    Default Are all titanium split rings magnetic?

    2-3 years I bought a bunch of Titanium split rings


    The sizes are 15mm, 25mm and 35mm


    They are advertised as Titanium split rings and they are priced accordingly,
    i.e from $2-3 for the 15mm and $5-6 for the 35mm


    Today out of curiosity, I took a neodymium magnet and go over them
    and they are attracted slightly(not very hard unlike those normal split rings)


    So I am wondering, is this normal since the split rings are titanium alloy(mixture of aluminium and vanadium)


    Or I am duped into paying titanium prices for these not really titanium split rings?

    Not all steel is magnetic ....

    Can you check the density ?
    ... is the archimedes peak

    Thanks for replying

    But how to check?

    The split rings are so small and light

    If you have a known reference ring (of steel and/or titanium) of the exact same size and shape (ie, same volume), then comparing the weight (or mass) will reflect the difference in density.

    Or, you can calculate density directly, from a measurement of mass and volume.

    Or, you can use comparative displacement of water, if you have a reference item of known mass (weight) and composition, and the same exact mass of these ring(s) .

    I own both an old-school Berkeley Point and a more recent Fenix Outfitters Rainbow split ring in titanium; neither react to a neodymium magnet in the slightest.

    Can't vouch for the accuracy of this website, but one comment to this answered question does reveal what CPF moderator archimedes was wondering about

    What an amazing human from so long ago...

    A couple of years ago a member reported titanium Nitecore flashlight clips that would fit onto the ZebraLight SC62 series. I bought the long and short clips. They work fine but one is magnetic. The titanium split rings I have purchased have all been non-magnetic, however.
