Use of gold

Because gold has good physical and mechanical properties, corrosion resistance and high chemical stability, it is widely used.
Because of its golden color and easy processing properties, gold has been used in jewelry and decorations since ancient times. According to statistics, in 1987, the world's manufacturing of jewelry used gold reached 1,100 tons.
Gold has a high chemical stability, so gold has long been used as a metal for making money, and it is still the most important currency in the world. Money has five functions, namely, the value scale, the means of circulation, the means of storage, the means of payment, and the world currency. All currencies have only five functions at the same time. Therefore, gold is the world currency. Among all the currencies, only gold has these five functions. So gold is the world currency, hard currency and value-preserving metals. The international use of gold reserves as one of the important indicators to measure a country's ability to pay and economic strength.
In modern industry, the most used gold is the electronics industry. In 1985, the world only used computer circuit manufacturing, the amount of gold used was 111 tons. In the application of gold on the circuit, the coating is usually coated with a very thin gold film, which can achieve higher efficiency at lower voltage, which is impossible for other metals. Such circuits are used, for example, in modern world-class transient imaging cameras.
In the aerospace industry, spark electrode plugs for engines are made from alloys of gold. Because of its good yellow absorbance and a reflectivity of 94.4%, it is militaryly used to defend missiles and to defend against heat radiation from common heat sources.
In the chemical industry, gold is used as a coating for steel pipes to transport corrosive substances. In the construction industry, gold is used as an advanced insulation medium for modern building windows. The surface of the glass is coated with a gold film of less than 1 micron to maximize the passage of natural light, which is insulated during the winter and reflects the sunlight during the summer. This type of glass is also used in trains, cars and large passenger aircraft. The gold film can remain uncontaminated and performance after being energized. The heat reflection of the gold film can also be applied to solar collectors.
Gold has also been used in medical applications because of its high chemical stability and easy processing properties. It is used for dental implants in the ENT; gold radioisotopes are used for the diagnosis and treatment of arthritis and malignant tumors; and gold foil is used to treat burns and skin. Ulcers, etc.
In addition to the above, gold alloys can also be used to make instrumentation parts and contacts; used to make case and nib. Gold alloy products are highly reliable and have a long life.

Farm Fence

QYM-Farm Fence Farm fence, also called field fence or grassland fence, is kind of fence fabric automatically woven by high-tensile galvanized wire. Vertical (stay) wires are woven or wrapped around the horizontal (line) wires to form rectangular openings in different size.Farm fence can be used with stakes, wood timber and other post. Made of high tensile steel wire, this kind of wire fence is strong for keeping and breeding animals. Farm fences we offer have innovative and firm structure, flat surface, uniform opening and good integration. This product offers good flexibility;good pressure resistance, corrosion resistance and weather resistance properties and can serve for a very long time. Even the cut pieces will not deform under pressure. It has excellent corrosion resistance and antioxidizing property. Unlike the welded wire mesh fences with the welding spots getting easily broken, our grassland fences are firm forever once installed and make the best materials for protecting grassland, forestry,highway and environments.
