Alloy 5052 and 5083 are marine grade aluminum sheets and also called aluminum-magnesium.
Those two alloy numbers are non-heat-treatable aluminum, it has good welding performance and the hardness allow 90 degrees bending without crack.
The alloy 6061 and 6082 are marine grade aluminum sheet and also called aluminum-magnesium-Si alloys.
Those alloy numbers can be produced with temper T6 or T651, the plate hardness can be above 95HB after the heat treatment. Due to the hardness, 6061 and 6082 always can’t make any bending and easy cracks. The main applications are shipping yards or other parts which don’t need to do any bending.
