Bank gold can be divided into paper gold, gold currency funds, gold futures, physical gold and other investment methods. When purchasing, everyone must understand the differences, trading mechanisms and transaction procedures of different investment methods. fees, risk levels, etc. Take the bank's purchase of physical gold as an example. Investment gold bars are more suitable for investment than commemorative gold bars and should not be traded frequently.

Introduction to gold;

1. (Gold) is the elemental form of the chemical element gold (Au). It is a soft, golden, corrosion-resistant precious metal. Gold is one of the rarer, more precious and highly valued metals. Internationally, gold is generally measured in ounces. In ancient China, "liang" was used as the unit of gold. It is a very important metal. It is not only a special currency used for reserves and investments, but also an important material in the jewelry industry, electronics industry, modern communications, aerospace and aviation industries and other sectors. The chemical symbol of gold is Au, and its financial English code is XAU or GOLD. The name Au comes from a story about Aurora, the goddess of dawn in Roman mythology, which means shining dawn. As of October 12, 2021, the price of gold is US$1,760 per ounce.

2. Before the 19th century, the level of gold productivity in human society was very low. Some studies believe that in the thousands of years of history before the 19th century, the total amount of gold produced by mankind was less than 10,000 tons, for example, only 200 tons of gold were produced in 100 years in the 18th century. Due to the discovery of a series of gold resources in the 19th century, gold production has increased significantly since then. Especially in the 50 years of the second half of the 19th century, gold production exceeded the total of the previous 5,000 years. In 2013, the world's total gold production was approximately 2,770 tons.

3. Second to none. Can produce extremely thin gold sheets that are easy to roll. An ounce of gold can be hammered down to a thickness of 1/4 million and an area of ??100 square meters. Ancient people hammered it into thin slices and used it to decorate temples and palaces. All these can illustrate the extremely strong flexibility and malleability of gold. The color of gold is golden yellow with metallic luster and is difficult to decompose. Hardness 2-3, pure gold 19.3, melting point 1064.4°C; has good ductility, can be pressed into thin foil, has extremely high heat transfer and electrical conductivity, and the resistance of pure gold is 2.4p. Pure gold has good resistance to chemical corrosion and is the best electroplating material.

4. As a precious metal, gold has good physical properties. "Real gold is not afraid of fire" means that gold is not easy to melt under ordinary flames. High density and heavy feel. Good toughness and ductility, good conductivity. Pure gold has a bright yellow color, but the color changes greatly after being mixed with other metals. For example, gold-copper alloys appear dark red, and silver-containing alloys appear light yellow or off-white. Gold is easily ground into powder, which is why gold is dispersed in nature. Pure gold jewelry is also easily worn and reduced in weight.
