I have a customer who has asked me to cast small hardware in
Nickel silver is really just nickel, I’m pretty sure. It’s not an
easy metal to cast, it’s hard to melt. I’ll bet you’ll hate it. Why
not try one of the bronze alloys like white bronze or caster’s
bronze? Rio Grande has a nice selection of non-precious casting
metals. Pewter is a breeze to cast, you can cast it directly into a
silicon rubber mold, but you’re not going to find it easy to have
plated, and of course, it’s pretty soft, but it’s pretty and if the
sections are thick it’s strong enough. Bronze will plate pretty
easily, but you’d be advised to have a specialist handle it for you.
It’ll probably need to have a copper flash, then a nickel coat, then
whatever you like after that. Silver might not be good choice if it’s
going to be handled a lot, since it’s going to have to be very thick
if it’s not going to wear off. Better with just the nickel plate.
