Gold and silver are used more in those places.

gold is the most basic use of gold as gold ornaments (including jewelry, Buddha statue decoration, architectural decoration, etc.) and gold utensils. If there is any change, it is that gold ornaments are increasingly moving from palaces and temples to the people, from the privilege of dignitaries to mass consumption. Now more than 8% of the world's gold supply is absorbed by the jewelry industry every year.

due to the high price of gold and the relative scarcity of resources, the industrial use of gold is limited, and the proportion of industrial gold in the world's total demand is less than 1%. However, some experts believe that jewelry gold will tend to be stable in the future, and the growth of industrial gold will be an important force to drive the change of gold supply and demand structure, so the commercial use of gold needs to be explored in many ways.

At present, gold commodities are mainly used in jewelry industry, electronics industry, dentists, gold medals and other industrial gold. It should be admitted that the commercial use of gold is still very narrow at present, which is also the result of gold being strictly controlled by the state as a monetary metal for a long time. In the future, with the advancement of the reform of the international financial system; The regression trend of financial gold's commodity attribute is strengthened, and the expansion of gold commodity demand will be of more significance to the development of gold industry. Silver is a beautiful silvery white metal. Silver jewelry and silverware have good reflectivity, which can reach high brightness after polishing, and are widely used in jewelry and home decoration. First, silver has good ductility, and its conductivity and heat transfer are the highest among all metals. Therefore, silver is often used to make highly sensitive physical instrument components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contact points in all these devices are made of silver. During use, each contact point has to work for millions of times, and it must be wear-resistant and reliable, and can withstand strict working requirements. Silver can fully meet all kinds of requirements. Secondly, it is used to make alloy, flux, silver foil, silver salt, chemical instruments, etc., and it is also used to make silver coins and bottom silver. Silver coins used to be the legal tender of the silver-based countries, which prevailed for a while. However, with the reform of monetary system and the emergence of credit currency, silver coins gradually withdrew from the circulation field. Thirdly, silver is of great significance in the manufacture of photographic photosensitive materials. Because photographic paper and film are coated with sensitizers, which are all silver compounds-silver chloride or silver bromide. Today, the world's annual silver used in film and photography has reached 15 tons.

having said that, I think you can consider these two sentences: now more than 8% of the world's gold supply is absorbed by the jewelry industry every year. Silver coins currently cast by silver are mainly investment silver coins and commemorative silver coins. In fact, doing business is investment. Success depends on the accuracy of your grasp of the current main market and the forecast of future market development needs! I hope you can adopt it, and I wish you success and wealth!
