(Theem 1: 2-series aluminium alloy)

2-series aluminium alloy yog suav tias yog qhov ntxov tshaj plaws thiab feem ntau siv dav hlau aviation aluminium alloy.

Lub thawv crank ntawm Wright cov kwv tij 'Flight 1 hauv 1903 yog ua los ntawm txhuas tooj liab alloy casting. Tom qab xyoo 1906, aluminium alloys ntawm 2017, 2014, thiab 2024 tau tsim ua tiav. Ua ntej xyoo 1944, 2-series aluminium alloys suav nrog ntau dua 90% ntawm cov khoom siv txhuas siv hauv cov qauv dav hlau. Txawm tias tam sim no, nws tseem yog ib qho ntawm cov khoom siv dav tshaj plaws hauv cov khoom siv hauv aerospace.

Feem ntau siv alloys ntawm aircraft yog 2024, uas tau tsim los ntawm American aluminium lub tuam txhab nyob rau hauv 1932. Tseem muaj 8 feem ntau siv alloys (2024 hom).

Hauv kev tsim dav hlau dav hlau tam sim no, kev siv net ntawm 2024 aluminium alloy nyiaj ntau dua 30% ntawm tag nrho cov net siv ntawm txhuas.
