Aluminium

History: Alcoa was founded by Charles Martin Hall in 1888. Originally the company’s name was Pittsburgh Aluminum Company but in 1907 was renamed Aluminum Company of America. Alcoa is best known for its work with lightweight metals and today “Alcoa is a global leader in lightweight metals technology, engineering and manufacturing” (Alcoa Corporate Overview). In 1890 the company was trying to find a market for aluminum products. The first big product manufactured with Alcoa’s aluminum was…

Corrosion is when metals or other materials corrode over time. “Corrosion is a two-step process that requires three things: a metallic surface, an electrolyte, and oxygen. During the corrosion process, surface-level metal atoms dissolve into an aqueous solution, leaving the metal with an excess of negative charge.”(Corrosion, Boundless Chemistry, First two bullet points) The nail will undergo a corrosion process as it is placed in the cup filled with salt water. However, depending on the coating…

alloy within the 3xx.x series. The .1 (Axxx.1) indicates that it is a final shape of ingot. The composition, physical, mechanical properties of A356.1 Aluminium alloy are shown in table 2.3, 2.4, 2.5 respectively. Table 2.3: A356.1 Aluminium alloy Composition. ELEMENT Weight Percentage Aluminium (Al) 91.73 Silicon (Si) 7.23 Iron (Fe) 0.32 Copper (Cu)…

for 3 materials are: Copper- 220MPa , Aluminium- 40-50MPa , Iron- 3MPa. The following Yield strengths for 3 materials are: Copper- 70MPa , Aluminium- 15-20MPa , Iron- -. It can be said that copper is the strongest metal on it’s own, while aluminium is next and iron is the least. However, people can use iron as an alloy to create steel, which can be stronger up to 10x Most of the metals in Periodic Table have high malleability. This also includes iron, aluminium and…

where the frames are warped or loose, or where glazing is not securely fixed, the consequences can be serious. In Alderley Edge, school windows should be manufactured and installed by Sterling PVCU. They offer two different kinds of windows, aluminium and PVCU. There are numerous…

That is because, Scandium and Aluminium alloys are used in baseball bats which are so far successful. When added to aluminium, it strengthens the bat and the resilience without adding any excess weight. Since it has become very successful, scandium- aluminium alloy bats are very expensive because they rely on high performance. The most important benefit is the strength that is created when these two elements are combined. Before scandium was added, aluminium bats were used which were equally…

small stresses. Aluminium alloys have a tensile strength of 350MPa which is not as strong as high carbon steel or Carbon fibre reinforced polymers but is very high for a lightweight…

Alcoa Inc. Alcoa reported its fourth quarter and full year 2015 results last week on 11th January 2016. The company made an adjusted net profit of $ 65 million or $ 0.04 per share in the quarter while that of $ 121 million or $ 0.56 per share in the last year. The adjusted EBITDA for the fourth quarter was $ 590 million including $ 71 million of special items. The revenue for the quarter was $ 5.2 billion i.e. 18 % down from the same quarter of 2014 and 6 % down from the previous quarter. The…

shielding would stay the same. Aluminium has a lower ionisation energy than magnesium. This is because of the electronic configuration. The electronic configuration for aluminium is 1s2 2s2 2p6 3s2 3p1 and the electronic configuration for magnesium is 1s2 2s2 2p6 3s2. The outer electron for aluminium is in the p sub shell and the outer electron for magnesium is in the s sub shell. The energy in the p sub shell for aluminium is higher than that of the s sub shell for aluminium so less energy is…

robust and light body. Thus Ferrari produce some sports cars which are have full aluminium body. According the Aluminium Association, the F 360 Modena was built from 1999 to 2004 and had an all aluminium space-frame structure that was 40% stiffer than the steel F355. Also 100 kg lighter despite a 10% size increase (2013, p.37). Thanks to the aluminium body properties of car uplifted. Ferrari used the full aluminium body later to produce a Ferrari 612 Scaglietti from 2004 to…
