Take care walking on the surface of a spill to avoid stepping into a pocket of molten aluminum below the crust. News 32:258 (1954)]; [UL Bull. Give a detonable mixture with liquid oxygen [NFPA 491M 1991]. When combined with other metals like copper, aluminum is strong. Privacy Policy, Copyright © 2013- document.write(new Date().getFullYear()), Materials Science and Engineering: An Introduction, Aluminum Structures: A Guide to Their Specifications and Design, Room Temperature Density Values for Aluminum Alloys. The low density explains the use of aluminum in the aerospace industry and other transport industries. Aluminum and aluminum alloys are characterized by a relatively low density compared to steel. Save my name, email, and website in this browser for the next time I comment. 39 (1968)]. Density helps to predict the behavior of a substance when it interacts with others. World Leader in the Metallurgical Materials. What Is The Biggest State In The United States? Kedzierski a,*, R. Brignoli , K.T. The metal has a boiling point of 2,470°C and a melting point of 660.3°C. Protective equipment designed for chemical exposure only is not effective against direct contact.

Mixtures with finely divided bromates (also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium or zinc can explode by heat, percussion, and friction, [Mellor 2:310 (1946-47]. The density of the alloys of aluminium does not vary widely from this figure ranging between 2,640kg/m3 and 2,810kg/m3. Eng. The test results showed that molten density decreases with increase in temperature and Al 2 O 3 addition ratio, and increases with the addition of Sm 2 O 3, and/or Al 2 O 3 + Sm 2 O 3. and density values of aluminum alloys don't vary much. The estimate of gas content is quantified in a numerical value called Density Index.

Aluminum also forms a compound known as aluminum oxide, which used in industrial processes. Three industrial explosions involving a photoflash composition containing potassium perchlorate with aluminum and magnesium powder have occurred [ACS 146:210 1945], [NFPA 491M 1991]. Web site owner: The more space an object occupies, the lesser dense it will be. 3 for the bottom pouring, the casting density tends to decrease, as the melt velocity increases. Address About liquid aluminum; 1 cubic meter of liquid aluminum weighs 2 375 kilograms [kg] 1 cubic foot of liquid aluminum weighs 148.26641 pounds [lbs] Liquid aluminum weighs 2.375 gram per cubic centimeter or 2 375 kilogram per cubic meter, i.e. The density of aluminum is constant, but heavier than that of water. In fact, it only has a third of the density of iron. Density - Density of different solid materials, liquids and gases. Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. The density of aluminum is about 2700 kg/km3, which is equivalent to 2.7g/cm3. All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com, Countries With the Lowest Population Density, South American Countries by Population Density, 5 Things You Should Know About: Central America. Therefore, the specific gravity difference between this oxide film and the aluminum water is small. 1: 1956]. Room 1306, Tower A, International Business Center, No.72, Nongye Road, Jinshui District, Zhengzhou City, Henan Province, China.

In the Density Index Unit (DIU), Energy Systech provides a very powerful tool to an aluminium casting shop. Fermi National Accelerator Laboratory; U.S. Department of Energy Office of Science; Kirk Road and Pine Street; Batavia IL 60510-5011. The density of aluminum is about 2700 kg/km3, which is equivalent to 2.7g/cm3. This section provides a listing of alternate names for this chemical, Normally stable but can become unstable at elevated temperatures and pressures. Reacts exothermically if mixed with metal oxides and heated (thermite process). The atomic number of aluminum is 13, and it has an atomic mass unit of 26.98.
