Mechanical Properties los ntawm Temper
7075-O Aluminium Ntawv
Nyob rau hauv annealed (O) temper, 7075 txhuas ntawv muaj lub zog tensile siab tshaj plaws ntawm kwv yees li.280 MPa (40,000 psi)thiab yield zog ntawm txog140 MPa (21,000 psi). Elongation feem ntau yog nyob ntawm9% mus rau 10%. Hauv qhov xwm txheej no, cov khoom siv muaj kev tiv thaiv corrosion zoo thiab lub zog nruab nrab.
7075-T6 Aluminium Ntawv
Hauv T6 temper, 7075 txhuas ntawv ua tiav lub zog tensile kawg ntawm510-540 MPa (74,000-78,000 psi)thiab muaj zog yield430-480 MPa (63,000-69,000 psi), nrog elongation ntawm5% thiab 11%.
Tus mob T6 tau txais los ntawm kev kho cua sov, quenching, thiab kev laus dag nyob ib puag ncig120℃rau 24 teev, uas ua rau lub zog siab tshaj plaws vim yog qhov ua tau zoo dispersed η thiab η′ precipitates.
7075-T651 Aluminium Ntawv
7075-T651 txhuas ntawv muaj ntau dua kev ua tau zoo, nrog rau qhov kawg tensile zog mus txog570 MPa (83,000 psi)thiab lub zog tawm los ntawm kwv yees li500 MPa (73,000 psi). Elongation ranges los ntawm3% mus rau 9%, nyob ntawm thickness. T651 npau taws suav nrog kev ntxhov siab los ntawm kev ncab tom qab kev kho cua sov.
7075-T7 / T73 Aluminium Sheet
T7 (los yog T73) npau taws ua tiav los ntawm dhau - laus. Nws muab lub zog qis dua me ntsis - ncig505 MPa tensile zog-tab sis tseem txhim khu kev tiv thaiv kev ntxhov siab corrosion cracking. Qhov npau taws no nta coarser η precipitates concentrated raws lis ciam teb, ua rau nws haum rau corrosion-sensitive aerospace daim ntaub ntawv.
7075-RRA Aluminium Ntawv
Covretrogression thiab re-aging (RRA)temper yog ib tug multi-theem kev kho cua sov uas ib ntus dhau- muaj hnub nyoog T6 cov ntaub ntawv thiab ces re- muaj hnub nyoog nws. Cov txheej txheem no rov ua kom lub zog ze rau T6 qib thaum txhim kho kev ntxhov siab corrosion.
Qhov sib txawv ntawm T651 thiab T7351 Tempers
T651: Tshuaj kho cua sov-kho, kev ntxhov siab-relieved los ntawm stretching, thiab artificially hnub nyoog rau siab tshaj plaws lub zog.
T7351: Tshuaj kho cua sov-kho, kev ntxhov siab-relieved, thiab tshaj- laus. Nws muajqis zog tshaj T651tab sisho txhim kho corrosion kuj, ua rau nws haum rau hnyav kev pab cuam ib puag ncig.
Daim ntawv thov ntawm 7075 Aluminium Sheet
Raws li ib qho ntawm feem ntau tus neeg sawv cev super- nyuaj alloys nyob rau hauv 7000 series, 7075 txhuas ntawv yog dav siv nyob rau hauvaerospace thiab siab - kev siv cov qauv kev nyuab siab, suav nrog:
Aircraft structural Cheebtsam
Wing panels, stringers, thiab thav ntawv
Siab -lub zog aviation qhov chaw
Lwm daim ntawv thov yuav tsum muaj lub zog tshwj xeeb thiab qaug zog ua haujlwm
GNEE muab siab -zoo 7075 txhuas ntawvrau aerospace, tooling, thiab advanced manufacturing industries, kom ntseeg tau zoo ib yam, muaj ntawv pov thawj zoo, thiab txhim khu kev qha xa.
