nickel silver sheet stock?

[nachoman]

Does anyone know of a common source for nickel silver sheet or bar stock? I want to use some on some electronics projects, and was hoping to avoid having to order large quantities of the stuff. I had a similar question on where to get phosphor bronze, and someone on this forum pointed me to common weather stripping- a great suggestion. I was hoping for a similar good idea on what common items are made from nickel silver that I could find at the local hardware store. I was looking for dimensions about 1/4" wide and 1/16" thick. I want to use it for touch switches, and worry that regular brass would oxidize over time and become unreliable.
