I wouldn't go as far as saying significant differences in corrosion mr Vietnam , 5000 series and 6000 series have different compounds , if you can imagine a 4m boat has a tighter shape in the hull you will use a 5025 series to pull in that sheet to the frames . Another example is a 9.5m naiad hull we used a 8mm still in the 5000 series to compensate for the tight V in the nose . The bigger vessels even 18m use the 5000 series also . It's all good stuff m8 I wouldn't loose sleep over grades. The idea behind aluminium is use New Zealand made stuff it's the best of the best , Chinese and Indonesian aluminium have a high copper nickel and lead content to replace the important stuff called silicone. So might pay to ask the manufacturer where they got there material
