Product Description
7075 txhuas bar yog ib tug txias-kho forged alloy nrog siab zog, deb superior rau me me hlau.7075 yog ib qho ntawm cov khoom siv muaj zog tshaj plaws uas muag muag.Zoo corrosion kuj, zoo mechanical zog thiab anodic cov tshuaj tiv thaiv.Cov nplej zoo dua muab kev sib sib zog nqus zoo dua, txhim kho cov cuab yeej hnav tsis kam thiab sib txawv xov dov.7075 txhuas yog hu ua ultra-high-strength aluminium alloy.Lub zog yield ntawm cov hlau yog ze rau lub zog tensile, qhov sib piv ntawm cov yield yog siab, thiab lub zog tshwj xeeb kuj yog siab, tab sis lub plasticity thiab siab kub zog yog tsawg.Lub alloy yog yooj yim rau txheej txheem, muaj zoo corrosion kuj thiab siab toughness.Qhov no alloy yog dav siv nyob rau hauv aviation thiab aerospace thiab tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv daim teb no.7075 aluminium bar khoom muaj cov yam ntxwv ntawm lub zog kub-kho tau alloying, zoo txhua yam khoom, ua haujlwm tau zoo, yooj yim ntawm kev ua, hnav tsis kam, corrosion kuj, oxidation kuj thiab lwm yam.
