I did a job a few months ago and I had to remove some radio equipment, I had thought of trying to resell it as is, but then found out that the frequencies were no longer able to be used. Long story short, I removed the valuable parts for ebay, then I began disassembly. I am now waist deep in a bunch of things that I have never seen before and would like advice about what to do.
There are large amounts of cast aluminum that appear to be silver plated, it actually looks like they were copper plated first, then aluminum plated afterwards. Should I be trying to find a buyer for this or is it something that has no real additional value due to the effort to remove it?
Second I found circuit boards that look like they are silver as well. I have never seen any like them, but I am a total amateur at this. There are also boards that feel like they are ceramic that have a nice copper backside.
Third I have lots of copper that has silver solder on it, what should I do?
I also think I have found some gold plated pins, but have not figured out how to check them. I am posting a bunch of pictures to show what I am messing with.
1) Silver Plated?
2) After grinding you can see there is a copper plated layer as well.
