Aluminum metal (and some of its alloys) are "Allomantically inert" -- they cannot be [[steel|Pushed]] or [[iron|Pulled]], and can shield people from emotional Allomancy.{{book ref|mb4|part=ars}}{{wob ref|15745}} Aluminum generates no [[atium|atium shadows]]{{wob ref|6870}} and can create dead zones within [[cadmium#Allomantic use|cadmium]] and [[bendalloy#Allomantic Use|bendalloy]] bubbles, where the shielded area is not included within the time bubble.{{wob ref|4297}} It also interferes with [[Gold#Feruchemical Use|Feruchemical healing]], by making it impossible for wounds to heal around the aluminum until it is removed from the body. There is a similar effect on [[Pewter#Allomantic Use|pewter Allomancy]].{{wob ref|6365}}

A significant percentage of the aluminum in the [[Elendel Basin|Basin]] is produced by the [[Ghostbloods]]. [[Dean]], the Scadrian branch's chemist, believes that the Scadrians would one day discover how to create it via electrolysis, and that the value would plummet to being cheaper than [[tin]]. The Ghostbloods have been using their aluminum to fund their operations for the past two decades.{{book ref|mb7|40}}

The paired alloy of aluminum used in the Metallic Arts is [[duralumin]].

An aluminum [[Misting]] is known as an '''Aluminum Gnat'''. Burning aluminum causes the body to instantly metabolize its metal reserves without any other effect.{{wob ref|2461}} As such, an Aluminum Gnat gains no useable powers from their Allomancy,{{book ref|mb4|part=ars}} however, it can be used to negate effects of other Investiture, such as the withering effect of [[Shade]]s on [[Threnody]].{{wob ref|6374}} Only Allomantically relevant metals can be burned away.{{wob ref|12563}} Allomancy does not affect aluminum even though the metal itself is Allomantically viable.{{book ref|mb1|36}}

Because aluminum can shield against emotional Allomancy, those who can afford to often wear hats with an aluminum lining.{{book ref|mb5|1}} It can also be used to block [[bronze#Allomantic Use|Allomantic bronze]].{{wob ref|8897}}

An aluminum [[Ferring]] is known as a '''Trueself'''. Aluminum is used to store "spiritual sense of [[Identity]]." This ability is not fully understood, and is rarely discussed outside of Terris communities.{{book ref|mb4|part=ars}} A Trueself who fills an aluminummind to the point where they have no Identity and then fills another metalmind is able to produce a metalmind that any Feruchemist with the relevant power can tap. In a similar manner, a Feruchemist may be able to tap another person's metalminds by filling their own aluminummind completely.{{book ref|mb6|3}} Trueselfs can heal damage done to them in the [[Cognitive Realm]] by storing Identity, but it takes a roundabout method.{{wob ref|7836}} Storing Identity makes the Feruchemist more susceptible to many things, such as [[Forgery]].{{wob ref|3547}}

On Scadrial, guns and bullets made from aluminum are highly effective (albeit expensive) because they cannot be [[steel|Pushed]], [[iron|Pulled]], or even detected using the sight granted by steel or iron Allomancy. Aluminum bullets are actually composed of an Allomantically inert alloy of aluminum since the ballistics of a pure aluminum bullet would not work.{{book ref|mb4|7}}

Aluminum can be produced with [[Soulcasting]].{{book ref|sa2|48}} However, aluminum resists attempts to Soulcast it into other [[Ten Essences|Essences]].{{wob ref|8306}} [[Shardblade]]s are unable to cut aluminum through magical means but would be able to cut it physically, like a conventional blade, if the aluminum were thin enough.{{wob ref|1442}}{{epigraph ref|sa4|17}} Aluminum can block [[spanreed]] communication, and can prevent Soulcasting from being detected by others.{{book ref|sa3|81}} Aluminum cannot be affected by the [[Surge]]s [[Adhesion]] or [[Gravitation]].{{wob ref|8423}} It interferes with most Radiant powers.{{epigraph ref|sa4|17}}

This experimentation accidentally resulted in a series of modified fabrials in which the mechanism contained bits of aluminum foil that blocked certain functions, but not all. Among these were a spanreed that transferred lateral motion, but not vertical; a lift to permit [[Rysn]] to move between decks of the ''[[Wandersail (1174 ship)|Wandersail]]'' and a number of "wheelchair" fabrials which levitated and permitted [[Rysn]] to maneuver while seated using a partially aluminum-blocked counterweight.{{book ref|sa3.5|9}} These are particularly useful due to a known drawback of motion-transferring fabrials caused by a moving frame of reference (e.g. a moving ship at sea communicating by spanreed to shore).

The Knights Radiant once lined tunnels deep beneath [[Urithiru]] with ralkalest, likely to protect against intrusion into the tunnels from the foothills below via Surgebinding. It is unknown whether the term ralkalest is of Selish origin alone, or if Raboniel learned of it from another source.{{book ref|sa4|37}}

=== Lumar ===

Aluminum lined rooms{{book ref|tress|22}} and boxes are used to protect [[Aether spores]] from [[silver]].{{book ref|tress|23}} It is said to "block" the effect of silver.{{book ref|tress|38}}
