Aluminum sheet for boat building has many desirable properties that have made it popular for boats and related marine parts. First of all, aluminum is lightweight, one of the most important considerations when designing a boat. But its lightness does not mean it isn’t strong. Aluminum alloys have been developed that can match or even surpass steel when it comes to strength to weight ratio.

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 marine grade aluminum so revolutionary in so many industries. In fact, for certain kinds of vessels, aluminum is too lightweight, and its use in the hull would make them too buoyant and susceptible to sharp dips and turns on choppy water. Of course, this is only an issue in a small number of cases.

To be sure, it is when dealing with marine environments, where salt water will be an issue, that aluminum truly begins to shine. Aluminum sheet for boat building are developed with corrosion resistance in mind. First off, aluminum's natural oxidization process gives it tremendous protection from all kinds of elements. Plus, when potential corrosion is a primary concern, such as for boats and ships, protective coatings can be added, bolstering an alloy’s already high tolerance for salt water.
