7A04 Aluminium Alloy
7A04 yog ib qho ultra-siab zog aluminium alloy ntawm Al-Zn-Mg-Cu system, tseem hu ua super-hard aluminium, uas yog cov paub tab thiab siv dav hauv super-nyuaj txhuas. Nws yog ib qho siv tau ntev thiab dav siv alloy. Nws muaj lub zog siab, kev kho cua sov zoo ntxiv zog, thiab nruab nrab plasticity nyob rau hauv lub xeev annealed thiab tshiab quenched; Tsis zoo li rugged aluminium, corrosion kuj nyob rau hauv lub dag lub zog yog zoo dua li nyob rau hauv lub natural aging lub xeev, thiab lub ntuj aging txheej txheem qeeb, nws yuav siv sij hawm 3 lub hlis mus txog rau lub ncov ntawm cov laus hardening, yog li 7A04 yog siv nyob rau hauv lub quenched dag. lub xeev laus. Nws qhov tsis zoo yog cov koom haum tsis muaj kev ruaj ntseg, tsis tshua muaj zog qaug zog ntawm qhov tsawg zaus, thiab nyiam kev ntxhov siab corrosion rupture. Cov hlau muaj qhov zoo ntawm qhov vuam vuam, tsis zoo vuam vuam, thiab kev ua haujlwm zoo tom qab kev kho cua sov, tab sis tsis zoo tom qab annealing.

Daim ntawv thov ntawm 7A04 Aluminium Alloy
7A04 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 hauv phab ntsa thiab 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 qhov zoo ntawm kev ntxhov siab corrosion cracking. Nws kuj yog 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.
