Txheej txheem cej luam ntawm 7075-T651 Aluminium Phaj
7075 yog zinc-alloyed aluminium paub txog nws lub zog tshwj xeeb, piv rau ntau cov hlau thaum hnyav li ib feem peb li ntau. Nws yog qhov muaj zog tshaj plaws feem ntau muaj aluminium alloy, ua rau nws cov khoom xaiv qhov twg qhov kawg ntawm lub zog-rau-qhov hnyav piv yuav tsum tau.
Cov t651 ua muab kev ntxhov siab-relieved phaj nrog tsawg warping thaum lub sij hawm machining. Cov txheej txheem kev ntxhov siab tom qab kev daws teeb meem kev kho cua sov thiab kev laus ua kom muaj kev ruaj ntseg ntawm qhov ntev - qhov tseem ceeb tshaj plaws thaum machining loj cov yam ntxwv los yog precision pwm kab noj hniav.
7075 ua tsis pom zoo rau welding vim nws cov ntsiab lus zinc thiab susceptibility rau kev nyuaj siab corrosion cracking nyob rau hauv weld cheeb tsam. Kev sib koom ua ke feem ntau ua tiav los ntawm kev siv tshuab fastening, nplaum nplaum, lossis kev sib txhuam do vuam rau cov ntawv tshwj xeeb.
Dav siv nyob rau hauv aerospace, kev tiv thaiv, thiab kev siv zog siab, 7075-T651 phaj yog tsim rau AMS 4045 thiab ASTM B209 tus qauv. Tag nrho cov khoom siv nkoj nrog daim ntawv pov thawj zeb tag nrho (EN 10204 3.1) thiab cov ntaub ntawv soj ntsuam ultrasonic rau thickness saum 25 hli.
