Aloy 7075 aluminium ndi gawo labwino kwambiri mu 7xxx mndandanda wazomwe zili mkati mwamphamvu kwambiri zomwe zikupezeka. Zinc ndiye chinthu chokhalitsa chachikulu chomwe chimapereka mphamvu ofanana ndi zitsulo. Kukwiya t651 kumakhala ndi mphamvu yabwino, yolimbana ndi magetsi, kukana magetsi ndi kupindika. Alloy 7075 mu Serper T7x51 ali ndi nkhawa kwambiri ndikukana 2xxx chiwonetsero chazovuta kwambiri.

7075 Aluminiyamu alloy ndi amodzi mwa aluminiyamu wamphamvu kwambiri wa aluminiyamu wopezeka, ndikupangitsa kukhala wofunika kwambiri. Mphamvu yake yayitali imakhala ndi mphamvu (> 500 MPA) ndipo kachulukidwe kake kakang'ono kakupangitsa kuti zinthu zizigwiritsidwa ntchito ngati gawo la ndege kapena mbali zomwe zimasokonekera. Ngakhale kuti sizachilendo chocheperako kuposa ma entros (monga 5083 aluminiyamu sloy, omwe amakhudzidwa kwambiri ndi kututa), mphamvu zake kuposa kulungamitsa ma dolides.

Kutsutsa kwamphamvu kwambiri kwa T.3551 Kuchepetsa t6 ndi t651 kumakhala ndi makina abwino. Alloy 7075 amagwiritsidwa ntchito kwambiri ndi ndege ndi mafakitale a ndege chifukwa cha mphamvu zake zazikulu.
