indian septum jewelry wholesale The use of gold in the industry is as follows: It because gold has excellent stability and good conductivity thermal conductivity, the use of gold in the electronics industry is becoming more and more extensive. The development of the Aerospace technology requires more and more radio electronic components with a high degree of stability, such as coatings of high -level vacuum pipes, special use power connections, drawing wires used in special precision electronic instruments, high -frequency conductors, high -temperature welding, high temperature welding Use gold alloy. The gold integrated circuit used in computers, radios, televisions, inclusion machines, etc. According to reports, the demand for electronic industry around the world in 1987 was 123T, accounting for 7.7 % of the total demand. The application of gold in the chemical industry is also unique in the chemical industry, such as materials used in nuclear chemical plants, alloy spray heads for artificial fiber factories.
The gold -plated infrared device and thermal reflector, jet engine and rocket engine used in aircraft and other space transportation tools, gold -lamp heat cover or hot cover plates, aircraft, car, ships and other means of transportation Painted with thin -layer gold, hot glass. In traditional industries such as dental fuses, photos and pen making in traditional industries, the application of gold still has a certain amount of consumption. The application of gold in science and technology is in continuous development.
The expansion information: physical properties 1, color. The steam emitted when the gold is melted is green; its gold powder is usually brown during the smelting process; if it is cast into a thin piece, it can transmit green light. 2, strong ductility. 1 ounce of gold can be pulled into 50 miles long, and its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal. 3, forgedness is the second to none. It can cause extremely thin and easy to roll up. 1 ounce of gold can be hammered to 4 million -foot thick and 100 square feet. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the strong flexibility and forgedness of gold. The color of gold is golden yellow, metal luster, difficult to break down. The hardness is 2-3, the pure gold is 19.3, and the melting point is 1064.4 ° C; it has good ductility and can be pressed into thin foil. It has extremely high heat transfer and conductivity. The resistance of pure gold is 2.4P. Pure gold has good anti -chemical corrosion and is the best electroplating material. Gold, as a precious metal, has good physical characteristics. "Real Gold is not afraid of fire" is that the chemical stability of gold is very high. It is not easy to chemically react with other materials. You don't have to 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. Good toughness and ductility, good guidance. Reference materials: Baidu Encyclopedia-Gold
10k wholesale jewelry Gold is very stable, good conductive performance, soft texture and easy processing, etc., so that gold has a very wide use in electronic products. The modern electronics industry cannot be separated from gold. Some people recycle old electrical appliances to extract gold. In addition, gold resistance high temperature (real gold is not afraid of fire refining), which can effectively reflect visible light and confront cosmic rays. The reflection capacity of infrared rays has reached 98.44%. This use scenario is space. widely.
