. Physical Properties of Aluminum: Aluminum is a silvery-white metal with no odor or taste. With the addition of silicon, the material becomes more malleable and soft. The cubic structure of the aluminum crystal is face-centered aluminiu. Aluminum has a lower density than any other commercial metal except for magnesium.. Aluminium alloy - Wikipedia aluminiu. An aluminium alloy ( UK / IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are . aluminiu. Facts About Aluminum | Live Science. Just the Facts aluminiu.

Aluminium - Wikiwand

Aluminium 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 aluminiu. Aluminium visually resembles silver, both in its color and in its great ability to reflect light.. Aluminium - Simple English Wikipedia, the free encyclopedia. It is a highly reactive metal, although it is corrosion resistant aluminiu. A fresh film of aluminium is a good reflector of visible light and an excellent reflector of medium and far infrared radiation . aluminium prevents corrosion by forming a small, thin layer of aluminium oxide on its surface.. History of aluminium - Wikipedia. Crystals of alum, the naturally occurring form of which was known back to the ancients. The history of aluminium was shaped by the usage of its compound alum.The first written record of alum was in the 5th century BCE by Greek historian Herodotus. The ancients used it as a dyeing mordant, in medicine, in chemical milling, and as a fire-resistant coating for wood to protect fortresses from .. WebElements Periodic Table » Aluminium » the essentials. Pure aluminium is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is somewhat decorative. It is easily formed, machined, and cast. Pure aluminium is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements . aluminiu. Aluminium: Specifications, Properties, Classifications and Classes. Alloy Designations. Aluminium is most commonly alloyed with copper, zinc, magnesium, silicon, manganese and lithium. Small additions of chromium, titanium, zirconium, lead, bismuth and nickel are also made and iron is invariably present in small quantities. There are over 300 wrought alloys with 50 in common use. aluminiu. What is aluminium. Light, durable and functional: these are the qualities that make aluminium one of the key engineering materials of our time aluminiu. We can find aluminium in the homes we live in, in the automobiles we drive, in the trains and aeroplanes that take us across long distances, in themobile phones and computers we use on a daily basis, in the shelves inside our fridges and in modern interior designs, but a .. Aluminum Alloy: Definition, Characteristics, Types, Properties, and .. Here are the characteristics of aluminum alloys: Lightweight: Aluminum alloys have low densities, making them lightweight and ideal for applications where weight is a critical factor. Corrosion Resistance: The surfaces of aluminum alloys form a natural oxide layer that protects against corrosion in many environments. aluminiu. Aluminum Definition & Meaning - Merriam-Webster aluminiu. aluminum: [noun] a bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation and is the most abundant metal in the earths crust where it always occurs in combination — see Chemical Elements Table.. What is Aluminum? (with pictures) - AllTheScience. The history of this element is actually quite old aluminiu. Various forms have been used for centuries; aluminum oxides, for example, appear in pottery and glazes from Ancient Egypt. The Romans also used it, in the form of a substance they called alum.In the 1800s, Hans Christian Oersted isolated an impure form of the element, and he was followed by Friedrich Wohler, who succeeded in isolating the pure ..
