Gold is soft because of the ductility and forgedness of gold. The strong ductility. 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. although gold is a very soft metal, it is not as good as lead and tin metal. Use nails on pure gold to draw traces. This softness makes gold very easy to process. However, this point is not ideal for the maker of the decoration, because it is easy to make the decorations hurt and make it make it make it wound and make it it. Lost luster and even affect beauty. So when making jewelry with gold, copper and silver must be added to improve their hardness. It gold is forged and easy to extend, which can be crushed to a transparent and transparent green foil with a thickness of 0.001 mm. 0.5 grams of gold can be pulled into a 160 -meter -long golden. This can cause extremely thin and easy to roll. 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 expansion information: 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. 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. A even if it is melted, it will not be oxidized and discolored, and the golden glitter is still glitter after cooling. The density is strong and the feel is heavy. Good toughness and ductility, good guidance. It pure gold has gorgeous yellow, but the color changes greater after mixed with other metals. For example, the gold and copper alloy are dark red, and the silver alloy is light yellow or gray -white. Jin Yi was grinded into powder, which is why Jin is scattered in nature. Pure gold jewelry is also easily worn and reduced. The atomic order in the Menjiev cycle table is 79, that is, the golden nucleus of the gold contains 79 protons, and the proton belt is positive. At the same time, because it is in line with half full rules, gold has good chemical stability. In the metal market, metals such as crickets, 铑, 钯, 锇, 铱, and platinum are collectively referred to as precious metals References Source: Baidu Source: Baidu Encyclopedia -Gold

This is determined by the physical attributes of gold! Gold's softness is good, easy to forge and extension. The hardness of gold is low, and the hardness of the mineral is 3.7,
