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 feel. It has good toughness and ductility and good electrical conductivity. The color of pure gold is bright yellow, but it changes greatly when mixed with other metals, such as dark red gold-copper alloy and light yellow or grayish white silver-containing alloy. Gold is easily ground into powder, which is why gold is dispersed in nature. Pure gold jewelry is also easy to wear, reducing weight.

Therefore, when gold is used to make jewelry, copper and silver are usually added to improve its hardness.
