Beryllium Copper Specification

[tedg]

Can anyone tell me the composition and properties of a beryllium copper alloy identified as NSB4?

Is this a foreign standard? Where can we buy the alloy?
Is there an equivalent North American alloy?

Any information would be much appreciated.

I would suggest contacting Brush-Wellman, a manufacturer of Be containing alloys. They have a website, but I dont know the name of it. Im sure they will have the information you need.
