Or "silver-plated copper wire". Aviation, sea vessels, military, etc use a lot of silver plated copper for high temp applications. An example of military silver plated wiring would be M22759/11-10-9. The 10 is the guage, 9 wld be color, and /11 signifies silver amongst other things. M22759 is the spec & covers many types of wire both silver & tin plated. You won't see silver in any applications where there is direct contact with salt water as silver does not handle salt well.
