Yiziphi izici ze-7055 aluminium alloy? Isetshenziswa kuphi ngokuqondile?

Uhlobo lwe-7055 lwakhiqizwa yi-Alcoa ngeminyaka yawo-1980 futhi njengamanje luyingxube ye-aluminium enamandla kakhulu yokuhweba. Ngokusungulwa kwe-7055, i-Alcoa iphinde yathuthukisa inqubo yokwelapha ukushisa kwe-T77 ngesikhathi esifanayo.

Ucwaningo ngale nto e-China cishe lwaqala maphakathi nawo-1990 ngasekupheleni. Ukusetshenziswa kwalezi zinto ezimbonini kuyivelakancane uma kuqhathaniswa, futhi ngokuvamile kusetshenziselwa ukukhiqiza izindiza, njengesikhumba esingaphezulu kwephiko, umsila ovundlile, uhlaka lwamathambo kadrako, njalo njalo ku-B777 ne-A380 Airbus.

Lokhu okuqukethwe ngokuvamile akutholakali emakethe, ngokungafani ne-7075. Ingxenye eyinhloko ye-7055 i-aluminium, i-manganese, i-zinc, i-magnesium, nethusi, okuyisizathu esiyinhloko somehluko wokusebenza phakathi kokubili. Ukwanda kwe-manganese element kusho ukuthi i-7055 inokumelana nokugqwala okuqinile, ipulasitiki, kanye nokushisela uma kuqhathaniswa no-7075.

Kuhle ukusho ukuthi isikhumba esingaphezulu kanye ne-truss engaphezulu yephiko le-C919 zombili ziyi-7055.
