This table gives the electrical resistivity, in units of 10–8 Ω m, for 65 metallic elements at common room temperatures (293 K and 298 K). The data refer to polycrystalline samples. The number of significant figures indicates the accuracy of the values. The Online Edition of the CRC Handbook contains resistivity values at temperatures ranging from 1 K to 1000K. Note that at low temperatures (especially below 50 K) the electrical resistivity is extremely sensitive to sample purity. Thus, the low-temperature values refer to samples of specified purity and treatment. The references should be consulted for further information on this point, as well as for values at additional temperatures.
