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 feel. It has good toughness and ductility and good electrical conductivity. Pure gold is bright yellow, but its color changes greatly when mixed with other metals such as dark red gold-copper alloy, 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.
In Mendeleev's periodic table, the atomic number of gold is 79, that is to say, the nucleus of gold contains 79 positively charged protons. At the same time, gold has good chemical stability because of its semi-regularity. 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. Nail prints can be painted on pure gold. This softness makes gold easy to process. But this is not ideal for accessories manufacturers, because it is easy to scratch the accessories, make them lose luster, and even affect the appearance. Therefore, when making jewelry, gold, copper and silver are generally added to improve the hardness of jewelry.
