, I guess I'll tell them that Henny Youngman's not happy with their choice.

                          I machined mine out of 303. Held up pretty good, course 2.8 years later I don't need it anymore...

                            Uh, no.

                            Tungsten carbide wedding rings are very trendy these days.

                            Where did you get the idea that cobalt was toxic? Cobalt is an essential element in humans, as a constituent of vitamin B12.

                            http://www.epa.gov/ttnatw01/hlthef/cobalt.html

                            Human studies are inconclusive regarding inhalation exposure to cobalt and cancer, and the one available oral study did not report a correlation between cobalt in the drinking water and cancer deaths. EPA has not classified cobalt for carcinogenicity.
