Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

There are a few landmark building structures that use aluminum as a primary structural material. Key examples are the John Hancock Center Tower in Chicago (Fig. 7.1a) whose exterior bracing system is made of black anodized aluminum alloy, and the ALCOA building in San Francisco (Fig. 7.1b). Table 7.1.

To provide an introduction to metallurgical concepts necessary to understand how structural features of aluminium alloys are influenced by alloy composition, processing and heat treatment, and the basic affects of these parameters on the mechanical properties, and hence engineering applications, of the alloys.

2020年11月13日 · Aluminum is a chemical element with atomic number 13 which means there are 13 protons and 13 electrons in the atomic structure. The chemical symbol for Aluminum is Al. Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group.

2020年3月4日 · Aluminum atoms are arranged in a face-centered cubic (FCC) structure with a melting point of 660°C. There are nine different series of aluminum, which will be discussed later in this section, four of which are referred to as heat-treatable aluminum alloys, and these alloys are so-called because of the potential to increase the mechanical ...
