I am trying to get my hands on some Pin Wire -the wire used to make
pins for sewing and sheets of paper (also used in the medical
industry). My local suppliers don't know it by that name -all they
seem to have is softer Stainless Steel and when you think how stiff
those little pins are it just doesn't compare. Any compositional
specs. would be greatly appreciated.
You might try guitar strings (Plain, not wound). These are polished and
will be about 28" - 30" long. They're available from about .009" thru .016"
diameter. Several online sellers will sell you individual strings of a
given size so you don't have to buy a complete set. One such seller is

However, most shiny guitar strings are nickel plated, and that
oxidizes (maybe just wears off) pretty quickly when handled
extensively (as on my guitars). Seems like pins are chrome plated,
though I don't have one in front of me. (I seem to remember the chrome
flaking off when you bend sharply.) Also, even the thick guitar string
stuff is still pretty pliant compared to a pin.
What seems more up your alley is the wire used in spinnerbaits
(fishing lures). It's pretty stiff stainless, I think, and TNBass or
Bob Rickard (custom lure makers) might be able to help you out (on
rec.outdoors.fishing.bass) with a lead on a supplier.
You were looking for the stuff in a sewing pin, not a needle, right?
(Needles are very stiff and very brittle compared to pins.)
Need to be careful of terminology here. Needles may be more
resistant to permanent bending than pins, but assuming both
are made from some flavor of steel and of similar
dimensions, are not going to be noticeably stiffer.
Thanks John and Jamie,
I bought some guitar sting and although having a great finish and some
good strength it is softer than the dull piano wire. Am off to the
fishing shop now to look into that spinner wire.
Jamie, yes, I am looking for the stuff used in sewing pins although
the one I have must just be highly polished something because there is
no chrome flaking off on extreme bending -as you say sewing needles
just snap under strain.
Thanks again, I will report back the findings.
Spring wire is available in stainless steel. Tensile
strength and elastic modulus (stiffness) are slightly lower
than for music wire. The stainless wire has a bright
