Aluminum 'nanocomposite'?
Meaning, full of 'floobie dust'?
I couldn't tell; their website is full of macromedia.

Actual mill certifications are frequently higher than specified minimums (i.e., MMPDS) but double tensile strength is hard to believe. Along with beter machiability, fabulous investment opprtunity, etc.
Small projects are the way to go, maybe holders for dilithium crystals. But remember the trouble Boeing had with 2524 for detail parts on overhead bins; the stuff could not be drilled (actually drills easily, but the random chipping and cracking were hardly desirable).
If the stuff meets an AMS-QQ, then wonderful. Otherwise it will be a while before it's seen on an aircraft.

The tensile strength comparison on Aluminastic.com website is misleading at best:
6061 "New Aluminum:" 41000 psi
6061 (unspecified temper): 18000 psi
The 18000 psi matches the UTS of annealed 6061 or the YS of 6061-T4. Hello? Doesn't almost everyone use 6061-T6 of UTS of 45000 psi in engineering applications?
Despite the hype on Aluminastic.com , Discontinuously Reinforced Aluminum (DRA) is a product whose time has come. First uses were in fighter jets and satellites, but as methods for incorporating particles into the aluminum casting process have improved and prices have decreased and knowledge increased, it is being used to replace both expensive fiber-reinforced composites as well as commonplace items such as cast iron brake drums. A good into to all types of aluminum matrix composites:
For more information, including use of flyash in aluminum matrix composites (aka full of 'floobie dust'), I recommend books and papers by Professor Pradeep K. Rohatgi:
