Awakening Aluminium

[The Grumpy Elantrian]

Is it possible to awaken aluminium? 

We know it's really difficult to awaken metal, so would aluminium be even harder to awake as it is essentially 'dead' and devoid of investiture. Is it perhaps even impossible to awaken aluminium for that same fact?

Or is aluminium instead more willing to awaken as if it craves investiture?

Thanks in advance for your input. 

[Scion of the Mists]

It is not possible to Awaken aluminum because it is "inert" and resists all magical attempts to change it:

On Nalthis, can aluminum prevent somebody from Returning? So if you kill somebody with aluminum and leave the weapon in them?

Brandon Sanderson

I don't think that's going to be enough. I think that…

Argent

Different way then?

Brandon Sanderson

Yeah there are totally ways. I don’t think that that’s going to be enough. There's a difference between being inert and blocking Investiture, and actually sucking out Investiture. If you stuck Nightblood inside of a corpse; there are certain things… if you had a larkin or whatever sitting there that ingests the Investiture as it was coming in, that would prevent [Returning]. I think with aluminum you would just have somebody that comes alive with a wound, so maybe... But I think it would just heal around [the aluminum] and you'd just have a spike in you, kind of like Hemalurgy—but not like Hemalurgy. It's inert, but you know what I mean.

Argent

Which suggests you can't actually Awaken aluminum.

Brandon Sanderson

No. It's not going to hold a charge.

Kurkistan

I assume you can't Forge it, either.

Brandon Sanderson

No. In fact the unForgable metal-

Argent

Ralkalest?

Brandon Sanderson

There's an unForgeable metal mentioned.

Kurkistan

Could we call it aluminum if we wanted to?

Brandon Sanderson

Let's just say that aluminum through most cultures was considered a mythological metal, and when people could actually find some, they considered it more valuable than gold, in our culture. So just sayin'...
