3A21 Aluminium Alloy
3A21 aluminium alloy yog ib qho Al-Mn alloy, uas yog cov khoom siv dav siv los tiv thaiv xeb. Lub zog ntawm cov hlau no tsis siab (me ntsis siab dua li cov khoom siv ntshiab aluminium) thiab tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov. Yog li ntawd, txoj kev ua haujlwm txias yog siv los txhim kho nws cov khoom siv kho tshuab. Nws muaj plasticity siab nyob rau hauv lub xeev annealed, zoo plasticity nyob rau hauv semi-txias ua hauj lwm hardening, tsis tshua muaj plasticity nyob rau hauv txias ua hauj lwm hardening, zoo corrosion kuj, zoo weldability, thiab tsis zoo machinability.

Nta ntawm 3A21 Aluminium Alloy
- Tsis muaj zog heev
- Zoo corrosion kuj
- Zoo weldability
-Machinability tsis zoo
- High plasticity nyob rau hauv lub xeev annealed, zoo plasticity nyob rau hauv semi-txias ua hauj lwm hardening, tsawg plasticity nyob rau hauv txias ua hauj lwm hardening
Daim ntawv thov ntawm 3A21 Aluminium Alloy
Nws yog tsuas yog siv rau vuam qhov chaw uas yuav tsum tau siab plasticity thiab zoo weldability, xws li aerospace, tub rog khoom, cuab yeej fixtures, tsheb, tsheb thauj mus los, ua propellant cia tso tsheb hlau luam, vuam structural cabin skins, kawg thav ntawv, brackets, thiab lwm yam thiab cov kav dej ua haujlwm. hauv corrosive media, thiab lwm yam.
