3003 rau AL-Mn system alloy, yog ib qho ntawm feem ntau siv xeb-pov thawj aluminium, qhov alloy no lub zog tsis siab (me ntsis siab dua cov khoom siv ntshiab aluminium), tsis tuaj yeem ua kom sov-kho kom muaj zog, yog li kev siv txias- kev ua haujlwm los txhim kho nws cov khoom siv kho tshuab: hauv lub xeev annealed muaj qib siab ntawm plasticity hauv semi-txias hardening ntawm plasticity tseem zoo, txias hardening ntawm plasticity tsawg, corrosion kuj zoo, weldability yog zoo, tsis zoo machinability. Kev siv yog tsuas yog siv rau cov kev cai ntawm high plasticity thiab zoo weldability, ua hauj lwm nyob rau hauv cov kua los yog gaseous xov xwm nyob rau hauv lub load uas tsis muaj load qhov chaw, xws li roj tso tsheb hlau luam, roj av los yog lubricating roj conduit, ntau yam kua ntim thiab lwm yam me me loads nrog rau zus tau tej cov khoom. sib sib zog nqus nqus qhov chaw: hlau siv los ua rivets.
