As a result of silver's higher cost, silver wire and solder are a niche product. While copper is used in wires, connectors, printed circuits and other electrical parts across a number of industries, silver is generally used as a component in specialty electronics and sensitive systems, like industrial-grade switches and automobile contacts.
Uses of Gold in the United States: This pie chart shows how gold was used in the United States in 2017, not including gold bullion. The main uses were in jewelry (38%) and electronics (34%). The minting of official coins accounted for 22% of the gold used, and 6% was for other uses.
The electrical resistivity is particularly important because it will determine its electrical performance and hence whether it is suitable for use in many electrical components. For example it will be seen that the resistivity of copper, the resistivity of aluminium and that of silver and gold determines where these metals are used.
Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics. 2. Reactivity: Metals are very reactive, some more than others, but most form compounds with other elements quite easily. Sodium (Na) and potassium (K) are some of the most reactive metals.

Mar 28, 2016· Electric conductivity is the movement of electrically charged particles. All metals conduct electricity to a certain extent, but certain metals are more highly conductive. The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal …
Jul 10, 2002· Why is gold used in electronic products as a conductor instead of silver? I believe silver is the better conductor of the two metals, but sometimes they seem to use gold instead of silver. Could this be because the electricity passes on the surface of the metal and silver's surface is more easily tarnished than that of gold which doesn't tarnish?

"Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint. Extra-easy solder contains 56% silver and has a melting point of 618 °C (1,145 °F).

Here are some of the most common modern uses for precious metals. Gold. The word "gold" is synonymous with status and stature, and has been throughout history.
For one, silver is typically a less expensive alternative for metal finishing electronics. Silver also provides excellent electrical and thermal conductivity. Because of its low contact resistance, silver plating for electronics is often used to provide a coating on highly active copper parts.
60. Photography: While on the wane, silver it still used in color film photography. Silver halides are used in a gelatin process with film and paper to process film due to their light sensitive features. 61.
