Materialρ [Ω·m] at 20°Cσ [S/m] at 20°CSilver, Ag1.59 × 10−86.30 × 107Copper, Cu1.68 × 10−85.96 × 107Aluminum, Al2.82 × 10−83.50 × 107copper has a high conductivity.but silver has more conductivity than copper but due to cheapness copper being preferred, The main things where copper is used is for electrical applications, such as building wire, motor windings, cables and bushbarsSilver is 6% more conductive than copper, but due to cost it is not practical in most cases. However, it is used in specialized equipment, such as satellitesAluminium wire is the most common metal in electric power transmission and distribution Although only 61% of the conductivity of copper by cross-sectional area, its lower density makes it twice as conductive by mass. As aluminum is roughly one-third the cost of copper by weight, the economic advantages are considerable when large conductors are required.0Modal content
