In modern society, the main use of gold is: 1). It is used as international reserves. This is determined by the gold currency product attributes. Due to the excellent characteristics of gold, the function of gold as currency in history, such as value scale, circulation means, storage methods, payment methods and world currencies. 2). Use as jewelry decoration. Gorgeous gold jewelry has always been a symbol of a person's social status and wealth. 3). Application in industry and science and technology. Because gold has a unique and good properties, it has extremely high corrosion stability; good conductivity and thermal conductivity. 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. The international gold prices soared sharply after 2015. The price of gold in New York's market went up all the way from $ 1,200 per ounce, and it has risen to $ 1,300 in less than a month. Statistics show that the price of gold futures in New York market has increased by 9.3 since 2015 %. The physical properties of extension
1, color: The steam emitted when gold is melted is green; its gold powder during the smelting process is usually brown; if it is cast it A thin piece, it can convey 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 4 million -foot thick and 100 square feet. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the strong flexibility and forgedness of gold. The color of gold is golden yellow, metal luster, difficult to break down. The hardness is 2-3, the pure gold is 19.3, 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. Reference information Source: Baidu Encyclopedia -Gold

Pucting information: Gold can also be used as solder, but not the main purpose. Ter welding or copper welding made of gold is usually used as a component of high -temperature hard welding or connecting gold jewelry. Golden Artists use independent welding interfaces to combine complex objects. Gold welds usually have three different hardness and high hardness welds are preferred, followed by lower hardness welds. Gold welds must be the same as the purity of connected items. Reference materials: Baidu Encyclopedia
Gold is increasingly used in the fields of traditional industries and modern high -tech industries. More and more electronic components such as electronic technology, communications technology, astronomical technology, chemical technology, and medical technology can be used. Raw materials. Of course, gold has financial attributes to be currency. (1) Gold as jewelry and utensils This is the earliest use of gold to make jewelry. Pure gold jewelry is small, high in value, convenient to carry, and has the function of preservation and decoration. It is an ideal gift and gift. It has always been loved by people. (2) Electronic industry Gold has the best mechanical processing performance, which can be pulled into a few microns with a diameter of a few microns. In addition, its conductivity is very good and antioxidant and corrosive It is widely used as electric contact materials, resistance materials, welding materials, temperature measurement materials and thick membrane slurry. (3) aerospace industry Gold is also used in the field of aerospace due to high temperature resistance and corrosion resistance. Applying to buildings can play a good role in preventing solar radiation and heat insulation). (4) Medicine Gold is widely used in medicine. my country ’s famous Chinese patent medicine -Tongrentang’ s “Niuhuang Antong Pills”, “Niuhuang Qingxin Pill”, “Niuhuang Blooding Pill”, "Dahuang Dan" and other gold foil are used or wrapped with gold foil. 5) Consumption In recent years, the consumption of gold foil in Japan and Southeast Asia has prevailed. Gold foil meals, gold foil wine, gold foil water, gold foil candy, and gold foil cakes have come out one after another. (6) Building decoration Gold can be used for the decoration of the building, playing the finishing touch. (7) Chemical industry In the chemical industry, the surface inert pure gold is distributed on the carrier material. For certain chemical reactions, it is active and can be used as a chemical catalyst. (8) glass plating and other manufacturing in recent years, glass gold -plated technology has matured. A gold film with a thickness of only about 0.13 microns on the glass can effectively reflect infrared rays. At the same time, it is also a kind of insulation medium, which does not affect the transparency of the glass at all. (9) Scientific research and new materials With the advancement of technology, the application prospects of gold are wider. In terms of scientific research, gold can be used to capture slow neutron. The radioactin of gold can study the diffusion process in metal and alloy. It can also study the role of chemical and physical adsorption, and determine the solubility of various compounds. Using golden trace atoms can also identify the authenticity of antiques without damage.
Spot gold is investment and financial management. Stock (also known as international spot gold and London gold) is a period of time, which means that it is delivered or delivered within a few days after the transaction. Spot gold is an international investment product. Each golden company establishes a trading platform. In the form of leverage ratio, it will conduct online trading and trading of online trading, and formed investment and wealth management projects. comparative items have no shorting mechanism for stocking. You can only use low buying and selling high -selling. It is profitable in the ups and downs. , Buy the day the day the day can be sold. The short -term index futures have a short -term mechanism, which can make profitability in two -way transactions, and there is a profit opportunity in the ups and downs. The T 0 trading system can open positions and liquidation on the day, and there are many trading opportunities. At the same time, it is necessary to rub the transaction, but there is a limit of the delivery period, and it must be delivered or liquidated on the date of delivery. The gold spot transactions have short -term mechanisms, which can make profitability in two -way transactions, and have profit opportunities in the rise and fall. The T 0 trading system can open positions, liquidation, and trading opportunities on that day. Without the restrictions of interchange, it can be held unlimited.
