Gold and Its Properties

Gold has lost little of its power of attraction over the millennia. It is the most popular metal for jewelry in addition to silver. Some reasons why gold is also still popular nowadays, are its special characteristics.

Gold impresses with its pure shine and its softness. It is immune to oxidation and corrosion – in contrast to silver, which reacts with the sulfur-containing components of the air and produces a black covering of silver sulfite. The corrosion resistance of gold means that it is used in dentistry as filling material. Gold fillings are not attacked by acids.

Gold is also crisis – and inflation-secure. While it was used thousands of years in the form of coins as currency, it today serves as an investment and is stored by many central banks in the world in the form of investment gold as a currency reserve.

Gold is also a good conductor of heat and electricity, so including switch contacts and electronic connectors are gold-plated.Gold and Its Properties 1

The purity of gold was previously measured in carats (kt), with 24 carat pure gold, i.e. gold. Now you gone over to Pro Mille information. A piece of metal with 1000 shares of weight typically contain 333, 585 or 750 parts pure gold, the rest consists of other precious metals, such as silver, Palladium, Platinum, rhodium, Iridium. Pure gold is too soft, that it could be processed to jewelry, so it is mixed with other metals. This process is called “Dissolution”.

Depending on the culture, there are certain preferences on gold alloys. In the Middle East full yellow gold jewelry is appreciated with gold shares between 833 and 1000 ‰, while in the Americas, an alloy of 585% is typical. White

Gold is produced for example by the addition of Palladium, red gold by the addition of copper.

The Olympic gold medals were incidentally, last in 1912 to one hundred percent gold. As a result of the price rise of gold, the medals are today made from silver and are just gold-plated, coated with a thin layer of gold. A medal contains according to the Olympic Committee just six grams of gold.
