Ckozka, my material is pre-plated via hot dip galvanizing process. I have a copy of SMI Handbook of Spring Design. It says that a temperature range of 375 to 450F is suitable for music wire and your recommendations are fairly in line with this book. I have about 7pounds of parts to stress...
I am playing with a zinc coated music wire. I was told 500 deg for 1hour for heat treatment but that seems kinda long. Parts have very low mass and wire size is about 0.040". any other recommendations from your experience?
