Ndeapi maitiro e7055 aluminium alloy? Inoshandiswa papi chaizvo?

Chiratidzo che7055 chakagadzirwa neAlcoa mumakore ekuma1980 uye pari zvino ndiyo yakanyanya kutengeserana yepamusoro-simba realuminium alloy. Nekutanga kwe7055, Alcoa yakagadzirawo nzira yekupisa yeT77 panguva imwe chete.

Tsvagiridzo pamusoro pechinhu ichi muChina pamwe yakatanga pakati pekupedzisira 1990s. Iko kushandiswa kwemaindasitiri kwechinhu ichi hachiwanzo shomeka, uye chinowanzoshandiswa mukugadzira ndege, senge ganda rebapiro repamusoro, muswe wakatwasuka, shato skeleton, zvichingodaro paB777 uye A380 Airbus.

Ichi chinyorwa hachiwanzo kuwanikwa mumusika, kusiyana ne7075. Chikamu chikuru che 7055 ialuminium, manganese, zinc, magnesium, uye mhangura, iyo ndiyowo chikonzero chikuru chekusiyana kwekuita pakati pezviviri. Kuwedzera kwe manganese element kunoreva kuti 7055 ine yakasimba corrosion resistance, plasticity, uye weldability zvichienzaniswa ne7075.

Zvakakodzera kutaura kuti ganda repamusoro uye repamusoro truss yeC919 bapiro zvese 7055.
