Aluminum Sheet for boat building is always called marine grade aluminum sheet. It is more and more popular for ship building, vehicle, tank trailer, Oil tank usage. This require the aluminum sheet have to be suitable for use in some marine environment, it has a very good quality of corrosion resistance, and very good performance of welding.

Aluminum Sheets for Boats Alloy 5052 H32
Alloy 5052 and 5083 are marine grade aluminum sheet and also called aluminum-magnesium. Those two alloy number are non-heat-treatable aluminum,it has good welding performance and the hardness is allow 90 degree bending without crack.
Aluminum Sheets for Boats Alloy 6061 T6
The alloy 6061 and 6082 are marine grade aluminum sheet and also called aluminum-magnesium-Si alloy. Those alloy number can be produced with temper T6 or T651, the plate hardness can be above 95HB after the heat treatment. Due to the hardness, the 6061 and 6082 always can’t make any bending and easy crack.The application always be ship yard or other part which no need do any bending.
What’s the best marine grade aluminum? What kind of aluminum is used for boats?
Aluminum sheets for boats always have very good quality of corrosion resistance, and very good performance of welding, so many customer use this alloy for ship building. The mainly allow number are 5052, 5754, 5083, 6061 and 6082. Each alloy number have different features, like 5052 H32 is always used for small boat building and also 5052 is the cheapest marine grade aluminum sheet. The alloy 5083 can be produced with H321 or H116 grade, because it contain over 4% magnesium elements. HC aluminum can provide DNV, CCS, BV or ABS certificate;
The hardest best marine grade aluminum alloy number is 6061 and 6082, the hardness is over 95HB
