What is the conductivity of aluminum vs copper? Aluminum has 61 percent of the conductivity of copper, but has only 30 percent of the weight of copper. That means that a bare wire of aluminum weighs half as much as a bare wire of copper that has the same electrical resistance.
Why is copper more conductive than aluminium? Why use copper rather than aluminium as the conductor in power cables? Copper has a significantly lower electrical volume resistivity: 0.017241 (Ω x mm2)/m for copper, compared to 0.0282 (Ω x mm2)/m for aluminium . This difference is highly relevant for power cables.
Is aluminium the best conductor of electricity? Some metals are better conductors of electricity than others.
