Electrum is the internal temporal pushing metal alloy made from gold and silver. An Allomancer burning electrum is able to see who they may become in the future, depending on their choices. Feruchemists can use electrum to store determination, and when used as a Hemalurgic spike, electrum steals an unknown quality.
The electrum used in the Metallic Arts is forty-five percent gold, fifty-five percent silver. 
A electrum Misting is known as an Oracle. Burning electrum will reveal possible futures of the Allomancer up to several seconds, by casting shadows of oneself like atium shadows. Electrum's main usage is its ability to counter atium, in this regard and the fact that gold and silver are relatively cheap compared to atium Elend called it "poor man's atium".
While burning electrum the user's future will not be revealed to an enemy Allomancers burning atium. Instead, it will cause the user's observed atium shadow to split, preventing the enemy Allomancer from predicting one's actions.
When used as a Hemalurgic spike, electrum steals some unknown trait or quality.
- Brandon made a mistake while writing The Well of Ascension. The Feruchemical effects of brass and electrum were to be swapped. By the time he realized this was forgotten, however, the book was already in print. Brandon didn't want to retcon this, so the effect of electrum was canonized.
