Recycling industrial machinery. New to forum.

The part in the picture is 3" wide, 7-1/2" long and would average around 1/2" thick. It weighs 3.28 pounds. I would estimate that I have over 300 pounds in castings on one machine. I am leaning toward a copper/nickel due to the color in the test.

If it dissolved in nitric and turned blue/green it is some form of Cu alloy. Nitric acid will not attack Al. The pic looks like a white brass of some sort. this is similar to silver plated silverware. You need an XRF reading

Do you come across large electrical contacts?

I remove silver contacts from starters if they are old or burnt. The rest I sell complete. I use to sell the contacts on ebay, but lately have been saving the silver for retirement.

I am going to take a sample to a yard and they are going to shoot it.

well if you need any help with the contacts let me know. I can convert them to large poured bars or small silver rounds.

Any questions you can contact me through my website.

welcome to the forum.
