Title: Main gear question
Post by: Chuck750ss on February 12, 2018, 01:05:07 AM
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?

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?
