CU with nickel

I heard there is nickel plated copper , Is there also silver plated copper
& how does one tell them apart. I have encounter the nickel plated CU with Ice freezers.

many silver over copper items will actually say "silver plate over copper" right on them. I don't knink all of them will, but you can scratch them to find out.

I have been finding these 10 inch long wires from the electric company they are silver or nickel ? with CU - it has a orange tube that is easy to pull off leaving the wire and a flat nail head like end to the wire

This is a subject I'm not sure about at the moment.

I thought the silvery covered copper was 'Nickle coated' copper, then I found out its 'Tin coated' copper.

Tin & Copper mixed is Bronze. Should I be putting this metal in as 'Bronze'?

I'm getting most of this metal as the long thin tube thats connected to the fridge/freezer thermostat, only have a Kg but I want it to go to the right place.

kiwi, I'm amazed....a subject you aren't sure about. jk I've been amazed at your vast knowledge, but surprised that you would ask about putting coated wire in as an alloy. correct me if I'm wrong, but there's a big difference in my mind. I just googled tin coated copper and found a lot of info if anyone really wants to know. btw, if you have a small amt of tin coated it is easy to scrape the tin off with a blade.

Is the tin actually tin, as in the the element? Fairly expensive stuff if it is. Wonder if it would be worth it to reverse electroplate it in quantity if it is.

there is tin plated copper wire, nickle plated, silver plated....it's interesting to research.

Brass is an alloy of copper and zinc -
For me i never had an issue of the yards taking any CU wire with no casing Be it tin nickel or sliver coated - the reason i ask, is if it is silver that could have extra value i am not getting form someone who might do silver recovery as i see those type of individuals want any silver they can get to put into there chem. solutions . I need nitric acid for testing silver but even on ebay a bit costly
I would think if it was tin coated it should react to a magnet ever so slightly

Tin is non magnetic, this is the confusion some people have when they call their light mixed steel 'tin' Tin is a totally different metal with different properties and a much higher price.

I'd sure like to see a piece of this tin . For all i know it gets mixed with AL when i sell
I know what di-cast is , & i always wondered why tin bullion is so costly - well that must be why LIKE " 4 oz 99.9% TIN Bullion Bar is
$9.99 " so the thought that - nickel - tin - silver - over CU may have extra value ??
i still wonder
So what application is tin (non feris used for)

Those are fusible links I believe. I see them on the side of the road sometimes after storms roll through. I have a brand new one kicking around in one of my toolboxes somewhere.

Have you not seen people selling all sorts of crappy metal bullions for well over the price of the metal? Sure tin expensive compared to a lot of other metals but its still less than $1 an oz. Tin is used to make solder, pewter, bronze and to coat other metals to stop corrosion -like cans, giving the name 'tin cans'
