gold relay contacts

[azgard]

i found a few small relays out of a piece of lab equipment. i snipped off all the gold looking contact points in them melted them down to a 1g button. tested out at 12k gold. i was just wondering if alot of relays have any good gold content in them. i can get a ton of them i see alot are silver colored but a bunch of them are defenly gold looking but i would have to cut one up to see if its plated or solid.

They are mostly gold plated. You probably got some solid ones and some plated. How did you test that your button?

The relay that I have are the DM3 series. According to the data sheet, which makes contact Ag-GS. I buy that the GS means gold and silver. I'll even buy the alloy is . I would prefer a quote source as I myself, have not been able to achieve something on my own.

Hallowen, It might be beneficial to have a metal expert teach you for a couple days. The chemicals are dangerous. I believe it would be cost effective as well, since you have 4 tons

I must have missed something, where does it state there are 4 tons of these?

I see on another topic it is posted about having access to over 4 ton of computer circuit boards, is that what you are referring to?

i acid tested it. rubbed it on abrasive stone. the 14k dissolved it slowly the 10k didnt touch it so appears to be right between 10 and 14. i got like 6 or 7 more similar but bigger relays with more contacts ill pop allthem off once i get the chance see how much there is on them.

It is impossible to say, your pictures are out of focus (pictures can by the way not say anything regarding the karat of Gold)
