Non magnetic spring metal
Non magnetic spring metal
(OP)
Hi there,
My metallurgy knowledge is not so great.
Does anybody know if there is a spring material with the following properties:
1. Non magnetic
2. Not extremely expensive
I am looking at the possibility of making a spring similar to a wind up clock with no magnetic effect.
I know of people that have just used 316 stainless, but that is only for limited movement and vulnerable to fatigue
Thankyou
Gavin

RE: Non magnetic spring metal
1) Non-Magnetic -- thus you cannot use any Fe-Based Matl'
2) Inexpensive -- So the Ni based alloys are out, so are any other exotic alloys.
3) Good Fatigue life -- So all the austenitic alloys are out (they will turn magnetic when engouh CW is present to make them springy)
Otherwise I would reccommend Inconel x750

For good strength you will need to spend some money. High Ni alloys are the way to go. You don't need a fancy age hardening alloy.
I will hunt for my spring wire handbook.
