Gold usually rises, and gold is precious metal, and prices have been rising slowly. Gold (GOLD) is a single -quality form of chemical element gold (AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and extremely valued metals. The international gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments. physical properties 1, color: The steam emitted when gold is melted is yellow -green; its gold powder is usually brown during the smelting process; if it is cast into a thin piece It can also transmit green light. 2, ductility: is extremely strong. 1 ounce of gold can be pulled into 50 miles long, and its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal. 3, forgedness: INO. It can cause extremely thin and easy to roll up. 1 ounce of gold can be hammered to 1 foot thick and 100 square feet with a large area of 4 million. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the flexibility and forgedness of gold.
