Items can be [[Soulcasting|Soulcast]] into aluminum.{{wob ref|7942}} 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}} 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 likely cannot be affected by any Surge.
 
Highmarshal Azure was given metal sheets by [[Wit]] during her time in Kholinar that were possibly aluminum. When lining a room, they allowed for the use of Soulcasting fabrials[[fabrial]]s without detection by the [[Voidspren]].{{book ref|sa3|81}}
 
The Unkalaki people are able to obtain aluminium by trading with the spren world, and are aware that it has an effect on spren.{{book ref|sa3.5|7}}
 
During the expedition to Aimia, [[Rushu]] is tasked by [[Navani]] to experiment with aluminum and discover the details of its impact on fabrials. She first notes that the thickness of the metal may impact its effect on fabrial operation (e.g. block vs modify).{{book ref|sa3.5|7}} After tinkering with a spanreed and aluminum foil, [[Huio]] theorizes that the spren react to aluminum "almost like prey react to a predator" and that it interferes with the spren's ability to sense thoughts.{{book ref|sa3.5|7}} [[Rushu]] further theorizes that each axis of motion and rotation could be blocked separately by proper application of aluminum. It is likely that other types of [[fabrials]] (i.e. heating fabrials) could be modified similarly.
 
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]] 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).
