Nordic Gold

Nordic Gold (Swedish: nordiskt guld[1]) is the gold-coloured copper alloy from which many coins are made.

It is non-allergenic; its other advantages include antimycotic[6] and weak antimicrobial (especially after abrasion)[7] attributes, and resistance to tarnishing.

[8] Nordic Gold was developed by Mariann Sundberg while she worked for the Finnish metal company Outokumpu.

"[10] Compared to commercial copper metal, Nordic Gold has significantly smaller grains.

[11] The alloy's antimicrobial properties were studied extensively in 2014 because it showed promise for use in hospitals, to help prevent MRSA infections.
