There are many grades of commercially available aluminum. Marine-grade aluminum are alloys that can handle exposure to sun and water due to the elements that are alloyed with the aluminum. Magnesium and silicon are the primary additions to bring the alloys up to marine grade. Some marine grades are more tolerant of salt water, which brings extra chemical stress to the metal.
Marine grade aluminum is used for boats, but can also be found on docks, railings, ladders, stairs, and other furnishings or items that are usually used on or near the water. Marine grades of aluminum can also be used in tanks or storage facilities: they are not exclusively used in marine situations.
Although aluminum is commonly used for floating watercraft, it is rarely used for submarines. The compression forces involved in diving wreak havoc on aluminum, causing eventual fatigue and cracking. Additionally, the constant exposure to sea water without air speeds corrosion.
