Pure Silver Wire

@roxy54 

I was suggesting solid core large diameter. Have heard about silver strand speaker wire but it's more like the solid core like you find in house 12/2 electrical wiring style. It's not all that difficult to find someone that draws wire and silver ingot is not that expensive 

This is actually something I wouldn’t mind trying.

Silver bar is 99.9%+ pure. Sounds pretty high. So much so that I feel there is no degradation due to alloys. Grain structure ok. I do understand that metrology is something have experience with as a manufacturing engineer. A nice annealing will align back the grain structure and allow malleability again by taking out internal stresses.

The elastomer covering is a pretty easy process. The purity is actually makes things a bit tougher as it would have to be handled with care. If things don’t work out I can strip the wires and sell as scrap weight costing me only the wire drawing cost with elastomer. It’s 13oz plus grip (grip is the wasted sections needed to hold the material and work with it through the dies) to make 4pcs of 10ga x 6ft long each
