Aluminium yog siv nyob rau hauv hulls, deckhouses, thiab hatch npog ntawm coj mus muag ships, raws li zoo raws li nyob rau hauv cov khoom siv, xws li ntaiv, railings, gratings, qhov rais, thiab qhov rooj. Qhov kev txhawb siab loj rau kev ua haujlwm aluminium yog nws qhov hnyav txuag piv rau cov hlau.
Lub ntsiab zoo ntawm qhov hnyav txuag nyob rau hauv ntau hom marine nkoj yog nce payload, nthuav lub peev xwm rau cov cuab yeej, thiab txo hwj chim xav tau. Nrog rau lwm yam ntawm cov hlab ntsha, cov txiaj ntsig tseem ceeb yog tso cai kom zoo dua qhov kev faib tawm ntawm qhov hnyav, txhim kho kev ruaj ntseg thiab ua kom muaj txiaj ntsig zoo tsim lub nkoj.
Lub 5xxx series alloys siv rau feem ntau ntawm kev lag luam marine daim ntawv thov muaj weld yield zog ntawm 100 mus rau 200 MPa. Cov txhuas-magnesium alloys khaws cov vuam zoo zoo yam tsis muaj kev kho cua sov tom qab vuam, thiab lawv tuaj yeem tsim nrog cov txheej txheem nkoj thiab khoom siv. Lub weldable aluminium-magnesium-zinc alloys kuj tau txais kev saib xyuas hauv daim teb no. Kev tiv thaiv corrosion ntawm 5xxx series alloys yog lwm qhov tseem ceeb hauv kev xaiv ntawm txhuas rau kev siv dej hiav txwv. 6xxx series alloys, dav siv rau kev lom zem nkoj, qhia txog 5 txog 7% txo qis hauv cov kev sim zoo sib xws.
