    gold (GOLD) is a single quality of chemical element (AU), which is soft, golden, anti -corrosion, corrosion resistance Precious metal. Gold is one of the rare, precious and extremely valued metals. Internationally, 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.
    The chemical symbols of gold are AU, and the English code in finance is XAU or GOLD. The name of the AU comes from a story of Aurora, a goddess of dawn in Roman mythology, means shining dawn.
    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 meters 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.
    The color of gold is golden yellow, metal luster, difficult to break down. The density is 19.3g/cm3, and the melting point is 1064.4 ° C; it has good ductility and can be pressed into thin foil. It has extremely high heat transfer and conductivity. The resistance of pure gold is 2.4P. Pure gold has good anti -chemical corrosion and is the best electroplating material.
    Gold, as a precious metal, has good physical characteristics. "Real Gold is not afraid of fire" is that the chemical stability of gold is very high. It is not easy to chemically react with other materials. You don't have to worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. The density is strong and the feel is heavy.
    The toughness and ductility, good guidance. Pure gold has gorgeous yellow, but after incorporating other metals, the color changes greatly. For example, gold and copper alloy are dark red, and the silver alloy is light yellow or gray -white.
