My suggestion would be to look for silicon brass or i prefer silicon bronze wire. Those have a beautiful aged look to them.
The prob is they are mostly plastic since the materials like to migrate. Thus they are very hard to drive due to it being mostly grains of metal in a plastic.
Real Bronze wire is really hard to get since it has to be ultra pure and then have ultra pure aluminum burned into it carefully to avoid vaporizing the bronze. If it is impure, the aluminum alloy process will lock the impurities in place.
The aluminum must also be very pure and specific energetic match or it will either not hold the quite energetic bronze or will gather other materials readily in an almost infinite manner to create ubiquity(What) metal? (AKA _tah)
Tungsten/Titanium alloys are even harder as they take a very very long time of heating and cooling cycles to alloy. Western Titanium/Tungsten true alloys are virtually non existant but strangely do exist in human form...daumn...prob a baddd idea
Bronze and brass can be used but have to be carefully shaped to retain their contents with specific self resonant shapes. If they have to be moved far from thair source of mining, they have to be plated with Tungsten/Titanium or cored with aluminum otherwise they will fade to what we generally consider (gold) (aka colored lead) (funny aluminum).
Silver, Gold, and copper are another game. Almost impossible to not burn to (funny aluminum) (aka energetic lead). Exotic copper such as Tellurium Copper from the Tellurium mine on I-70 between Denver and Vail can have small amounts of energy applied to it. Tellurium Silver has been reported to destroy miners and Tellurium Gold will really mess you up. They all age to the relatively safe Tellurium Copper. In fact the mine still spits out the stuff to a big cauldron.
Sylvanite crystals are pretty much the scariest thing one can witness. If they are really silver has yet to be proven...ala schrodiners kat. Strangely, they like to stay in place...Mica strangely looks silver but behaves like (funny lead) Thank the Founding Fathers? More like the Native American(s)...whatevs.
If anyone still wonders where Mount Holy Cross really is, figure it out...im not telling. Bad serpentine belt eh? I thought Everest/K2 looked difficult...mere weaklings. Just make a sphere, haha, and be sure to use some glue. (hint, negative space, another hint dont go out of bounds from Wildwood or Inner Mongolia, esp Inner Mongolia, esp Inner Mongolia)
