Electrical steel is an iron alloy which may have from zero to 6.5% silicon (Si:5Fe). Commercial alloys usually have silicon content up to 3.2% (higher concentrations result in brittleness during cold rolling).
The TPRC recommended values are for well annealed 99.998% pure iron with residual electrical resistivity of ρ 0 =0.0327 μΩ⋅cm. TPRC Data Series volume 1 page 169. TPRC Data Series volume 1 page 169.
The good electrical conductivity of plasmas makes their electric fields very small. This results in the important concept of quasineutrality , which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma ( n e = Z > n i ), but on the scale of the Debye length there can be ...

The increase in steel's strength compared to pure iron is possible only by reducing iron's ductility. Steel was produced in bloomery furnaces for thousands of years, but its large-scale, industrial use began only after more efficient production methods were devised in the 17th century, with the introduction of the blast furnace and production ...

An analogous property in electrical engineering and materials science, electric coercivity, is the ability of a ferroelectric material to withstand an external electric field without becoming depolarized. Ferromagnetic materials with high coercivity are called magnetically hard, and are used to make permanent magnets.
