anyone know what this stuff is actually made of? i know the contact points on the end are silver... but i am curious what the core of the wire is made from. google cant help me and this is the closest thread to answering what its made of.

i scrap so many printers that i just trim the ends for silver, but there might be silver throughout like a keyboard cellophane

when my gold/silver/platinum test kit shows up in the mail, i'm going to test it for sure, but i thought i'd raise the question first.
any refiners have an idea?
