Nickel Silver alloy for wheels?

Post by ConnRiver »

I'm going to get going with a diesel wheel project. I'm looking for nickel silver bar online but so far have not found which nickel silver alloy is commonly used in model railroading. Anyone have that information?

On OnlineMetals.com I'm looking at Nickel Silver Round 792. Thanks.

I don' t think I've ever seen a specific alloy or requirement for NS wheels, I think they started using it more for it's corrosion resistance compared to regular brass so I don't think it would really matter. If there is enough nickel content to call it nickel silver I'd guess it would work/
The only way to be 100% certain would be to talk to someone who makes wheels or has them made- I don't know if
Matt at Fox Valley Models or someone at Reboxx or Intermountain would be willing to spill any trade secrets?

Thanks, Al, good ideas. Well, I think I'll order a one-foot long x .375" dia. bar ($15) to play with. And, I can pursue the alloy question down the line if necessary.

Maybe there's a way to test conductivity? I'll google that, see what comes up.

Ha! Just found instructions for testing conductivity. I can compare the alloy I'm purchasing against existing model railroad NS wheels.

The critical issue is NOT conductivity... it is machine-ability.
On the recommendation of many long-time modeler machinists, I purchased a 3/4in bar of LedLoy...
also known as ANSI 12l14 steel.

The best nickel silver for a lathe is CuNi7Zn39Pb3Mn2 (CW400J). The second best would be CuNi12Zn30Pb1 (CW406J). Less than 25% zinc (Zn) is poorly millable, has a less machinability.
