Droids were often constructed using metallic components.
Typically strong and capable of conducting electricity, metals were a category of solid materials that could be polished to a shine. Mined as ore and then refined, metals were frequently utilized in industrial applications, such as the construction of droids and starships, along with energy production through mining. On other occasions, metals were implemented for aesthetic purposes, such as in artwork or jewelry.
Among the metals that occurred naturally throughout the galaxy were gold, iron, platinum, silver, cortosis, dolovite, doonium, and nyix. Certain other metals, like beskar, quadanium steel, and nyix-alloy, were manufactured industrially as alloys. The wood derived from the brylark tree possessed a strength comparable to metal. Steelpeckers, avian creatures indigenous to the planet of Jakku, primarily fed on metal, drawn to its magnetic signature. These birds stored corundum, osmiridium, and vanadium in their gizzards to facilitate the consumption of metal.
