Duralumin is the internal enhancement pushing metal. An Allomancer burning duralumin is able to greatly enhance other metals they are burning. Feruchemists can use duralumin to store connection, and when used as a Hemalurgic spike, duralumin steals an unknown quality.
The duralumin used in the Metallic Arts is ninety-six percent aluminum, four percent copper. 
A duralumin Misting is known as a Duralumin Gnat. An Allomancer burning duralumin instantly uses up any metals being burned simultaneously, releasing an enormous burst of power from those metals. Duralumin itself is not completely consumed like metals it is burned in concert with, but it still continues to burn away at a steady rate.
The use of duralumin could seriously hurt a Mistborn. While burning tin, the Mistborn could be shocked by the sensory overload as well as become temporarily numb, blind, and deaf. A Push or Pull could become so strong it can feel like the Mistborn is being torn apart.
A duralumin Misting gains nothing from his powers.
A duralumin Ferring is known as a Connector. Duralumin is used to store Spiritual connection. For example, filling a duraluminmind can be used to reduce other people's awareness and friendship of the Feruchemist, as these Spiritual connections become stored away.
Tapping the metalmind will allow the user to form stronger connections, possibly depending on what connections was stored. It can allow Connectors to form trust relationships with others much faster, for example.
Duralumin Feruchemy can also change one's Spiritual connection to a planet, which can help worldhoppers with magic systems. Connectors do not have the inherent ability to worldhop, however. Tapping a duraluminmind on a Shardworld other than Sel would prevent a Connector from using Selish magic.
When used as a Hemalurgic spike, duralumin steals some unknown trait or quality.
- If Vin hadn't had duralumin in the fight at the Luthadel Assembly meeting both Elend and she would have died.
- An alternative ending to The Well of Ascension has a conversation about duralumin between Vin and Elend.
- The Lord Ruler kept aluminum and it's alloy duralumin from public knowledge to give the Inquisitors an advantage.
- Brandon wrote the Battle of Hathsin's ending to include Elend burning both duralumin and atium because lots of people had asked about the combination.
