The standard is most often used as a comparative property in the specification of the conductivity of other metals. For example, the conductivity of a particular grade of titanium may be specified as 1.2 % IACS, meaning that its electrical conductivity is 1.2 % of the copper specified as the IACS standard. [2]
Conductivity is generally specified relative to the 1913 International Annealed Copper Standard of 5.8 × 10 7 S/m. Advances in the refining process now yield OF and ETP copper that can meet or exceed 101% of this standard. (Ultra-pure copper has a conductivity of 5.865 × 10 7 S/m, 102.75% IACS.) Note that OF and ETP coppers have identical ...
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
The electrical conductivity of silver is 106% of that of annealed copper on the IACS scale, and the electrical resistivity of silver = 15.9 nΩ•m at 20 °C. [ 14 ] [ 15 ] The high cost of silver combined with its low tensile strength limits its use to special applications, such as joint plating and sliding contact surfaces, and plating for ...
Aluminium alloy 2024 has a density of 2.78 g/cm 3 (0.1 lb/in 3), electrical conductivity of 30% IACS, Young's modulus of 73 GPa (10.6 Msi) across all tempers, and begins to melt at 500 °C (932 °F). [ 4 ]
Keith Urban was doing some wishful thinking when he wrote his romantic chart-topper “Somebody Like You” — much to the chagrin of his then-girlfriend.. Urban, 57, said in a Jan. 20 interview ...

By saving and investing, you might not end up as wealthy as the top 0.01% of Americans, but as the chart above shows, you can still do pretty well. You just need to have a plan -- and to stick to ...
