Is it nickel?

[Terry, NJ]

I was scratching around in my van and I found two old house keys. They look like nickel (dull silver with a yellowish cast) but are they some old alloy of nickel and something else? I want to use them as sacrificial anodes and try to plate off them. One says P.F. Corbin New Britain, Ct and they other has Yankey mfg Boston, Mass. is there some test I can with house hold stuff to tell? They have some fairly high quality die work but what good are they? Other stock I've used for anodes has had too much "alloyed" with it to produce a good solution. AmI just wishful thinking here?

Terry, NJ Quit trying to cheap out and get some nickle rod. It ain't that expensive that it will break the bank and if you do it right the first time it cost less than redoing it to fix the cheap job.

I'm always looking for new sources! If these keys are usable, I 'll use em'! However, May I say that while your source seemed promising at first I concluded that it is a rip off. How so? you may ask! Well I concluded that THE little (singular) piece of nickel that they're selling you is 5 mm, about .200 of an inch. Slightly more than 3/16 of an inch, it probably weighs slightly more than the shadow of the whole NY skyline. You can do much better at United Nuclear (Google) Bob has little nickel shares (1"X1"X 3/8") he is peddling at $5.00 a chunk.
