Main gear question

[Chuck750ss]

Are there any non destructive tests one could do to determine the composition of non magnetic main gears? Brass/bronze is obvious. I can tell stainless by the weight. Just curious.

Any scientists around?  Could you work it out by S.G. of the part?

sure, if it's an element -- not so useful w/ an alloy

Did you check the second link?  It suggests how you can work out an alloy.

presumes known percentage of each element in a proprietary alloy or pot metal -- how would you know?
