Zithini iimpawu ezingama-60555 alloy? Isetyenziswa phi ngokuthe ngqo?

I-7055 iBrand yaveliswa yiAlcoa ngeminyaka yoo-1980 kwaye okwangoku yeyeyona nto iphambili kwezona suminium. Ngokwaziswa kwe-7055, i-Alcoa ikwaphuhlise inkqubo yonyango lobushushu ye-T77 ngaxeshanye.

Uphando malunga nolu phawu e-China kusenokwenzeka ukuba lwaqala phakathi kwiminyaka yo-1990. Ukusetyenziswa kwezommiselo zale nto kunqabile, kwaye isetyenziswa ngokubanzi kwimveliso yeenqwelomoya, enjengolusu oluthe tye, umsila othe tyaba, inamba inamba, njalo njalo kwi-A380 Airbus.

Esi sixhobo asifumaneki emarikeni, singafani ne-7075. Eyona nto iphambili eyi-7055 yi-aluminium, i-manganese, i-zinc, i-wincle, esona sizathu siphambili sokusebenza phakathi kwezi zimbini. Ukunyuka kwento yeManganese kuthetha ukuba i-7055 inomelele ngakumbi, iprintaty, iplastiki, kunye nokufakelwa kwempikiswano xa kuthelekiswa ne-7075.

Kufanelekile ukukhankanya ukuba ulusu oluphezulu kunye ne-truss ephezulu ye-C919 iphiko lowama-7055.
