More info re: Airliners edit
The article currently states:
"They are currently used in a few commercial jetliner airframes".
I request that more info be provided here. Which jetliners are currently using Al-Li? Thanks, Lester 23:53, 10 April 2008 (UTC)
solubility limit edit
The article currently states:
- Commercial Al-Li alloys contain up to 2.45% lithium...
- This effect works up to the solubility limit of lithium in aluminium...
So, what is the solubility limit of lithium in aluminum? Is 2.45 % the solubility limit of lithium in aluminum? Geo Swan (talk) 13:50, 14 May 2009 (UTC)
Lighter but bigger? edit
I'm surprised to see the Li atom is bigger than the Al atom. Al has more electrons and I'd expect a wider radius therefore. How does that work? Midgley (talk) 10:55, 14 August 2009 (UTC)
- See the atomic radius article for a periodic table of radii and a good explanation. --IanOsgood (talk) 21:15, 23 July 2010 (UTC)
Aplication as armor edit
Is any kind of Al-Li alloy used as an armor or to make a helmet?This site: [Key to metals] talks about this subject, but doesn't tells if Al-Li is being used ina commercial base.Agre22 (talk) 21:09, 20 October 2009 (UTC)agre22
Size of atoms ? lithium atom is larger than an aluminium one ? edit
the article says
"Strain hardening- The lithium atom is larger than an aluminium one"
really ? the lithium atom with 3 proton and 3 electrons on 2 shells is bigger than the aluminium atom with 13 protons and 13 electrons on 3 shells ? how is that even possible ? by redefining the definition of "largeness" for an atom ?

- Just FYI, the lithium atom is larger than the aluminum atom. See the atomic radius article IanOsgood linked to earler. 24.130.82.66 (talk) 18:09, 26 November 2011 (UTC)
Should note many have more copper than lithium by mass edit
Should note many (the 2000 series) have more copper than lithium by mass. Can we explain why they are called Al-Li alloys ? & Are they all less dense than pure Al as implied by intro ? - Rod57 (talk) 10:00, 22 March 2021 (UTC)
