It has fine, insulated, solid-copper wires. You can easily bend them. However, if you repeatedly bend them, the copper will
fatigue and break.
Does that answer the question?

Wow Dave, all this time and I finally caught you in a slip-up, haha! ;D
Never thought I'd see the day, you seem to know everything else.
So I'll relish that opportunity to actually teach something to one of our resident experts.
That wouldn't be fatigue, that would be work-hardening. Fatigue is when the weakening/breaking of a metal is from excess repetitions of elastic deformation. This is the kind of deformations that comes back, a la a spring. If you are only elastically deforming something, it goes back to the original size and shape on its own when you remove the applied force, it does not permanently deform.
Bending a copper wire changes the shape of the metal, so that's plastic deformation: the deformation stays when you remove the force. Doing this over and over does make the metal more brittle and easier to break, but due to work hardening, not fatigue.
And that's your materials science lesson of the day. [smiley=thumbsup.gif]
Cut into 9cm strips, staying in very nicely. Took a bit of force to get them in, but that clearly will pay back with long-term grip. Didn't use any tools.
