I-7075 kunye ne-7050 zombini i-alloys ye-aluminiyam yamandla aphezulu aqhelekileyo asetyenziswa kwi-aerospace kunye nezinye izicelo ezifunwayo. Ngelixa babelana ngezinto ezifanayo, bakwanazo umahluko obonakalayo:

Ukuqamba

7075 aluminium ingxubevangeiqulethe ngokuyintloko i-aluminiyam, i-zinc, ubhedu, i-magnesium, kunye neempawu zechromium. Ngamanye amaxesha ibizwa ngokuba yi-alloy-grade alloy.

Ubume beMichiza WT(%)

0.4	0.5	1.2~2	2.1~2.9	0.3	0.18~0,28	5.1~5.6	0.2	0.05	Intsalela

7050 aluminium ingxubevangeikwaqulethe i-aluminiyam, i-zinc, ubhedu, kunye ne-magnesium, kodwa inomxholo ophezulu we-zinc xa kuthelekiswa ne-7075.

Amandla

I-7075 yaziwa ngamandla ayo akhethekileyo, nto leyo eyenza ukuba ibe yenye yezona zixhobo zinamandla ze-aluminiyam ezikhoyo. Inamandla okugqibela aphezulu kunye namandla esivuno xa kuthelekiswa ne-7050.

I-7050 inika amandla agqwesileyo ngokunjalo, kodwa ngokubanzi ineempawu zamandla asezantsi kancinci xa kuthelekiswa ne-7075.

Ukunyangwa kokuMhlwa

Zombini ii-alloys zinokuxhathisa okuhle kokutya, kodwa i-7050 inokuba nokuxhathisa ngcono kancinci kuxinzelelo lokuqhekeka kwe-corrosion xa kuthelekiswa ne-7075 ngenxa yomxholo wayo we-zinc ephezulu.

Ukudinwa Ukumelana

I-7050 ngokubanzi ibonisa ukuchasana kokukhathala okungcono xa kuthelekiswa ne-7075, okwenza ukuba ilungele izicelo apho ukulayisha i-cyclic okanye uxinzelelo oluphindaphindiweyo luyinkxalabo.

Ukuweldability

I-7050 ine-weldability engcono xa kuthelekiswa ne-7075. Nangona zombini i-alloys inokudityaniswa, i-7050 idla ngokuncinci ukukrazula ngexesha leenkqubo ze-welding.

Usetyenziso

I-7075 idla ngokusetyenziswa kwizakhiwo zenqwelomoya, iibhayisekile ezisebenza ngokuphezulu, imipu, kunye nezinye iinkqubo apho umlinganiselo wobunzima obuphezulu kunye nokuqina kubalulekile.

I-7050 ikwasetyenziswa kwizicelo ze-aerospace, ngakumbi kwiindawo apho amandla aphezulu, ukumelana nokudinwa okulungileyo, kunye nokumelana nomhlwa, okufana nefreyimu ye-fselage yenqwelomoya kunye ne-bulkheads.

Ubuchule

Zombini ii-alloys zingenziwa ngoomatshini, kodwa ngenxa yamandla abo aphezulu, zinokuzisa imingeni kumatshini. Nangona kunjalo, i-7050 inokuba lula kancinci kumatshini xa kuthelekiswa ne-7075.
