Doonium

Doonium is a rare and valuable metal in the Star Wars galaxy, known for its exceptional strength and density. Its primary use is in starship construction, particularly for the hulls and structural components of large warships and space stations. Doonium's durability makes it an ideal material for enduring the stresses of space travel and combat. The Galactic Empire, in particular, utilized vast quantities of doonium in the construction of the Death Star superweapons.

The mining and refining of doonium are complex and resource-intensive processes, often necessitating the control of specific planetary systems that are rich in doonium ore. Planets such as Sevarcos and Pamarthe have been noted for their doonium deposits. Because of the metal's critical importance, control over these planets and their doonium resources often becomes a strategic priority for various galactic factions, from the Separatists during The Clone Wars to the First Order in the sequel trilogy era. Consequently, doonium's rarity and strategic value make it one of the most coveted resources in the galaxy.
