The way of hoarding gold can be called pure "gold investment". Investors do not need to carry heavy gold home, but only need to buy financial products with gold as the target, which is a more efficient and convenient way to invest in gold. For example, buy paper gold in the bank and gold spot and futures contracts in the exchange. The underlying assets of these wealth management products are all gold, but for ordinary investors, there are still some obstacles in actual transactions. For example, the spread trading method of paper gold has the problem of high transaction rate, and the trading account opening process of spot gold and futures is complicated, and the trading threshold is relatively high.

1. second to none. It will cause extremely thin gold sheets to roll up easily. Gold weighing 1 oz can be hammered down to 1 ft, 100 m2. The ancients hammered it into thin slices and spread it in temples and palaces for decoration. All these can explain the flexibility and ductility of gold.

2. The color of gold is golden yellow, which has metallic luster and is not easy to decompose. The density is 19.3g/cm3 and the melting point is1064.4℃; Good ductility, can be pressed into thin foil, and has extremely high heat and thermal conductivity. The resistance of pure gold is 2.4P Pure gold has good chemical resistance and is the best electroplating material.

3. As a precious metal, gold has good physical properties. "Real gold is not afraid of fire" means that gold has high chemical stability and is not easy to react with other substances, so there is no need to worry about oxidation and discoloration. Even in the molten state, it will not be oxidized and discolored, and it will still be golden yellow after cooling. High density and heavy touch. Good toughness and ductility, good electrical conductivity. Pure gold is bright yellow, but the color changes greatly after mixing with other metals, such as gold-copper alloy is dark red, and silver-containing alloy is light yellow or grayish white. Gold is easily ground into powder, which is also the reason why gold is dispersed in nature. Pure gold jewelry is also easy to wear and lose weight.

4. In Mendeleev's periodic table of elements, the atomic number of gold is 79, that is, the nucleus of gold contains 79 protons with positive charge. At the same time, gold has good chemical stability because it conforms to the half-full law. In the metal market, gold and ruthenium, rhodium, palladium, osmium, iridium, platinum and other metals are collectively called precious metals.

Although gold is a very soft metal, it is not as good as lead and tin. Nails can be used to draw marks on pure gold, which makes gold very easy to process. But this is not ideal for the manufacturers of decorations, because it is easy to scratch the decorations, make them lose their luster and even affect their appearance. Therefore, when gold is used to make jewelry, copper and silver are usually added to improve its hardness.
