The list of most conductive metals includes silver, copper and gold. The conductivity standard of metal is based on silver, which is the most conductive of all metals.Continue Reading
Conductivity is defined as the ease with which an electric charge or heat passes through a metal. A conductor gives little resistance to the flow of electric current or heat, which means that a conductor allows an electric charge to flow freely through it. Conversely, an insulator resists the flow of electricity. Ceramics, wood and plastics are considered insulators. Thermal conductivity refers to the ease with which heat passes through a conductor or insulator. Electrically conductive metals typically are also thermally conductive.
From most to least conductive, the top 10 metals are:
The conductivity of all metals is compared to that of silver. On a scale of zero to 100, where 100 represents the most conductive, silver ranks 100. In addition to being a strong electrical conductor, silver does not make sparks easily. It is used in electrical components like contacts and circuits. It is important to note that gold rates a 76 on the conductivity scale. Popular belief suggests that gold is a better conductor than silver, but facts prove this assumption to be false.Learn more about Chemistry
Zinc is usually found in mineral deposits that include copper, lead, iron and other base metals. Its primary ore is sphalerite, which accounts for about 95 percent of zinc produced worldwide. China is the largest zinc producer, followed by Peru, Australia, India and the United States.Full Answer >
Stainless steels are iron alloys that contain 10.5 percent chromium and can be enhanced with other metals, such as copper, titanium, molybdenum and nickel. Stainless steel can also be improved for various applications by adding non-metals to its structure, such as nitrogen and carbon. The chromium-rich oxide layer on the surface of the steel makes for an alloy that is easily repairable.Full Answer >
Nickel silver is an alloy made from 50 to 80 percent copper, 5 to 30 percent nickel, and 10 to 35 percent zinc. Although it is silvery in appearance, it is non-precious and contains no silver.Full Answer >
White gold is an alloy of gold and other metals, such as silver or palladium, while platinum is an almost entirely pure white metal. In a natural state, platinum has a much whiter color than white gold. However, most white gold is plated with rhodium, which makes the colors much more similar.Full Answer >
