Not been on the forum long and finding out there's more money to be made than i realized. relay's were not a component i thought of selling, they must be worth doing i guess, they are if i am correct made of copper and maybe silver and gold, apart from taking off the plastic is there anymore to be done? or do i sell them whole.

There are many diffrent types of relays. The kind i get come from air conditioning equipment. They all have a copper coil, and contacts.
The contacts can be many diffrent alloys, but the main ones I find are silver/cadmium alloy. Some are gold plated silver alloy.
The time it takes to break them down by hand may not be worth it to most, But i listen to audio books while doing it and the time seems to fly by.

As a reminder to those that recover the contacts from relays: CADMIUM OXIDE IS DANGEROUS STUFF! (look up a MSDS) Its' wispy white smoke coats everything around it as it vapourizes and spreads it's danger if handled incorrectly. Proper PPE and clean-up procedures are vital in your efforts for everyone around you!
The alloys used vary widely depending on the intended use of the relay. Looking up the composition on sites that have manufacturers spec sheets is time-consuming and counter-productive if you have plenty of one-off pieces, leading many to sweat the contact points off in bunches, regardless of the composition. If you do this, assume every one of them is Cadmium oxide and treat it accordingly! A little bit of precious metal is WAY LESS precious than your, or your loved ones' health! Be safe.
