To get an electrical current to flow through metals, the power source has to fight against resistivity. The lower the level of resistivity, the more electrical conductivity a metal has. And since copper wire has a low level of resistivity, it’s a fantastic electrical
While aluminium can also be used for everything electrical, copper has the upper hand for several reasons. For starters, aluminium has lower conductivity than copper and is also more prone to oxidation. The aluminium oxide that forms on the surface is not conductive like copper oxide
Copper prices have surged in 2021. The base metal remains in high demand, much thanks to its need in green energy projects and electric cars. In May 2021, commodities analysts at Goldman Sachs called copper ‘the new oil.’ That’s because electric cars need several times more copper than their gas-powered counterparts.
