7075 uye 7050 ese ari maviri akareba-simba aruminiyamu alloys anowanzo shandiswa mumhepo uye zvimwe zvinoda maapplication. Nepo vachigovana zvimwe zvakafanana, ivo vanewo misiyano inoshamisa:
Composition
7075 aluminium alloyine kunyanya aluminium, zingi, mhangura, magnesium, uye zvisaririra zvechromium. Iyo dzimwe nguva inodaidzwa senge ndege-giredhi alloy.

7050 aluminium alloyzvakare ine aruminiyamu, zingi, mhangura, uye magnesium, asi kazhinji ine yakakwira zinc yemukati kana ichienzaniswa ne7075.

Simba
7075 inozivikanwa nekuda kwesimba rayo rakasiyana, ichiita kuti ive imwe yakasimba kwazvo aruminiyamu alloys iripo. Iyo ine yakakwira yekupedzisira tensile simba uye goho simba zvichienzaniswa ne7050.
7050 inopa simba rakanakisa zvakare, asi kazhinji ine zvishoma yakaderera simba zvivakwa zvichienzaniswa ne7075.
Corrosion Resistance
Ose ari maviri alloys ane good corrosion resistance, asi 7050 inogona kunge iine zvishoma zvirinani kuramba kustresser corrosion cracking zvichienzaniswa ne7075 nekuda kwekukwira kwayo zinc.
Kuneta Kuramba
7050 inowanzo ratidza kuramba kuneta kana ichienzaniswa ne7075, ichiita kuti ive yakakodzera kune maapplication uko cyclic kurodha kana kudzokororwa kushushikana kunetseka.
Weldability
7050 ine weldability iri nani kana ichienzaniswa ne 7075. Nepo ese ari maviri alloys anogona kugadzirwa, 7050 kazhinji isinganyanyi kutsemuka panguva yewelding process.
Applications
7075 inowanzoshandiswa muzvimiro zvendege, mabhasikoro epamusoro-soro, pfuti, uye zvimwe zvinoshandiswa uko kusimba kwehuremu hwehuremu uye kuoma kwakakosha.
7050 inoshandiswawo mukushandiswa kwemuchadenga, kunyanya munzvimbo dzinodiwa simba rakawanda, kumira kuneta kwakanaka, uye kuramba kwecorrosion, senge ndege fuselage mafuremu uye bulkheads.
Machinability
Ose ari maviri alloys anogona kugadzirwa, asi nekuda kwesimba rawo rakakwirira, anogona kupa matambudziko mukugadzira. Nekudaro, 7050 inogona kunge iri nyore kuita muchina kana ichienzaniswa ne7075.
