5XXX series aluminum plate is popular on boats
While boats may not be among the most well-known applications for aluminum,
the marine industry has undergone a technological revolution thanks to the
unique properties of aluminum plate on boats.
In some cases, the entire hull of a boat is made from aluminum, while in many vessels, particular parts and equipment are made from aluminum, such as ladders, railings, and gangplanks.
First off, the 5XXX series aluminum alloys are extremely popular on boats.
These alloys offer weld yield strengths from 100 to 200 MPa and feature good
weld ductility without the need for heat treatment. They are also renowned for
their high corrosion resistance. Seawater tests have shown that after ten years
of use, the tensile strength of 5XXX series alloys show reductions of only 2 to
5 percent.
Three alloys that are considered marine grade are 5052 aluminum plate, 5083 aluminum plate, and 5086 aluminum plate. All three are produced primarily as rolled materials (in sheet or plates) and are commonly found in boat hulls. With high tensile strength at weld points and excellent corrosion resistance, these alloys are ideal for use in marine applications.
The 6XXX series offers two more alloys of marine grade that are particularly well suited to seawater, 6061 and 6063 aluminum sheet plate cut to size. The former, with a yield strength of 40,000 psi, is among the most commonly used aluminum alloys across all industries, and is again a top choice for boat hulls. The latter, while not as strong as 6061, does offer greater formability, and features a high surface finish that is good for anodizing.
This is aluminum has many desirable properties that have made it popular for boats and related marine aluminum sheet parts. First of all, flat aluminum plate is lightweight, one of the most important considerations when designing a boat. But its lightness does not mean it isn’t strong.
Another point in favor of aluminum is its high yield strength, resulting in aluminum parts, in particular hulls, that can take quite a pounding before they begin to deform. Its combination of tremendous strength and extremely light weight is what has made aluminum so revolutionary in so many industries.
