This table presents the electrical resistivity and electrical conductivity of several materials, including copper, gold, platinum, glass, and more.
The SI unit of electrical conductivity is siemens per metre (S/m). Resistivity and conductivity are intensive properties of materials, giving the opposition of a standard cube of material to current.
This page is a table of electrical conductivity and resistvity for copper and copper alloys.
Resistivity is the opposite of the electrical conductivity of metals, evaluating how strongly a metal opposes the flow of electric current. This is commonly measured across the opposite faces of a one-meter cube of material and described as an ohm meter (Ω⋅m).
Electrical conductivity is a measure of how well a material transports an electric charge. This is an essential property in electrical wiring systems. Copper has the highest electrical conductivity rating of all non-precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C.
Electrical Conductivity Electrical conductivity or specific conductivity is the measure of a material's ability to conduct electric current. Conductivity is the reciprocal (inverse) of electrical resistivity .
Copper – Electrical Resistivity and Electrical Conductivity Electrical resistivity of Copper is 16.8 nΩ·m . Electrical resistivity and its converse, electrical conductivity , is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current.
Some materials that have high conductivity include copper and aluminum. Electrical conductivity is the measure of how easily electricity flows through a material. Conductivity vs Resistivity
When used for connectors or other electrical applications, the inherently high electrical conductivity of copper and copper alloys is very important. The conductivity of copper is expressed in units of a percentage of IACS (International Annealed Copper Standard).
Electrical conductivity is the primary characteristic that distinguishes copper from other metals. Of the commercially useful metals, copper is only surpassed by silver. But copper alloys have a wide range of conductivity.
