Today aluminum is obtained mainly by the Hall–Héroult method, which is exceptionally energy-intensive – nearly 5% of electricity generated in the US is utilized in the production of aluminum. Aluminum Is A Manufactured Metal With Unique PropertiesĪ metal ornament found in the tomb of a third-century Chinese military leader was found to be 85% pure aluminum, but how it was created is an unanswered mystery.Īluminum has an affinity to oxygen, and while scientists were aware of the existence of aluminum oxide as early as the late 18 th century, it was only in 1827 that a German, Friedrich Wohler, was able for the first time to extract the pure metal from the oxide. Aluminum certainly holds up in salt water, but it needs the proper treatment. The metal is also used in the manufacture of aircraft, in the construction industry, in packaging, and in many other fields where it is exposed to salt water in its various forms. Under certain conditions, though, aluminum will corrode and eventually break down unless these measures are taken.Īluminum is a popular choice with anglers as a material for their boats, so clearly, its ability to resist the corrosive action of saltwater is recognized. Resistance to corrosion is one of aluminum’s many positive attributes, and as long as specific protective measures are taken, it will hold up in salt water. However, unlike gold, silver, copper, and platinum, it’s rarely found uncombined in its pure form because it is inherently unstable and highly chemically reactive. Aluminum is the most abundant metal in the Earth’s crust, accounting for over 8% of all metals.
