Nordic Gold

I'm planning on making a ring out of a coin.
I'll use Euro coins.
1, 2 e 5 Eurocent coins are made of copper covered steel and are too small, so I think they won't be a good choice.
1 and 2 Euro coins are the right size, but it seems that they are made of alloys containing nickel, that may cause allergy.
So I think I'll use a 50 Eurocent coin, that is made of Nordic Gold, an alloy (89% copper, 5% aluminium, 5% zinc, and 1% tin).

Has anyone ever made a ring out of Nordic Gold?
Did it cause allergy or stain your finger?   Did it tarnish?
Is it malleable?

Thanks

Interesting; I'd never heard of this alloy, probably because we don't use coins made from it in the UK.  There's an interesting article about the development and properties of Nordic gold HERE.  According to the article, it is malleable and non-staining as well as non-allergenic, durable and non-tarnishing.  Sounds ideal.
Wonder how it works ? Copper alloys tend to work harden, and need annealing periodically.

I just made a ring out of a 50 cent euro coin. It worked out really well - it took about four hours of tapping with a small hammer to widen the edge to about a 1/4 inch. I drilled out the middle and used a file to widen to leave only the stars on the inside edge.

It looks good.

Thanks for sharing.

Did you wear it?

Thanks, I can't quite fit it on my pinkie finger but it does fit my kids and wife. I made it for my son because he loves The Lord Of The Rings.

For the three middle denominations, 10, 20 and 50 Euro cents, a nickel free metal sort with a golden colour was sought after. The choice finally fell on a relatively new material: Nordic Gold.

From http://www.fleur-de-coin.com/eurocoins/specifications

"Nordic Gold was originally developed more than 10 years ago for the Swedish Mint and is today being used for the Swedish 10 Crown coin. It is a brass alloy, made up from more than 89% of copper, 5% aluminium and 1% zinc.

By adding aluminium the material gets its pretty golden shine. For normal daily use the shine remains and the coins do not become mat. In contrast to brass or bronze Nordic Gold is difficult to produce, meaning that the risk of counterfeit is reduced.

Moreover there is great skill and technical knowledge required to make Nordic Gold into a coin. Because of the difficult processability the alloy is not used for industrial applications."

No idea how it might work - I expect it to be quite hard and in metal content worth less than 50 Euro.

You can buy sheet silver relatively cheaply if you would like to use a precious metal.

if you want to start from a disc.
You're going to have to vacuum melt it I bet, with the aluminium content.
