@starseeker@snouts.online copper clad aluminum maybe...? But would aluminum dissolve in nitric acid? probably

@starseeker@snouts.online common types of electrical wire are solid copper, solid aluminum, stranded copper or aluminum, stranded aluminum around a steel core for structural strength, tin plated copper, and in extremely specialized applications, silver plated copper or solid/stranded silver. Gold is also used for bond wires internal to ICs, but you don't often see it otherwise except for gold-plated connectors

@starseeker@snouts.online oh and also nichrome wire is really common because it's good for making wire-wound resistors and heating elements

@Motodrachen @starseeker@snouts.online Do they solder better with lead-free solder by any chance? Seems like solder that contains some amount of silver would bond more easily to silver wires.

Actually apparently ENIS is becoming more popular a board finish and I wonder if that would be more suited to silver solder....

@Motodrachen @starseeker@snouts.online er, ENIS = electroless nickel immersion silver, basically your board gets plated with nickel and then silver, as opposed to the common cheap HASL where it just gets dipped in solder and then Hot-Air Surface Leveled, or ENIG which is the same as ENIS but with gold instead of silver
