Boatbuilding with & Aluminum - Glen-L Boat Plans

But for the welded aluminum boat, the choices narrow down to the so-called marine alloys in the 5000 and 6000 series, the latter typically being extrusions. Yet even within these series there are still many alternatives. But the most common, readily available, and suitable for welded boat hulls include: 5052-H32 5052-H34 5083-H321 5086-H32 5086

The Effects of Saltwater on Metals - Sciencing

Apr 27, 2018· Saltwater and Metal. The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does. This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to

How to Straighten Bent Aluminum - Hunker

Bend the aluminum object as straight as you can with your hands. Depending on the thickness of the aluminum, you might not be able to bend it at all. Advertisement Step 2 Lay the aluminum object on a flat, solid surface, like a concrete floor. Use a heat gun to warm the part of the aluminum you wish to straighten.


Fiberglass boats will have the aesthetic advantage of having better visual looks and hull shapes. Since the material is molded, more advanced and attractive shapes can be made. Aluminum construction on the other hand is made from cutting, bending and welding large sheets of aluminum and various other aluminum angles and extrusions, thus an
