Thermal expansion of music wire
(OP)
Is the thermal contraction/expansion of music wire linear? If so at what temperatures does the linearity break down? Thanks.

Music wire is also used in its annealed stated for cutting foam but there are better choices if this is what you are doing. Foam cutting temperature should be less than 300 degree F.
I would guess it would be in the range of 7-10 millionth inch per degree F and fairly linear to around 550 degree F. You should be able to get much better numbers from the supplier.

Compression springs are usually specified with +/-10% tolerance on the force in a specified deflection.
There is an alloy C-SPAN (I think) that has a constant elastic modulus over a wide range of temperatures which is usually what bother designers of very accurate springs but not the expansion contraction of the wire.

Why do they call it music wire?

Tiny springs, I assume.
Sorry for the diversion.
