(Gawo 1: 2-mndandanda wa aluminiyamu aloyi)

2-series aluminium alloy imatengedwa kuti ndiyo yoyamba komanso yogwiritsidwa ntchito kwambiri pamayendedwe amtundu wa aluminiyamu.

Bokosi la crank la Wright Brothers 'Flight 1 mu 1903 linapangidwa ndi aluminium copper alloy casting. Pambuyo pa 1906, ma aluminiyamu a 2017, 2014, ndi 2024 adapangidwa motsatizana. Isanafike 1944, 2-series aluminium alloys inkawerengera zoposa 90% ya zinthu zotayidwa zomwe zimagwiritsidwa ntchito popanga ndege. Ngakhale pano, akadali amodzi mwa aloyi omwe amagwiritsidwa ntchito kwambiri muzamlengalenga.

Aloyi yomwe imagwiritsidwa ntchito kwambiri pa ndege ndi 2024, yomwe idapangidwa ndi kampani ya aluminiyamu yaku America mu 1932. Pali ma alloys 8 omwe amagwiritsidwa ntchito kwambiri (mtundu wa 2024).

Pakupanga ndege zapagulu, kugwiritsa ntchito ukonde wa 2024 aluminiyamu alloy kumapitilira 30% yazomwe zimagwiritsidwa ntchito ndi aluminiyamu.
