Nco tseg:
5052-H32 feem ntau yog siv rau cov nplooj ntawv uas xav tau lub zog nruab nrab nrog cov qauv zoo heev.
5083-H116 lossis H321 yog nyiam rauwelded marine qauvrau txhim kho corrosion kuj thiab ruaj khov ncej-weld zog.
Kev ua haujlwm hauv Marine Environments
Ob lub alloys tiv tauspitting thiab localized corrosionnyob rau hauv dej hiav txwv vim muaj magnesium cov ntsiab lus thiab ruaj khov oxide zaj duab xis.
5083yog nyiam rau kev txhoj puab heev lossis ntev - daim ntawv thov marine qhov twglub zog muaj zogyog qhov tseem ceeb.
Galvanic compatibility:Siv dielectric teeb meem, insulating pads, los yog tau tshaj fasteners (stainless steel nrog kev sib cais) los tiv thaiv galvanic corrosion.
Fatigue resistance:Zoo rau lub plhaub plating; 5083 muaj kev ua tau zoo dua vim yog lub hauv paus muaj zog dua.

Tsim & Xaiv Kev Qhia
Siv5052rautsis yog- cov vaj huam sib luag, cov khoom siv sab hauv, tso tsheb hlau luam, thiab cov khoom siv ntxivqhov twg formability tseem ceeb heev thiab load yog nruab nrab.
Siv5083rauhull plating, structural tswv cuab, thiab siab - siv zogqhov twg tiv thaiv kev ntxhov siab -corrosion cracking yog qhov tseem ceeb.
Qhia kom tsim nyog temper (H116, H321) rauwelded qauv.
Thickness xaiv yuav tsum tau raws li qhov yuav tsum tau khoov nruj thiab buckling; aluminium xav tau me ntsis thickness ntau dua steel rau qhov sib npaug sib npaug tab sis muaj qhov hnyav hnyav.
Tiv thaiv cov pob qij txha thiab kev sib cuag nrog cov hlau sib txawv uas siv cov rwb thaiv tsev thiab cov txheej txheem los tiv thaivgalvanic corrosion kuj.
Kev tuav & Kho
Yaug nrog dej tshiab hauv qhov chaw dej ntsev kom tshem tawm cov khoom pov tseg
Tshawb xyuas welds, fasteners, thiab seals ib ntus rau kev xeb lossis qaug zog
Rov ua cov txheej txheej raws li kev pom zoo; kho cov khawb kom sai
Tsis txhob sib cuag nrog cov hlau tsis sib xws ntev; siv cov ntxhua khaub ncaws tiv thaiv, lub tes tsho, lossis cov coatings
