4. Kev Sib Piv: 5083 vs 5086 vs 6061

5. Fabrication cov lus qhia rau marine txhuas daim hlau

Vuam:Siv 5356 lossis 5183 tus tub lim hlau rau 5xxx alloys; Zam txhob overheating kom tsis txhob sib cais magnesium cais.

Corrosion tiv thaiv:Anodize lossis siv cov tub rog -}} txheej txheem tsho rau 6061; tiv thaiv galvanic corrosion thaum nyob rau hauv kev sib cuag nrog stainless hlau lossis tooj liab.

Kev xaiv tsim tsim:Siv 5xxX alloys rau cov khoom siv raus hluav taws xob; 6061 haum rau tsis yog -}}} itached, cov txheej txheem ntu.

6. Kev ua tsis tau thiab rov ua dua tshiab

Aluminium yog100% rov ua dua tshiab, txo qhov kev cuam tshuam ib puag ncig.

Cov tubrog nkoj - qib alloys tswj lawv cov yam ntxwv tom qab rov ua dua tshiab, txhawb nqa aKev lag luam ncig.
