Aluminum alloys and engineered materials

Aluminum alloys readily with copper, manganese, magnesium, silicon, and zinc Many aluminum alloys arc commercially available. See also Aluminum Alloys and Engineered Materials. 

Some of the foregoing topics are described in more detail in the following article on Aluminum Alloys and Engineered Materials. 

ALUMINUM ALLOYS AND ENGINEERED MATERIALS. Aluminum alloys have been used effectively for scores of years. Much... 

As pointed out by Stephens and Goldman (State University of New York at Stony Brook). Quasicrystals are neither uniformly ordered like crystals nor amorphous like glasses. Many features of quasicrystals cun be explained, but their atomic structure remains to be described fully. See also Aluminum Alloys and Engineered Materials... 

Aluminum oxide (alumina), AI2O3, has lugh technological value. Sol-gel processing of alumina has created novel applications and improved some of its properties. Products such as catalyst earners, abrasives, fibers, films for electronic applications, aerogels, and membranes for molecular filtration have been developed based on sol-gel processing. See also Alumina Adsorption (Process) and Bauxite Aluminum and Aluminum Alloys and Engineered Materials. 

Though there are many possibilities of the engineering alloys, let us consider three common alloys from different classes a steel, an aluminum alloy, and a titaninm alloy. The three alloys and their appropriate design properties are listed in Table 8.3. The values that are the most favorable in each category are listed in bold typeface. On the basis of Criterion 1, the best material is maraging steel, but from the viewpoints of Criteria 2 and 3 the titanium alloy is obviously superior. Cost is an additional factor that could influence the final selection. 

Aluminum may be alloyed with a number of elements to produce a series of useful engineering materials. For properties of some aluminum alloys and their uses see Table 4.12.
