Nordic gold
Nordic gold is a brass alloy made from 89% copper , 5% aluminum , 5% zinc and 1% tin ; so it does not contain gold . It has a density of approx. 7.01 kg / l and is not magnetizable .
This alloy is used to produce euro coins with the denominations of 10, 20 and 50 euro cents and was already in use as a coin alloy in some countries. It was originally developed for the Swedish 10 kroner coin, from which the name comes (Swedish: nordiskt guld ). Important design criteria met by Nordic gold at the time were:
- alloy gold color,
- little tendency to tarnish or discolour,
- good malleability for coinage,
- high durability and wear resistance,
- low allergy potential .
Since Nordic gold does not contain nickel , the risk of contact allergies is low.
