Tokyo Olympic gold medal, once picked, "stripped". What is the raw material for the gold medal in Tokyo Olympic Games?

At the just-concluded Tokyo Olympic Games, China athletes showed their grace and won 38 gold medals. Since the 20th century, China athletes have made great achievements in every Olympic Games. The reason is inseparable from the usual hard training and excellent sports guidance. Speaking of Olympic gold medals, the materials used in each Olympic Games are very different. The gold medal of the Beijing Olympic Games is covered with gold, but it contains suet jade, which is very in line with the culture of China.

Netizens are dissatisfied. In the 1996 Olympic Games, the gold medals used cost about 2 10000 US dollars, which is also called the most expensive Olympic gold medal. This Tokyo Olympic Games has made many netizens dissatisfied and aroused people's dissatisfaction all over the world, whether it is the referee's penalty scale, the living environment of athletes in the Olympic Village, or Japan's prevention and control of the epidemic. After the Olympic Games, there was a phenomenon that Olympic athletes lost their skins when they issued Olympic gold medals in Weibo.

As early as before the Olympic Games, Japan claimed that the Olympic gold medals were made of precious metals extracted from old household appliances. The gold plating on the outside is only 6 grams, and the cost is about 5000 yuan. First of all, it is true that no Olympic gold medal is pure gold, because the cost is too expensive, which will bring a great burden to the expenses of the Olympic Games. However, gold medals in bean curd residue projects like the Tokyo Olympic Games are really rare, because precious metals extracted from old household appliances are used internally and are plated with a layer of gold, so that once the production process is unstable, the skin will fall off.

Quality problem Olympic gold medal is something that every athlete dreams of. It needs to be hung in the most conspicuous place at home and passed down all the time. It is such a precious gold medal that you are so careless when you do it. No wonder netizens have such a big opinion about this Winter Olympics. Extravagance and waste are really not desirable, and it is also desirable to use precious metals in old household appliances as raw materials. However, poor production technology leads to problems in the quality of gold medals, which is a disrespect for athletes and the Olympic spirit.
