This mainly determines the physical properties of gold. The following introduces the physical properties related to the long necklace pull: The ductility: abnormal strong. 1 ounce of gold can be pulled into 50 miles long. Its good ductility makes it easy to cast and is a good choice for making jewelry. It can be pressed into thin foil. Forgedness: Benefit and fingertips. It can cause a gold piece that is very thin and easy to roll up. 1 ounce of gold can be hammered to 1 foot of 1 foot of 4 million and 100 square feet. The ancients hammered it into thin slices and fell into a temple and the palace for decoration. It is said that 1 ounce of gold can be used to fill the top cover of a house. The two metals of lead and tin can be traced with nails on pure gold. This softness makes gold very easy to process. Decoratives are injured to lose their luster and even affect the beauty. Therefore, when making jewelry with gold, copper and silver must be added to improve their hardness. It gold is easy to forge, easy to extend, and can be crushed into thickness to be to be thick. 0.001 mm transparent and transparent green gold foil .0.5 grams of gold can be pulled into 160 meters long gold silk. The compressive strength of pure gold is 10kg / mm2. Generally between 10-30kg/ mm2. When the cold pull gold, the strongest force is the largest.
, because the gold itself is too soft, when the gold necklace is too thin and the alloy ratio is not proper (especially Pure gold is easier to be stretched), and it will be stretched because of its own weight, especially the artificial tension.

Both gold and silver are easy to deform. After a long time, it will naturally become thinner and thinner
The gold is too soft and easy to deform.
