As it is also corrosion resistant, ductile and malleable, its main application is in all types of wiring; from electric energy supply from the power plant to the wall socket, through motor windings for electrical motors, to connectors in computers.
Kuna lisaks sellele on vask korrosioonikindel, plastne ja pehme, valmistatakse sellest eelkõige eri tüüpi juhtmeid, nagu tootja käitisest tarbija pistikupesani viivad elektrijuhtmed, elektrimootorite mähised, arvutite pistmikud jne.
