aluminum processing
Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 C (1,220 F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth's crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase Get price
