<div dir="ltr" style="text-align: left;" trbidi="on"> <br /> <div class="MsoNormal"> <span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">The origin of aluminum alloys in aircraft construction started with the first practical all-metal aircraft in 1915 made by German company, of materials said to be `iron and steel'. Steel presented the advantages of a high modulus of elasticity, high proof stress and high tensile strength. Unfortunately these were accompanied by a high specific gravity, almost three times that of the aluminum alloys and about ten times that of plywood. Aircraft designers during the 1930s were therefore forced to use steel in its thinnest forms. To ensure stability against buckling of the thin plate, intricate shapes for spar sections were devised.<o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;"><br /></span></div> <div class="MsoNormal"> <span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">In 1909 Alfred Wilm, in Germany, accidentally discovered that an aluminum alloy containing 3.5 per cent copper, 0.5 per cent magnesium and silicon and iron, as unintended impurities, spontaneously hardened after quenching from about 480°C. The patent rights of this material were acquired by Durener Metallwerke who marketed the alloy under the name Duralumin. For half a century this alloy has been used in the wrought heat-treated, naturally aged condition. The improvements in these properties produced by artificial ageing at a raised temperature of, for example, 175°C, were not exploited in the aircraft industry until about 1934.<o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">In addition to the development of duralumin (first used as a main structural material by Junkers in 1917) three other causes contributed to the replacement of steel by aluminum alloys. These were a better understanding of the process of heat treatment, the introduction of extrusions in a wide range of sections and the use of pure aluminum cladding to provide greater resistance to corrosion. By 1938, three groups of aluminum alloys dominated the field of aircraft construction and, in fact, they retain their importance to the present day. The groups are separated by virtue of their chemical composition, to which they owe their capacity for strengthening under heat treatment.<o:p></o:p></span></div> </div>

The Aluminum & History Ketchup

<div dir="ltr" style="text-align: left;" trbidi="on"> <br /> In the beginning, there were horse trailers, alien during the backward 1950s if trail-riding became popular. Buyers didn’t feel suffering about the metal acclimated to body the trailer because the alone metal accessible was steel.<br /> Steel had some problems though. The bigger botheration was that it rusted. Even today, a lot of metal starts to blight afterwards alone a year of use. Over time, a metal can fall apart.<br /> When the all-aluminum horse trailer came on the bazaar in the 1970s, pioneered by Featherlike Trailers, it had a huge advantage over animate as a accomplishment material. Not alone did aluminum abide blight and corrosion, it was more lighter and accordingly easier to pull. Trailer owners advertisement bigger gas breadth if carriage an aluminum trailer alone added to its popularity.<br /> All-aluminum trailers tend to be added big-ticket than metal trailers, however. And metal trailer manufacturers affirmation aluminum trailers just can’t bear the accent of trail as able-bodied as a metal trailer. This leaves buyers with a harder choice-do they pay added for an all-aluminum trailer with its declared superiority, or buy a added accustomed animate bivouac and save money? Opinions alter wildly.<br /> </div>
