Personally I found soldering brass metal not very difficult. I mean here low-temperature soldering, not plunging.
So it may make sense to ask for use it as a pcb material. Especially if the board should be thick and stable.
I think "German silver" would be another material especially for model builders.

Thank you for your explanation!
