Kwihlabathi elikhawulezayo lezinto ezikhaphukhaphu, zimbalwa iingxoxo ezibangela ukuba iinjineli zisebenze kakhulu njenge-aluminium engu-6061 xa kuthelekiswa ne-aluminium engu-7075. Ezi ngxube zimbini zilawula iziphelo ezichaseneyo ze-spectrum yokusebenza: i-6061 yeyona ithembekileyo efumaneka kuyo yonke into ukusuka kwizakhelo zeebhayisekile ukuya kwizakhiwo zeemoto, ngelixa i-7075 yeyona ntshatsheli inamandla aphezulu kakhulu enika amandla amaphiko eenqwelo moya kunye nezixhobo zemidlalo eziphezulu. Njengoko imfuno ye-aluminium isanda ngo-2026—ngenxa yokukhanya kweqonga le-EV, ukwanda kweedrone, kunye nokwakhiwa okuzinzileyo—ukukhetha phakathi kwazo kunokwenza okanye kuphule ixabiso loyilo, ukuqina, kunye nokusebenza.
Ukusetyenziswa kwe-aluminium kwihlabathi jikelele kuqikelelwa ukuba kuza kudlula kwiitoni ezingama-78 ezigidi kulo nyaka, aphoI-6xxx kunye ne-7xxxAmanqanaba ochungechunge akhokela intlawulo kwizicelo zesakhiwo. Amaxabiso e-6061 kunye ne-7075 ahlala ephakanyisiwe, apho i-7075 ibiza iprimiyamu engama-20–40% ngenxa yomxholo wayo we-zinc kunye nobunzima bokucubungula. Nantsi indlela ecacileyo yokuchaza indlela ezihlanganiswa ngayo, ngokusekelwe kwiipropati zehlabathi lokwenyani, usetyenziso, amandla, ubuthathaka, kunye nokuba enye isebenza ngcono kangakanani na kunenye.

- Ukuguguleka okuphantsi - kunokuba buthathaka xa kuthe kwabethwa
Izicelo zeHlabathi lokwenyani: Apho nganye ikhanya khona
I-6061 ilawula ngaphakathi:
- Itshasi yeemoto, iitreyi zebhetri ze-EV, kunye neefreyimu zesakhiwo (iimfuno zokuwelda ezikhaphukhaphu)
- Izinto ezidityanisiweyo zokwakha, iifreyimu zeefestile, kunye ne-scaffolding
- Izinto zaselwandle, iifreyimu zeebhayisekile, kunye nezinto zemidlalo
- Izinki zobushushu kunye nokuveliswa ngokubanzi apho ixabiso kunye nokugqwala kubalulekile khona
I-7075 Ikhokela:
- Izinto zokwakha ze-aerospace (ii-wing spars, ii-fuselage frames)
- Izixhobo zokukhwela amatye ezisebenza kakuhle, izixhobo zokwamkela imipu, kunye nezixhobo zobuchule
- Amavili eemoto, iindawo zokumiswa, kunye neengalo zedrone
- Iipleyiti zezixhobo kunye neenkuni ezifuna ukuqina okuphezulu
Kuyilo lwe-EV, umzekelo, abavelisi abaninzi badibanisa zombini ezi zinto: i-6061 yezakhiwo zomzimba ezidityaniswayo kunye ne-7075 yeendlela zomthwalo obalulekileyo ezifana nee-suspension mounts.
Iimeko zokuthelekisa ubuso ngobuso
- Iimfuno zamandlaUkuba udinga i-tensile engaphezulu kwe-500 MPa, i-7075 iyaphumelela. Kwi-300–400 MPa, i-6061 inika i-80% yokusebenza nge-60% yexabiso.
- Ukuvezwa Kokugqwala: 6061 lukhetho olucacileyo ngaphandle okanye kwiindawo ezifumileyo. 7075 ifuna iileya ze-Alclad okanye iipeyinti ukuze zihambelane.
- Ubulula bokubumba: 6061 ixolela ngakumbi ekudibaniseni nasekubumbeni—ilungele iiprototypes okanye imveliso ephakathi.
- Uxinzelelo Oluphezulu Olubaluleke Kakhulu: Uxinano oluphezulu lwe-7075 luncitshiswa ziindawo ezincinci ezinokwenzeka ngenxa yamandla aphezulu.
- Ubuthathaka beendlekoI-6061 inika ixabiso elingcono kwiintlobo ezininzi zezicelo zorhwebo; i-7075 iqinisekisa ixabiso layo eliphezulu kwi-aerospace okanye ukhuselo apho ukungaphumeleli kungelulo ukhetho.
Iindlela zeMarike zika-2026 ezichaphazela ukhetho
Ukunyuka komthamo ophinda usetyenziswe (ngoku ongaphezulu kwama-40% kwiifektri ezininzi) kunciphisa umsantsa wamaxabiso, ngelixa uphuhliso olutsha lonyango lobushushu luphucula ukumelana nokugqwala kwama-7075 (khangela ii-tempers ezintsha ze-T73/T77). Okwangoku, ii-variants ezingama-6061 ezine-scandium eyongezelelweyo zikhulisa amandla kwizicelo ze-EV. Imithetho yozinzo eYurophu naseCalifornia ityhala i-clad 7075 kwaye i-anodized 6061 ukuze isebenze ixesha elide.
Ingongoma ephambili: Akukho mntu uphumeleleyo kwihlabathi liphela—i-6061 liqhawe eliguquguqukayo lemihla ngemihla, ngelixa i-7075 inamandla akhethekileyo. Tshatisa i-alloy nezinto eziza kuqala kuwe: uhlahlo lwabiwo-mali kunye nokuveliswa kwemveliso kuthanda i-6061; ukusebenza okuphezulu kuthanda i-7075.
