Nickel-Silver and Copper-Zinc-Copper

[Rob Thorpe]

I'm currently looking at some materials for conducting springs.

Several materials are useful for things like including Phosphor bronze
and stainless steel. Also, some people have mentioned Nickel-silver
and Copper-Zinc-Copper.

There seems to be some confusion surrounding these materials. Is it
true that copper-zinc-copper and nickel-silver are both misnomers for
the same material?

If not, does anyone know what the differences are in terms of their
properties?

What are they actually made of?
