wholesale jewelry.com This statement is right. Because of their chemical properties, gold and silver are not easy to rust.
Min is a non -lively metal element. It does not respond to oxygen under normal temperature or heating conditions. It can only be dissolved in the corrosive (oxidative) mixture such as king water, selenium, alpine hydrofluoric acid, and nitric acid. ) Strong material.
The physical and chemical properties of the silver are relatively stable, the heat conduction and electrical conductivity are very good, soft, and rich in ductility. Its reflective rate is extremely high, up to 99%.

The application of gold
1. In the electronics industry
Good conductivity thermal performance, so the use of Jin 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. Tujin integrated circuits used in computers, radios, televisions, inclusion machines, etc.
2. In the chemical industry
It also has unique uses in the chemical industry, such as materials for nuclear chemical plants, alloy spray heads for artificial fiber factories.
3. In the space industry
In in the aerospace industry, the use of gold is also under development and development. The gold -plated infrared device and thermal reflex used in aircraft and other space transport tools, jet engines and rocket engines are applied with gold anti -heat cover or heat shelter, as well as transport tools such as aircraft, automobiles, and ships. Glass and so on.
4. In traditional industries
among traditional industries such as denture industry, photography and pen making, the application of gold still has a certain amount of consumption. The application of gold in science and technology is in continuous development. Qiu Hongliang's three -time cash crystal accumulation at an atomic institute in Japan can constitute a superconducting thin film.

cheap wholesale mens jewelry Because the business of operating chemistry is not lively, it is not easy for gold and silver jewelry to admire outstanding pollution and it is easy to save. This sentence is wrong.
happy girl jewelry wholesale It is right in terms of chemical nature, but what is in actual life is wrong. Gold and silver jewelry will form dirt on the surface without cleaning up for a long time. This kind of dirt is more difficult to deal with, so it still needs to be cleaned regularly. Gold and silver jewelry are not placed there, whether it is easy to save, but also consider using it without maintenance.
