Fine Qualities of Aluminium Alloy for Boats

Blog | 08 May 2017

Aluminium is a lightweight metal, a multipurpose material whose application base is now outpacing steel, at least in transport-centric applications. The light alloy dominates aerospace materials, it’s used in cars and trucks, and you’re seeing aluminium alloys in boat construction. It’s obviously a capable material, one that’s taking over every industry and commercial enterprise. Boat construction, though, what are the advantages of an aluminium alloy here?

The Malleable Alloy 

Engineers talk about aerospace aluminium all the time. It’s the robust but light structural medium of choice in this high-flying industry. It won’t corrode easily, but the surface can be anodised. Basically, this common metal has a role to play in every contemporary setting, even the kitchen. Its status as a common metallic element is then matched by a workability feature, for this transformable alloy is relatively easy to process. In boat construction, aluminium alloys bend and shear readily. Panels are shaped and rolled with dispatch, and a light but strong boat frame quickly takes shape.

A Readily Repairable Boat Material 

The workshop environment uses this alloy every day, perhaps to fabricate kitchen trolleys or window frames. It’s everywhere, this corrosion-resistant metal. That state of affairs guarantees a firm fabrication infrastructure, which is just what you need when your aluminium boat frame is damaged. Accidents happen, after all, but your metal-reinforced boat will easily reject most bumps. If the impact does cause significant damage, then the metal base creates a crumple zone, a means of mechanically absorbing the impact. Now, a plastic glass hull will crack under the force of a collision, but a slightly dented aluminium alloy is easy to fix, especially when the repair yard has access to the workshop fabrication infrastructure mentioned above.

Exibits Ductility-Assured Formability 

In the past, boating enthusiasts imagined metal frames as clunky, square-edged affairs. The envisaged boat would likely handle poorly and look like a graceless tub. In point of fact, nothing could be further from the truth, not when you know about the ductility characteristics of this light but strong metal. A contoured hull with a water-cutting form factor is the result of a formability factor that goes above and beyond what can be achieved by other engineering solutions, including fibreglass resins. On top of that svelte outline, the aluminium alloy is easy to embellish, but its exposed metal surface won’t degrade, not because of water or ultraviolet-heavy sunshine.

Malleable aluminium alloys are used in boat construction as an ideal marine engineering solution. They’re light, strong, corrosion-resistant, and UV resistant. Back in the workshop, the metal is workable and ductile, so it readily takes on complex profiles, the kind of shapes that enable a stretched hull to power through any water and any weather condition.
