IS there a simple test that can be done to distinguish between brass and phos bronze?   i have a part that may be phos bronze, but would like to know for sure.

RE: phos bronze id

It could be done with eddy current electrical conductivity measuring equipment. It could be done by density, if you have a jolly balance (used for rubber and plastic density determination). It could be done via SEM/EDS. But, I'm guessing that you don't have access to any of the above. You might try color comparison. Polish a small area of the part and compare to a known piece of brass and phosphor bronze, also polished. The brass will be more yellowish, the bronze more redish.

Thanks swall,

i dont even know what those pieces of equipment are  haha.

I have  comparied colour as you say.  Fairly confident it is a phos bronze part. Not critical to know for sure.
Wah hoping for a simple drop  certain acid on part and see change, but you never know untill you ask.
Thankyou.
