GO Moderator United States 6563 Posts	Posted 11/29/2007 12:47 am quote: Nordic gold is the 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-crown coin. Its composition is 89% copper, 5% aluminum, 5% zinc, and 1% tin. It contains no gold — this is unlikely to cause many misleading trade descriptions since its color and weight are quite unlike real gold. It contains too much zinc to be a form of aluminum bronze. I learned something new today and figured I'd enlighten someone else Report this Post to the Staff

halfabustisbetter Pillar of the Community United States 1984 Posts	Posted 11/29/2007 10:15 am Not only do we have to have a new name for every type of alloy, we usually have to have more than one, depending on the country/industry in which it will be used, and any slang/colloquial terms that will be the 'unofficial' names, etc. Report this Post to the Staff
Topher Pillar of the Community Canada 965 Posts	Posted 11/29/2007 2:25 pm I play brass instruments (trombone, tuba, etc.) and they have three alloys. 85/15 is red-brass, 80-20 is rose-brass (uncommon), and 70-30 is yellow brass. They all refer to the colour of the brass. (which is oblivious to me since I'm colourblind). Fancy names like Nordic Gold, Aureate Bronze, etc, are just a fancy way of saying "cheap coloured alloy".

chrisild Pillar of the Community Germany 1238 Posts	Posted 12/02/2007 3:23 pm The alloy called Nordic Gold was developed by Outokumpu. http://www.outokumpu.com/ Now you may say "brass is brass", but according to the company this mix minimizes "discoloration" (due to contact with sweat, leather, etc.), has a specific conductivity (16% IACS), does not wear the dies much, and is quite durable. And no, the US "Golden Dollar" does not contain any gold either. So what. Christian Report this Post to the Staff
