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 (hence the Swedish name: ''nordiskt guld'').〔(【引用サイトリンク】 url= http://www.predecimal.com/euroarticle.htm )〕 Its composition is 89% copper, 5% aluminium, 5% zinc, and 1% tin.〔(【引用サイトリンク】 url= http://gizmology.net/metals.htm )〕
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 and weak antimicrobial (especially after abrasion)〔 〕 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).
