[Source] Spring Wire?

Does anyone know where I can purchase some 0.1 - 0.3 mm gauge
spring wire that will not lose its spring after heating?

Hello Marcus:

    Does anyone know where I can purchase some  0.1 - 0.3 mm gauge
spring wire that will not lose its spring after heating? 

To my knowledge, there is no steel wire that will not loose its
spring when heated. I have recently heard about a platinum alloy wire
that is supposed to put up with heating and remain springy. I know
that R-Findings is using it in some platinum findings. I hope this
helps you. http://www.rfindings.com/rproducts.html 3300 Monroe Avenue
