Silver plated aluminum???

[kdaddy]

The copper or brass cylinders are usually removable from the housing via a single torx screw in the center cavity of the cylinder.
I usually remove them and save till I get a couple of buckets full. I wish I could find somewhere that would pay a little extra for
the silver content but no luck so far. They are free to me so it's all good.

You might try some sodium hydroxide on a small piece of the aluminum.

I had some buss bars of plated aluminum cut into short pieces that when reacted for a time in lye the plate shed like a skin and still left most of the aluminum for the scrap bin.

hi!

those are aluminum with silver platings, you will notice the discolourations of silver platings, u can recover the silver by washing it with some 10% nitric over and over until all platings dissolved, salt it. :wink:

follow steve's silver chloride conversion on his website.

If they are copper or brass try steaming them with a 30% solution of water and nitric. i use a crock pot to heat the solution and a ice cream pail to hold the parts. i place a pail of ice on top to condence the steam. After a few hours i turn off the crock pot and let the parts dry for a day or two. dump out the parts and shake off the plating. It seems crazy but it works well if your patient. Best of luck!

Definitely appears to be silver tarnish or heated silver plating. I cant get anyone to pay extra for Ag covered Cu busbars so I doubt anyone will for this. Why the plating? Are they conducting over the box?
