High Strength Wire
High Strength Wire
(OP)
Help!! I am trying to wrap .022" high strength music wire around a 2" diam. cylinder without the wire taking a permanent set when unwrapped. I am currently using a zinc coated music wire with the tensile strength of 365ksi, but it is still taking a slight set. I am looking for something stronger or a diferent material that will spring back straight. The material has to be electrically conductive and has to be .020-.026" in diameter. Please let me know if anyone has any ideas!!

My engineering is rusty for the math, but you need to calculate the bending stress in the wire. Then you need to find a metal with the elastic limit above that bending stress. Since you are not breaking the wire, the uts is not the issue. When you exceed the elastic limit, the part takes a perminant set.

You either need a bigger drum or a thinner wire or a different material.
Carbon fibre springs to mind.
