AFAIK toughness was an issue with hexagonal cristalline aluminium. The other was cost.

As far as I am aware, they are not the same (but I could well be wrong). I am no material expert but I believe one is the lattice in 3D and the other lattice structure is not quite as intricate so it's heavier.
I don't know. Thyssen Krupp would have those details.robertbb wrote: ↑Thu Jan 17, 2019 9:26 pmHow easy is it to make tubes from, and to weld?
Saying the material is an aluminum alloy called “superlight” effectively makes it un-googleable. There’s some vague detail about crystal structure and some outlandish claims about material properties, but these don’t make this mystery material any easier to search for.hambini wrote: ↑Thu Jan 10, 2019 7:45 amOne of the developments in material technology is a material called superlight. It's an Aluminium alloy with hexagonal crystalline construction. This is about 50% lighter than normal aluminium and almost all of the tensile strength. I have made a couple of these for test purposes for some of the pro cycling teams I supply.
2lo8 asked a simple, direct question, and Hambini managed to respond without actually answering. Instead, he did some technical handwaving about crystal lattice structures and disavowed expertise in materials. OK, he doesn’t have to be a materials scientist. But surely he can point us to a site/paper/press release that would help sate our curiosity. But no. Why not just post a link as requested?
But wait! Hambini threw us a bone and implied that thyssenkrupp (that’s how they write it) is the source of this very exciting material and will “have those details.” Woohoo! They’re a giant conglomerate that does quite a bit of aluminum smelting and materials development. Surely they’ve issued a press release about this very promising new material. We’ll certainly track it down now!
That resonates precisely because Hambini has so far refused to provide any proof that “lightweight aluminum” is real. I think it would be wrong to attribute any one of these things to malice. But when you consider these points and others in context, a pattern seems to emerge, and it’s a somewhat disturbing one.FLO Cycling wrote:What's odd, [sic] is Hambini continues to insist we sent the letter but refuses to provide any proof the letter is real.
You do realize this is the internet, and this particular web page collects opinions of characters, some fictional, some factually present in this universe and some somewhere in between? And you are seriously concerned about statements presented in this thread?youngs_modulus wrote:But this raises a troubling question: if the source of this wonder-material is in fact Hambini’s imagination, what else is he making up? I’m not suggesting that he’s fabricated is wheel drag results or anything like that; Hambini’s pretty opaque about the details we’d need to reach a conclusion one way or the other.
More likely that it's just been a few paragraphs in one of the internal magazines/blogs at work. So replace "cagey" with "doesn't actually work with it, so doesn't know much more than already posted". And "the company isn't posting much until they've got the patents lined up".youngs_modulus wrote: ↑Fri Jan 18, 2019 3:55 amSomething here doesn’t pass the sniff test.

It is not my duty to go searching the internet to find out details about materials so I can appease people on weightweenies. The entire basis of your argument is because you find a published paper about material X on the internet that it must not exist. Further, As you claim to work in the Aerospace industry, I would say you were somewhat naive and ignorant.youngs_modulus wrote: ↑Fri Jan 18, 2019 3:55 amLot's of stuff removed to try not to litter the thread.
