Why do they claim that the hull is somehow BETTER becuase it is made of all iron instead of an alloy? It is common knowledge that alloys are better than pure iron in most ways. Is there some discernable reason they would say that?
Because the people who made this movie are not scientists. Most of the people who watch this movie wouldn't realize that alloys are superior to non-alloyed materials, and the people who do typically wouldn't care, because they're watching a giant robot movie and therefore presumably know better than to expect realism.
I remember when Shoe posted about this a while ago.
We decided that it was either a tribute to The Iron Giant.
Or was possibly made of a lesser alloy that had less that 50% iron or something, which would make a 100% iron hull a good thing. Maybe it just had a shitload of impurities that created uneven hull-strength/density.
Nobody's figured that out yet? That's an old Japanese thing that "pure" is better than "not pure."
From Wikipedia: Popularity of the pure-blood eugenics theory came from a homegrown racial purity or monoculture national belief that has been part of Japanese society since ancient times. The local movement was however less focused on modern scientific ideals and more on the "outside person" vs the "native or inside person" and blood purity. Later legal measures were supported by certain politicians and movements that sought to increase the number of healthy pure Japanese....
So in the movie they put in this silly pure iron thing to appeal to Japanese audiences.
except they will be britte to the point that a house made of that stuff could be demolished by one guy without any bulldozers or any other vehicles
and your possibly mixing up "steel-glass alloy" with metallic glass which is supercooled liquid metal not metal and glass together and is it even possible for a natural glass to be alloy compatible with steel
Maybe it was because it was cheaper. Also, it doesn't really matter what the jaegers hulls were made of, IRL, they would have been crushed like a tin can at anywhere near the depth of challenger deep, due to the structure of the jaeger's hulls. If they were in giant hamster balls it would have worked.

Actually you can have metal glass that's not brittle like glass. From popsci.com: Materials scientists in California have made a special metallic glass with a strength and toughness greater than any known material, using a recipe that could yield a new method for materials fabrication.
The glass, a microalloy made of palladium, has a chemical structure that counteracts the inherent brittleness of glass but maintains its strength. It's not very dense and it is more lightweight than steel, with comparable heft to an aluminum or titanium alloy.
"It has probably the best combination of strength and toughness that has ever been achieved," said Robert O. Ritchie, a materials scientist at Lawrence Berkeley National Laboratory who is one of the authors of a paper describing the new glass. "It's not the strongest material ever made, but it's certainly one of the best with a combination of strength and toughness."
Actually the whole "solid iron" incedent was a miscommunications issue. Mr. Choi was unfortunately busy serenading his begal quietly when we informed him of Gipsy Danger's restoration.
I don't know why but despite many attempts to give him the correct information, he still insists Gipsy Danger has been upgraded to a solid iron hull. I've put it down to lack of engineering intelligence.
Sorry for the awful necro, but I may have three possible explanations for the "iron". Bear in mind this is all pure conjecture, but I wanted to throw in my two cents.
The first explanation is that it's simply rule of cool. However, this is not in any way logical, rational or reasonable, nor is it anything like what intelligent people would consider, so we should discard it immediately.
The other two explanations are:
"Iron" was simply used as a term for some sort of bullshit space magic material. Possibly the "no alloys" was referring to a lack of metal alloys which are known to show up as impurities in this material. Perhaps they perfected the production process (ie worked out how to make it with no impurities) just for Gipsy, to make it properly special (this would be symbolic of Gipsy's special role in the plot).
European folklore is canon so iron is just special. However given that PR is science fiction and not fantasy, I'm inclined to discard this.
I think there is a possible reason why Iron was chosen over steel for Gipsy's hull. (Probably wrong in a lot of areas but meh)
While steel is much stronger than iron, iron is more malleable and less stiff than steel.
If a Kaiju struck against Gipsy if she was made of steel, the plates would recieve too much stress and would eventually snap and reveal the insides.
On the other hand, if a Kaiju struck Gipsy if she was made of iron, the plates would bend under the impact without snapping and revealing the insides.
Also, if you were to repair Gipsy, the steel plates would need to be replaced and welded back, while iron only needs to be hammered back into shape.
Or maybe via the power of fuck logic magic
Alloy or Non pure Iron Armour=Paper Mache
Iron Armour=Plot Armour
Now that i think about it, Pure Iron being Plot material is more plausible since all the other Jaegers were made of alloys and non pure iron stuff and they all didn't seal the breach while a Pure Iron made Gipsy did.
Gipsy wasn't the only one whose hull was "pure". Crimson Typhoon was said to be pure titanium with no alloys.
Honestly, though, I'd say that Gipsy's success where other Jaegers failed had more to do with its armament, pilots, and unexpected appearance than with the material its armor was made of (or the fact that it happened to be the "main" Jaeger, if we want to go the narrative route).
