Aluminum is the most abundant metal and the third most abundant element in the earth’s crust, after oxygen and silicon. It comprises about 8% of our planet’s mass.

Aluminum is a silvery-white metal with many valuable properties. It is light (density 2.70 g/cm3), non-toxic, and can be easily machined or cast. With an electrical conductivity 60% that of copper and a much lower density, it is used extensively for electrical transmission lines. Pure aluminum is soft and brittle, but can be strengthened by alloying with small amounts of copper, magnesium, and silicon.

Aluminum is too reactive chemically to occur naturally as the free metal. Instead, it is found combined in over 270 different minerals. The chief ore of aluminum is bauxite, a mixture of hydrated aluminum oxide (Al2O3xH2O) and hydrated iron oxide (Fe2O3xH2O). Another mineral important in the production of aluminum metal is cryolite (Na3AlF6).

Corrosion Properties:

Based solely on its chemical reactivity, aluminum should not be very useful at all. Its standard reduction potential is -1.66 volts, indicating that it is a very good reducing agent. It is far more active than iron, which has a reduction potential of -0.44 volt. Aluminum weathers far better than iron, however, because the product of its corrosion, Al2O3, adheres strongly to the metal’s surface, protecting it from further reaction. This is quite different from the behavior of iron’s corrosion product, rust. Rust flakes off the surface of iron, exposing the surface to further corrosion.

Recycling of aluminum saves considerable energy. Because the aluminum is already in the metallic state, all of the energy spent in purifying the ore and reducing it to the metal is saved when aluminum is recycled. The aluminum needs only to be melted to be reused. Aluminum has a rather low melting point, 660C, and requires only 26 kJ/mol to melt. To reduce a mole of Al from Al2O3 requires over 780 kJ.

Aluminum Applications:

Automotive, Can, and Structural Applications

Automotive, Can, and Structural Applications Aluminum is used in four major areas; the automotive industry, cans and other packaging materials, the electrical industry, and for structural applications.

Aluminum is light, offering a high strength-to-weight ratio so important to industries like transportation, where Alcan is an industry leader in developing new applications.

Equally important are aluminum’s thermal conductivity, versatility and decorative potential, especially for packaging and building products.

Its high electrical conductivity has long made aluminum a material of choice in the electrical industry.

For structural applications, aluminum reduces the load demand on foundations in both industrial and residential buildings; it can be anodized or painted, meeting designers’ aesthetic needs; and, when extruded, aluminum offers an almost unlimited range of profiles and shapes.

Steel is iron that has been combined with other elements such as carbon, manganese and silicon. It falls into one of two families: carbon steel or alloy steel. Carbon steels are basic steels which harden only with surface (case) treatments. Alloy steels contain added elements that cause the steel to exhibit enhanced properties when heat treated.

Stainless Steel

Stainless steels are alloys of iron to which at least 10% chromium has been added to impart corrosion resistance. A 10% chromium steel will not rust when exposed to weather. To obtain greater corrosion resistance, more nickel and chromium are added to the alloy. Along with iron and chromium, all stainless steels contain some carbon. The carbon is added for the same purpose as in ordinary steels- to make steel stronger. Other alloying elements are added for improved corrosion resistance, fabric’ability and variations in strength. These elements include nickel, molybdenum, copper, titanium, silicone, aluminum, sulfur and many others.
