Brass current density
WebThis is because the resistivity to electron transport in metals at room temperature originates primarily from scattering of electrons on thermal vibrations of the lattice, which are relatively weak in a soft metal. The maximum permissible current density of copper in open air is approximately 3.1 × 10 6 A/m2 of cross-sectional area, above ... WebAug 4, 2010 · In laboratory environments, corrosion currents are sometimes expressed in μA cm−2with 1 μA cm−2being equivalent to 10 mA m−2. Reinforcing steel corrosion rates of 1 mA m−2or less are considered to be negligible and are not likely to cause disruption of the concrete cover.
