Hello everybody. Ive searched this question and get many that say its ok and some that say it is not good to use for audio circuits.My understanding is the skin effect is what most people are thinking of,but that is only a concern in high frequency.Audio is low frequency.What other reasons may be of concern? I have a lot of it and love to use it since its easy to solder,holds its shape when routing,and over time does not oxidize. Just looking for more opinions. Also, what would be the highest usable frequency if you were to use it in RF circuits?Im talking interconnects and such, not winding high Q coils or anything.
