Are all titanium split rings magnetic?

The place where the light don't shine
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?

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 wonder who first thought of this principle ....[emoji317]

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.

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.
.... Eureka ! :grin2:
