I suppose you all know this, but the quotes around "silver" make me wonder.
There is actual silver metal, usually sold as sterling silver 92.5% silver 7.5% copper. The copper makes it a little stronger than just pure silver metal. This stuff works under a hammer like nothing else, you can do things with silver & a hammer that will not happen with copper or brass.
Then there is "German Silver", or "Nickel Silver". This is an alloy of copper, zinc, and nickel. It is whitish in color and works, very roughly, like brass. It became popular in the early 19th century for fake silver inlays on firearms.
I don't know which alloy is your inlay. I might, or might not - be able to tell by looking at it. You said it was corroded. I wonder, what color is that corrosion?
Acer's tutorial is fantastic.
