Reply to "Repairing Broken Delrin Type Plastic Truck"

I stand corrected, it is (slightly) magnetic. (thanks)

I happen to have some JBW 1/4" thick around. The strongest magnets stick, weak ones like in plastic alphabet letters fall right off.

Titanium is mildly magnetic and has very low lenz ability, but it's there I guess. I had tried using it long ago on wheels, and they stopped conducting to the axle, I got no ohm reading either. I bet you some real good test equipment to read what's going on. I don't know how to guess on "dioxide", but I'm supposed to see "End Game" with a good chemist and saftey engineer tommorow, hopefully I remember to ask what he knows.

For some contrast, I had unbreakable titanium alloy eyeglass frames I know were not magnetic enough to be be held up by a large electromagnet (junkyard crane)

Fun: You could bend the metal temples wrapping the length around your finger and they'd spring back into shape. Ball the whole glass frame in your fist and they spring return back to shape.
