2024 aluminium alloy yog ib hom kev siv zog siab zog, uas tuaj yeem ua kom muaj zog los ntawm kev kho cua sov. Nws muaj nruab nrab plasticity nyob rau hauv quenched thiab cia li-quenched xeev, zoo chaw vuam, thiab muaj ib tug nyiam tsim intergranular tawg thaum siv roj welding. Tom qab quenching thiab txias ua hauj lwm hardening, lub alloy yog nws machinability yog tseem zoo, tab sis lub machinability tom qab annealing yog tsawg: lub corrosion kuj tsis siab, thiab anodizing kev kho mob thiab painting txoj kev yog feem ntau siv los yog saum npoo yog coated nrog txhuas txheej los txhim kho. nws corrosion kuj. Kev Siv Nws yog tsuas yog siv los ua ntau yam khoom siv siab thiab cov khoom siv (tab sis tsis suav nrog cov khoom siv hlau nplaum) xws li cov pob txha pob txha, tawv nqaij, pob txha taub hau, tis tav, tis tis, rivets, thiab lwm yam haujlwm hauv qab 150 degree ntawm lub dav hlau.
