aluminum (Al), chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most abundant metallic element in Earth’s crust and the most widely used nonferrous metal.
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.
Aluminum is soft, lightweight, fire-proof and heat-resistant, easy to work into new shapes, and able to conduct electricity. It reflects light and heat very effectively and it doesn't rust. It reacts easily with other chemical elements, especially oxygen, and readily forms an outer layer of aluminum oxide if you leave it in the air.
They are a class of elements distinguished by the following properties: ductility, malleability, hardness, conductivity, the ability to form alloys, and qualities of appearance.
This is because of its particular properties. It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking.
AA AAIA-2015 is a report that details specifications regarding aluminum and its alloys. It discusses how alloys are designated: aluminum wrought and cast alloys are specified in Tables 1 and 2 of AA AAIA-2015, and Table 3 details temper designation. The document also covers the advantageous characteristics of aluminum and its alloys that make ...
This comprehensive guide covers everything from its historical background, physical and chemical properties to its wide-ranging industrial and everyday applications. Learn about the element's safety aspects and its role in modern technology.
Characteristics. Aluminum is a lightweight, highly conductive, reflective and non-toxic metal that can be easily machined. The metal's durability and numerous advantageous properties make it an ideal material for many industrial applications.
Aluminium: Physical Properties, Characteristics and Alloys. 60 pages, 44 figures. Basic Level . prepared by Ron Cobden, Alcan, Banbury. Objectives: − to provide a survey of the aluminium alloys available to the user − to describe their various properties − to give an insight into the choice of aluminium for a proposed application.
Aluminium properties differ between grades depending on the alloy present giving each grades certain, unique characteristics. Within the family of metals only silver, copper and gold have better electrical conductivity.
