5356...it's stronger and has proper amount of magnesium in it for 5083. None critical stuff you could get away with the 4043. |

I've used both. $043 is more flexable or ductile. It has been said that 4043 is not the choice for hulls in salt water. We I live about 90 min from gulf and most builders use 4043 and haven't had any issues. Now, in my personal experience, 5356 is a harder material and depending on what and how you are using it, it is more prone to crack. But again, that's my personal experience. |

I'd buy both and on ribs and hull seams I would only use the 5356. On decking stuff you could probably choose either. That 4043 welds easier with the thin stuff like decking. |
