have long circulated in the network stories about supposedly fake gold bars with a core of tungsten. What then about it? First, is undoubtedly the set that specific weight of tungsten is almost exactly identical to 19:25 g / cm ³ with the specific weight of gold of 19:33 g / cm ³. Second, such a fake gold can neither by traditional science "Archimedes-water test" or by consuming modern test technology such as "X-ray fluorescence spectrometer . Notice Now, however, there are two relatively safe methods to determine whether it is real gold bars or not. Option 1 would be the sound test by hitting the gold bars and measures the speed with which the sound propagates in the metal. As the sound propagates much slower in gold than in the brittle tungsten, would have a real gold bar can produce a much deeper tone than a tungsten bars. What would be in direct comparison with the human ear to distinguish still good. Without reference should be analyzed by a computer program which metal is to be assigned which oscillation. Second, you can simply drill into the gold bullion and examine the chips. The latter made the Chinese after they exchanged a delivery American dollars and gold to own Treasuries.
Hong Kong - In October 2009, the Chinese delivery gold bars from the U.S.. Gold is the preferred means of payment, to offset the trade balance between China and the U.S.. Particularly in times when even Alan Greenspan admitting that the Chinese trillions in their green itch - that is to the U.S. dollar and government bonds - no one will be able to ingratiate. Now the Chinese are not exactly fallen on my head and ordered the Chinese government to the audit. It was about the purity and weight of these, coming from Fort Knox, 400 ounces of fine gold bullion. For this purpose, with a Drill 4 holes in each thin the tested bars drilled. What is difficult as strange anließ. The reason was soon found. In the analysis of drill cuttings was found that the bars not made of soft gold, but brittle tungsten (English Tungsten) passed. Of gold was only a thin layer that was applied to the bars around. This delivery to China 5600-5700 were the 400-ounce bar of tungsten. So to suggest as 65 metric tons of tungsten have been delivered as gold. Not a bad business at a price of 81 cents tungsten ounces!
Whether the Americans the gold forgery operate more aware because there is no gold in Fort Knox, "or whether they themselves have been linked, and the gold forgeries which have been turned on you, just wanted to push it further is unclear. But how stupid must one be key to its trading partners China foist those things? How have the U.S. boys certainly what they delivered as China was the clever and not determined, because the Chinese have known a long memory. The trend of China's men now at any rate away from the dollar and the U.S. and toward Europe and the euro. Also, the Middle Kingdom decoupled the yuan from the dollar which simply shows a drop in confidence towards the Chinese Americans. According to U.S. financial crisis, toxic U.S. securities, and now toxic gold from the U.S. that's not a miracle, I would which also do not believe everything! How far the fake gold scandal is to be determined because of lack of sources has not, however, investors in coins (1 / 10 - 1 ounce) as of small bars (0.5 grams - 1 oz) have to make probably less worried as such forgeries well too expensive in relation to 'small' coin and small bar value. It would be interesting to know in any case, the source of the gold-counterfeiting, because tungsten melts at 3400 degrees. In a backyard workshop you do not do something for sure!
Kind regards
