Titanium is preferred to other types of material because of its numerous qualitative properties<\/strong> such as lightness, robustness, low heat conductivity, low elastic modulus and high electrical resistance.<\/p>\n\n On equal resistance and ductility, titanium is lighter than steel<\/strong> and it's highly corrosion-resistant<\/strong> in the majority of oxidative environments. It is also atmospheric corrosion-resistant with any kind of urban and industrial pollution, moreover titanium has a good ductility and workability<\/strong>, in addition to an excellent resistance to traction.<\/p>\n\n Furthermore, titanium is not toxic, it doesn't contaminate, it's not magnetic, it has a good sound attenuation, it's UV and abrasion-resistant and it has also an excellent thermal inertia and a good workability and weldability level.<\/p>","AxFaq":"*RECURSION*"}}},"AxFaq_1":{"Id":7,"Category":"26e98d2b06ac11ded82892edeb5e647d","IsActive":true,"CreatedAt":"2013-03-20 12:32:39","UpdatedAt":"2013-03-20 12:32:39","SortableRank":2,"AxFaqI18ns":{"AxFaqI18n_0":{"Id":7,"Locale":"en_EN","Question":"What are some current examples of titanium applications?","Answer":" This material is widely used in different fields<\/strong>, shown below just few examples:<\/p>\n Grade 1<\/strong>: it's the commercially pure titanium with a low oxygen content and a low ultimate tensile strength. It's the most recommended on slim thickness for cold deformation and cold deep drawing. It is highly corrosion-resistant<\/strong> and it's also the best grade to be cladded on other types of material (less expensive).<\/p>\n\n Grade 2<\/strong>: it's the commercially pure titanium with a higher oxygen content than Grade 1. It's the most used grade because it guarantees a better compromise between corrosion resistance, weldability and formability<\/strong>. It's the perfect material for a wide range of chemical and marine applications, aviation industry components and also for heat exchangers, valves, forgings and pumps.<\/p>\n\n Grade 3<\/strong>: it's the commercially pure titanium with an even higher oxygen content than Grade 1 and 2. It has greater robustness, a less ductility and it's highly corrosion-resistant<\/strong>. It can be easily welded and it is used where the decrease of the thickness considering the best mechanical features is necessary.<\/p>\n\n Grade 5<\/strong>: it's a titanium alloy with very high mechanical features<\/strong> (2-3 times Grade 2). It's widely used in the applications for aerospace and automotive sectors, offshore, sports, medical field and where gas an oil are used.<\/p>\n\n Grade 7<\/strong>: it's the most corrosion-resistant<\/strong> and for this reason is widely used in the chemical industry, in the industrial components manufacturing and in the heat exchangers. Its mechanical features are the same of Grade 2.<\/p>\n\n Grade 12<\/strong>: it is highly corrosion-resistant and it's used in the chemical industry, in the industrial components manufacturing and in the heat exchangers. Its mechanical features are excellent<\/strong> (equivalent to steel AISI 316).<\/p>","AxFaq":"*RECURSION*"}}},"AxFaq_3":{"Id":9,"Category":"26e98d2b06ac11ded82892edeb5e647d","IsActive":true,"CreatedAt":"2013-03-20 12:38:31","UpdatedAt":"2013-03-20 12:38:31","SortableRank":4,"AxFaqI18ns":{"AxFaqI18n_0":{"Id":9,"Locale":"en_EN","Question":"Is titanium corrosion-resistant with acids?","Answer":" Titanium has an excellent resistance to oxidative environments<\/strong> such as nitric acid, chromic acid and bleaching solutions.<\/p>\n\n It is moderately resistant to reducing agents acids<\/strong> (hydrochloric and sulfuric acid) even if the corrosion of those acids could be inhibited by oxidative ions (such as Cu 2+, Fe 3+).<\/p>\n\n Titanium is not resistant to the corrosion caused by hydrofluoric acid, fluorides ( F-<3ppm) and alkaline solutions from hydrogen peroxide.<\/p>\n\n There is the possibility of ignition in dry chlorine (<0,5% H2O) and also in nitric acid. <\/p>\n\n Hydrogen absorption is possible with temperature higher than 200\u00b0C.<\/p>","AxFaq":"*RECURSION*"}}},"AxFaq_4":{"Id":11,"Category":"26e98d2b06ac11ded82892edeb5e647d","IsActive":true,"CreatedAt":"2013-03-20 12:40:16","UpdatedAt":"2013-03-20 12:40:16","SortableRank":5,"AxFaqI18ns":{"AxFaqI18n_0":{"Id":11,"Locale":"en_EN","Question":"Can titanium be colored?","Answer":" Yes, the coloring process is called \u201canodized oxidation<\/strong>\u201d. It's an electrochemical process whose aim is to thicken the oxide film<\/strong> which naturally covers titanium. The thickness of the film, which goes from few to few hundreds nanometres, determines the color<\/strong>.

Moreover, titanium has a quite attractive natural silver color that can change depending on how the material is treated.<\/p>\n\n We can find the first applications in this field in Japan back to the early '70s; in Europe the use of titanium in architecture can be attributed only to the 90's, a good example is the Guggenheim Museum in Bilbao<\/strong> (Spain).<\/p>\n\n This museum was inaugurated in 1997 and it is a spectacular building which required 60 tons of titanium<\/strong>. The choice of using the titanium can be considered farsighted, especially based on a economical evaluation which doesn't contemplate just the initial cost of the material itself, but also its duration which is almost eternal<\/strong>.<\/p>","AxFaq":"*RECURSION*"}}}}\n
