7A09 Aluminium Alloy
7A09 aluminium alloy yog lub zog muaj zog alloy. Lub plasticity nyob rau hauv lub annealed thiab cia li quenched lub xeev yog me ntsis qis dua li ntawm 2Y12 nyob rau hauv tib lub xeev thiab me ntsis zoo dua li ntawm 7A04. 7A09 aluminium alloy tau txo qis plasticity tom qab quenching thiab dag dag. 7A09 aluminium alloy muaj me ntsis zoo li qub kev qaug zog, tsis muaj kev cuam tshuam, thiab kev ntxhov siab corrosion ua tau zoo dua li 7A04 hauv daim ntawv, thiab lub bar yog piv rau 7A04.
Nws yog tus cwj pwm los ntawm cov yas zoo tom qab cov khoom siv kho mob, tshwj xeeb tshaj yog kev kho cua sov ua kom muaj zog ntxiv, lub zog siab qis dua 150 degree thiab tshwj xeeb yog qhov zoo ntawm qhov kub thiab txias; welding tsis zoo; qhov nyiam ntawm kev ntxhov siab corrosion tawg; yuav tsum tau siv los ntawm clad aluminium los yog lwm yam kev tiv thaiv kev kho mob. Ob-theem kev laus tuaj yeem txhim kho cov alloy lub peev xwm los tiv thaiv kev ntxhov siab corrosion cracking. Lub plasticity nyob rau hauv lub xeev annealed thiab freshly quenched yog me ntsis qis dua li ntawm 2A12 nyob rau hauv tib lub xeev thiab me ntsis zoo dua li ntawm 7A04, qhov zoo li qub qaug zog ntawm lub phaj. Notch-rhiab heev, kev ntxhov siab corrosion ua haujlwm zoo dua 7A04.

Daim ntawv thov ntawm 7A09 Aluminium Alloy
7A09 feem ntau yog siv rau hauv kev tsim cov qauv dav hlau thiab lwm yam kev ua haujlwm siab uas yuav tsum tau muaj zog thiab corrosion kuj, xws li cov phab ntsa sab sauv thiab sab qis thiab cov trusses. Nws muaj cov yas zoo tom qab kev kho mob, kev kho cua sov zoo ntxiv zog, lub zog zoo hauv qab 150 degrees, tshwj xeeb tshaj yog qhov kub thiab txias zog, tsis zoo vuam kev ua tau zoo, thiab muaj lub siab nyiam corrosion corrosion. Kuj tseem siv dav hauv kev ua pwm, cov cuab yeej siv tshuab, khoom siv, kev lag luam aerospace, tshuab moulding (lub raj mis) pwm, ultrasonic yas vuam pwm, golf taub hau, khau pwm, ntawv yas pwm, ua npuas ncauj molding pwm, waxing pwm, khoom siv tshuab, siv. los ua high-end aluminium alloy tsheb kauj vab ncej.
