I'm looking for a very very thin wire that does not bend easily. Which kind of material should I look for? The thinnest the wire the better but copper can be found in a very thin format (0.01mm) but it bends with very few force applied to it.

What is the least ductile and thinnest wire material I can buy?

Thanks in advance

  • $\begingroup$ Less ductile than what? There are tables of values so all you need to do is look. $\endgroup$ – Solar Mike Mar 18 '20 at 5:48
  • $\begingroup$ The least ductile and I mentioned wired material meaning a material that is already being produced and can be purchased. I have looked around before asking but haven't find an answer $\endgroup$ – user1618465 Mar 18 '20 at 5:58
  • $\begingroup$ Here there is a list of multiple types of wire fsgsbxg.com/Eng_Wire which one is the less ductile of them for the thinnest diameter one? $\endgroup$ – user1618465 Mar 18 '20 at 6:11

    $\begingroup$ Do you mean wire with the highest stiffness ( modulus of elasticity?). $\endgroup$ – blacksmith37 Mar 18 '20 at 14:44
  • $\begingroup$ @blacksmith37 yes that's what I'm looking for. Thanks $\endgroup$ – user1618465 Mar 18 '20 at 18:08

For microscopic electrical probe pins, gold-plated tungsten is used because its stiffness modulus is large- which provides best resistance against buckling under compressive stress.

  • $\begingroup$ Or you can do the reverse: take fine gold wire and plate it with a stiff metal like chromium. $\endgroup$ – William Hird Mar 19 '20 at 16:15
  • $\begingroup$ Tungsten is the stiffest metal available. If a length of 7 in. is useful . look up TIG welding electrodes , as I remember they are cold worked . About your only choice unless you work for NASA. $\endgroup$ – blacksmith37 Mar 19 '20 at 19:59
  • $\begingroup$ Thank you so much guys! $\endgroup$ – user1618465 Mar 20 '20 at 1:33
