I've never seen new aluminium cases. If you mean once fired cases, most people toss them. I never have, and hopefully never will need to reload aluminium cases.
And no, aluminium does not work just like brass. Now if you have nickel coated brass, that's different.

I'm not sure what you mean by "the new" aluminum cases. I've loaded aluminum cases in .38 and .45 ACP. I didn't treat them any differently than brass. I use the seat/crimp die on .38 special for a light roll crimp. They shot just fine. This was mostly an experiment and I wouldn't intermix cases.
When I first bought my .44 Spl Bulldog, the only cases I could find to try it out at first were Blazers loaded with Gold Dots. I didn't want to shoot self defense loads just to try out the gun, so I pulled the bullets and reloaded them with lead ones I had on hand. Worked fine, but the aluminium sprung back from the crimp a bit more than brass, not much, but just noticeable. I didn't recrimp them and they worked fine.
Also didn't try to reload them for two reasons. First, they were berdan primed. And second, I met a guy at the range who had sold his .44 and sold me all of his stuff for it.

I have reloaded aluminum on a whim. They reloaded fine. Crimping was not a problem. As Cowboy_Dan said, a little spring back on the crimp.
I have reloaded .38 special and .45 acp aluminum cases. I only used the ones with the boxer primers. The .45 cases developed neck splits around the fifth reloading.
They were fired in a revolver. The .38s I will probably toss after the first reloading. I didn't notice anything different on the crimping. I only did it because some have said it couldn't be done....

CCI says they are not reloadable. Aluminum work hardens much faster than brass. You may get one reload out of them but you are very likely looking at case failure after that. Case failures can damage your firearm and injure you severely. It's really not worth the risk.

there is a place selling NEW aluminum 44 mag cases, primed. Hence the question about crimping new alum cases.

It's only hubris if I'm wrong.
These have had their bullets pulled and powder dumped, they aren't really "new", just unfired. That said, if I was gonna mess with them I'd give them a firm roll crimp into a crimping groove. If it relaxed some there should still be some crimp left.
