Duralumin
itemThin silvery reflective bar along with a pouch of dust, composed of an aluminum-copper alloy. Extremely lightweight secret 9th Allomantic metal. Burns to enhance the power of other metals being burned simultaneously without immediate standalone effect.
Introduced in *The Well of Ascension* as a secretive ninth Allomantic metal—an ultra-lightweight aluminum-copper alloy—Duralumin manifests no standalone effect but dramatically amplifies the power of other metals burned simultaneously, enabling godlike bursts of Allomantic might. By *The Hero of Ages*, its composition expands to include manganese and magnesium, fueling explosive burns that obliterate all nearby metal reserves in a single, cataclysmic surge. This evolution underscores Duralumin's pivotal role in escalating Mistborn combat dynamics and thwarting Preservation's manipulations amid Ruin's apocalypse.
