About Common Precious Metals–Gold and Silver

Gold is best known for its use in jewelry, coins and bullion. At the same time, it is also important in different industrial applications. Gold is highly reliable and durable as a conductor and connector, with excellent resistance to corrosion, contamination, high temperature and humidity. Gold-plated connections are commonly found in electronic devices such as cell phones, computers and laptops, calculators, Global Positioning System (GPS) units, medical equipment, and more.
Gold is coated on different materials in different industries. In the aerospace and defense industry, gold connections in spacecraft provide stable and durable performance under extreme conditions, and gold-coated polyester films are often used to protect spacecraft from infrared radiation. A thin layer of gold can also be found on the astronaut's spacesuit helmet to protect the astronaut. Likewise, for specialty glass used in climate-controlled buildings, gold is dispersed in the glass or plated on the surface, which reflects solar radiation.

Silver (Ag) is a rare and precious precious metal. In addition to its use in jewelry and coins, silver is used in a wide range of industrial applications due to its unique properties: good corrosion and oxidation resistance, optimal thermal and electrical conductivity, high ductility and ductility, antibacterial and non-toxic properties, high gloss and reflectivity, and excellent photosensitivity.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/19194.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/19194.html
