Joanna
Gold can't be oxidized for many years, and gold will not be oxidized. Gold is a single -quality form of chemical element gold. It is a soft, golden, precious metal with antioxidant and corrosion. Gold is one of the rare, precious and extremely valued metals. The international gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments. physical properties:
Gold as a precious metal, with good physical characteristics, "real gold is not afraid of fire refining" is the high chemical stability of gold, which is not easy to occur with other materials chemistry Reaction, don't worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. The density is strong and the feel is heavy. The toughness and ductility, good guidance. Pure gold has gorgeous yellow, but after incorporating other metals, the color changes greatly. For example, 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 above content refers to Baidu Encyclopedia — Gold
