Nickel Silver, just like Gibson uses! Whatever that means.
These are plated nickel silver AKA "German silver". There is no silver in the alloy at all. It is actually mostly copper (60%), with just about equal parts of nickel & zinc, added. Unlike brass or copper, nickel silver stays cleaner, electrically, so it makes it a very good material for electroplating. It also shields EMI & RFI fairly well too. The high copper content makes it take electroplating really well too. These are die stamped, die cut & die punched, then plated with nickel, chrome, black chrome, gold, etc. I don't think the material selection holds any special "tone magic mojo", as Gibson claims, but is does make for easier & less expensive manufacturing. It also holds plating quite well too. Cast parts are notoriously hard to electroplate. Nickel silver is notoriously easy to electroplate. It also does not oxidize fast, so it is THE material of choice for model train track rails. These are well made, well priced & vintage correct. They fit vintage sized bobbin assemblies & solder up very easily. All in all, an exceptionally good product!
