Nickel

My unusual 50p car boot find today is a bar of strange looking metal 8" x 1" x .5" thick. It was only when I looked at one end I could see it had been stamped "ROLLED NICKEL".

I have never come across this stuff before so the question is........what do model engineers do with rolled nickel?

Rik,

What colour is it?

I would hazard a guess that it's nickel plated, eg. " rolled gold".

Ady - The colour of the bar is odd. It is overall very light matt grey with a hint of green/blue and almost opalescent. Whoever had it before me had hacksawed of a small piece leaving a finish no different to stainless or mild steel. - Rik

Nickel is corrosion resistant, it sounds like the outside of your bar has tarnished, but the cut face is still fresh.

Don't know anything about it, but might it be an electrode for electoplating? Ian S C

Ian - the odd tarnishing on the surface of the bar might well have got there from it sitting in a bath of electrolyte. "Rolled Nickel" suggests to me that this is pure nickel and not a nickel alloy. So all in all I reckon you could well be correct with your "plating electrode" suggestion. Thanks for your nickel ode Ian >>

Rik...

Pure nickel is ferromagnetic and when tarnished does indeed have that weird colour that you describe.

Ian's probably right in thinking it's an electrode (anode iirc) for nickel plating.

Thanks to Malcom for perpetuating this thread, I feel well plated chaps!
