Nordic gold
Nordic gold is the gold-coloured copper alloy from which the middle three denominations of euro coins, 50 cent, 20 cent, and 10 cent coins are made. It has also been in use for a number of years in other countries, most notably in the Swedish 10-krona coin for which it was originally developed[1] (hence the Swedish name: nordiskt guld).[2] Its composition is 89% copper, 5% aluminium, 5% zinc, and 1% tin.[3]
Despite its name, it contains no gold and its colour and weight are quite unlike pure gold. It is non-allergenic; its other advantages include antimycotic[4] and weak antimicrobial (especially after abrasion)[5] attributes, and resistance to tarnishing. The alloy and its tradename are the intellectual property of the global metals and manufacturing group, Luvata (formerly Outokumpu Copper Products).[citation needed]
