Iron stores physical weight. Iron is used to store physical mass, or more accurately, density. This is accomplished by changing the Feruchemist's mass, not by changing the effect of gravity on the Feruchemist.{{qa ref|689|3|text=Does iron store mass or weight?|date=17 March 2012}} The greater density has no effect on the Feruchemist's vulnerability to penetration.{{annotation ref|aol|chapter=6}} Tapping iron grants the Feruchemist the strength required to remain standing. Similarly, when a Feruchemist stores their weight, their muscles are weakened slightly.

Steel stores physical speed. Tapping steel will allow the Feruchemist to move at amazing rates, while storing it will cause the Feruchemist to move more slowly. Storing speed has negligible if any effect on the Feruchemist's ability to speak.{{book ref|mb2|50}} It seems that steel Ferrings are able to make at least basic decisions while using speed.

Brass stores warmth. Tapping brass will make the Feruchemist warmer. While filling a brassmind the Ferring is actively cooled.

Nicrosil allows one to store [[Investiture]]. This is a power that very few know anything about, and the people of Terris do not truly know what they are doing when they use this power. In Bands of Mourning, this power is used to grant the power of Feruchemy or Allomancy to people who were not born with it.

Aluminum stores a spiritual sense of identity. This is an art rarely spoken of outside of Terris communities, and even among them it is not yet well understood. In Bands of Mourning, the sense of identity is something relating to Feruchemy mainly. The identity of a metalmind is what makes it so that one Feruchemist cannot use another's metalmind. If, however, a Feruchemist creates a metalmind while filling an aluminummind, the metalmind will be identity-less, allowing for any Ferring of the same metal to use it. This is how Wayne is able to use the goldmind he acquired in New Seran, even though he did not fill it himself.

Duralumin stores spiritual connection. Reducing other people's awareness and friendship with them during active storage. Tapping it can help speedily forming trust relationships with others. While tapping a duraluminmind, the user also becomes imbued with the culture of the area they are currently in. In Bands of Mourning this is used for the tribal people of the south to communicate with the protagonists from Elendel.
