Theory: Duralumin could enhance fabrials

[TheCollector]

This might not be an original thought, but I didn't see it anywhere, so, here goes:

On Scadrial, aluminum gets rid of all metals in a Mistborn. On Roshar, aluminum stops a paired fabrial from being connected briefly. On Scadrial, duralumin enhances a Mistborn's powers greatly. On Roshar, duralumin could be used to enhance a paired fabrial, such as the Fourth Bridge. I believe that if duralumin was used on, say, Fourth Bridge while it was flying, whenever the Shattered Plains gemstone moved a foot, the Fourth Bridge would move forward many times that, greatly enhancing the speed.

(Sorry if my Scadrial information isn't accurate, I haven't read all of the Mistborn books yet. I'm working on it)

EDIT:

I have more evidence to support my theory:

Quote

With a captured spren, you may begin designing a proper fabrial. It is a closely guarded secret of artifabrians that spren, when trapped, respond to different types of metals in different ways. A wire housing for the fabrial, called a “cage,” is essential to controlling the device.

The two metals of primary significance are zinc and brass, which allow you to control expression strength. Zinc wires touching the gemstone will cause the spren inside to more strongly manifest, while brass will cause the spren to withdraw and its power to dim.

A bronze cage can create a warning fabrial, alerting one to objects or entities nearby. Heliodors are being used for this currently, and there is some good reasoning for this—but other gemstones should be viable.

A pewter cage will cause the spren of your fabrial to express its attribute in force—a flamespren, for example, will create heat. We call these augmenters. They tend to use Stormlight more quickly than other fabrials.

An iron cage will create an attractor—a fabrial that draws specific elements to itself. A properly created smoke fabrial, for example, can gather the smoke of a fire and hold it close.

That's kind of long, so I will break it down a bit, and explain.

This is interesting, because in Allomancy, using zinc causes emotions to more strongly manifest, and using brass will cause emotions to withdraw.

This is a bit more of a stretch than the last one, but in Allomancy, bronze allows a person to see if someone is using Allomancy nearby. It is similar to a warning fabrial, though the fabrial is more general.

Pewter, in Allomancy, augments the phisical attributes of a person burning it, similar to the fabrial.

The iron cage is very similar to what happens when a person burns iron in Allomancy for it can pull on nearby sources of metal.

There are other metal cages mentioned, but they aren't as apparently similar as these five. However, I feel that this is plenty of evidence that duralumin would enhance a fabrial, maybe even not just paired fabrials. Perhaps if it was used on a heat fabrial, for example, it would make the fabrial give of many times more heat than it normaly would. Thoughts?

On Roshar, aluminum sucks stormlight away from the Radiant

That's Raysium not aluminium

and stops a paired fabrial from being connected briefly.

It's not a Fabrial effect anymore than Aluminium stopping emotional Allomancy is an Allomantic effect

I can't think of a way of that not being redundant with either Steel, Zinc or strengh multipliers, in Hemalurgy and Ferruchemy duralumin affect Connection so if Duralumin has any effect on Fabrials (which is far from sure, remember Roshar is 10 centric) it would probably have Connection effects. Maybe decreasing the decay of paired Fabrials would be possible?

I may be wrong, but I feel like somewhere in RoW Raboniel told Navani that Raysium was just what the Fused called aluminum

No, they call aluminium "Rahkalest", like the MaiPon people

I see. I must have mixed Raysium and Rahkalest in my head. Thank you for correcting me.

Uh, how would they do it mechanically? Have a switch to move the cage of the gemstone to another cage to activate the enhanced powers?

Because having it at ludicrous duralumin power will just waste stormlight.

This seems like a reasonable idea, although in non-paired fabrials it sounds like it would work very similar to pewter (unless I am misunderstanding).

I would propose alternative, in feruchemy duralumin stores connection, and in allomancy we could read the burst coming from greatly increased connection to Shard in the moment of burn. Hence I would propose that duralumin in fabrials could be used to increase effective range of conjoined fabrials by strengthening the connection between the halves of the gems, albeit at the cost of greater stormlight use potentially.
