Cov raj txhuas yog cov khoom siv tau ntau yam thiab siv tau dav nrog ntau yam kev siv thoob plaws ntau yam lag luam. Cov raj no tau txais kev nyiam vim lawv qhov sib dua, tiv taus xeb, thiab muaj peev xwm yooj yim tsim thiab tshuab, ua rau lawv yog ib qho tseem ceeb hauv txhua yam los ntawm kev tsim kho aerospace mus rau cov khoom siv hauv tsev txhua hnub xws li rooj tog thiab khoom siv.
Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau cov raj txhuas nrov heev yog lawv qhov sib piv ntawm lub zog thiab qhov hnyav. Aluminium yog li ib feem peb ntawm qhov hnyav ntawm cov hlau, tab sis nws muaj lub zog zoo kawg nkaus uas tso cai rau nws los tiv taus ntau qhov kev nyuaj siab thiab kev ntxhov siab. Qhov no ua rau nws yog cov khoom siv muaj txiaj ntsig hauv cov ntawv thov uas qhov hnyav txo qis thiab kev ua haujlwm ruaj khov yog qhov tseem ceeb, xws li hauv kev tsim dav hlau thiab tsheb. Tsis tas li ntawd, aluminium qhov kev tiv thaiv ntuj rau corrosion ua rau nws yog qhov kev xaiv zoo rau kev siv sab nraum zoov thiab marine.
Thaum raug rau cov huab cua, txhuas tsim ib txheej oxide tiv thaiv uas pab tiv thaiv nws ntawm xeb thiab kev puas tsuaj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov qauv thiab cov khoom siv uas raug dej noo thiab huab cua hnyav. Ib qho zoo ntawm cov raj txhuas yog lawv qhov ua tau zoo thiab malleability. Aluminium tuaj yeem yooj yim puab thiab tsim rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa, tso cai rau kev tsim qauv tshwj xeeb thiab cov lus qhia meej hauv ntau yam lag luam. Qhov kev ywj pheej no ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim vaj tsev thiab sab hauv tsev, nrog rau kev siv rau hauv kev tsim cov khoom thiab cov khoom. Ntxiv mus, txhuas yog cov khoom siv ruaj khov nrog kev siv rov qab tau zoo. Nws tuaj yeem rov ua dua tshiab ntau zaus yam tsis poob nws cov khoom, ua rau nws yog qhov kev xaiv zoo rau ib puag ncig rau cov lag luam thiab cov lag luam uas tab tom nrhiav kev txo lawv cov kev cuam tshuam rau ib puag ncig. Los ntawm kev siv cov txhuas rov ua dua tshiab, cov tuam txhab tuaj yeem pab txhawb rau kev lag luam ncig thiab txo cov khib nyiab.
Xaus lus, cov raj txhuas yog cov khoom siv muaj nqis thiab tseem ceeb hauv ntau yam lag luam, ua tsaug rau lawv lub zog, kev tiv thaiv corrosion, formability, thiab kev ruaj khov. Raws li thev naus laus zis thiab kev tsim kho txuas ntxiv mus, cov raj txhuas yuav tseem yog ib qho tseem ceeb hauv ntau daim ntawv thov, muab cov kev daws teeb meem ruaj khov thiab sib dua rau cov teeb meem ntawm lub ntiaj teb niaj hnub no.
