Ziziphi iimpawu ze-7055 aluminium alloy? Isetyenziswa phi ngokukhethekileyo?

I-brand ye-7055 yaveliswa yi-Alcoa kwiminyaka ye-1980 kwaye ngoku iyona nto iphambili yorhwebo oluphezulu lwe-aluminium alloy. Ngokusungulwa kwe-7055, i-Alcoa nayo yavelisa inkqubo yonyango lokushisa kwe-T77 ngexesha elifanayo.

Uphando ngesi sixhobo e-China mhlawumbi lwaqala phakathi ukuya ngasekupheleni kweminyaka yee-1990. Ukusetyenziswa kwefektri yesi sixhobo kunqabile, kwaye isetyenziswa ngokubanzi kwimveliso yeenqwelomoya, njengesikhumba sephiko eliphezulu, umsila othe tyaba, i-dragon skeleton, njalo njalo kwi-B777 kunye ne-A380 Airbus.

Esi sixhobo ngokuqhelekileyo asifumaneki kwiimarike, ngokungafaniyo ne-7075. Icandelo eliphambili le-7055 yi-aluminium, i-manganese, i-zinc, i-magnesium, kunye nobhedu, okuyisona sizathu esibalulekileyo sokuhlukana komsebenzi phakathi kwezi zibini. Ukonyuka kwento yemanganese kuthetha ukuba i-7055 inokumelana ne-corrosion, iplastiki, kunye ne-weldability xa kuthelekiswa ne-7075.

Kuyafaneleka ukukhankanya ukuba ulusu oluphezulu kunye ne-truss ephezulu yephiko le-C919 zombini ziyi-7055.
