Titanium is a great alternative for structural material in terms of weight and strength. Titanium is lighter than Steel and much stronger than Aluminum. It has a low …heat transfer rate, which makes it useful for high-heat applications..
The one major draw-back with titanium is that it retains heat during maching of part during manufacture due to its low heat transfer rate. Titanium has to be machined at 1/5 the rate of steel, even with plenty of coolant applied to the cutting tool. This is one reason a Titanium part is more expensive; if it takes 5 times longer to machine a part, it will be 5 times more costly. The other reason is that Russia has a monopoly on the titanuium resources..
Someone asked me which part would be lighter if made for the same load: Steel, Titanium or ALuminum. I analyzed a simple rod under an axial load and determined the minium size of the optimized rod then calculated its weight. The Titanium rod came out 1/3 lighter than the Steel rod. For bending or other load applications, this ratio will vary. The strength ratio can easily be found by ratioing the Young's Moduls and the unit weight..
Fatigue -- A few years ago, Titanium did not have very good fatigue properties. The standard titanium alloy was Titanium 6Al-4V . The fatigue S/N curve of this alloy is very steep; it does not flatten out at the higher cycles as Steel S/N curves will do. However, new alloys have been developed that have much better fatigue properties. (MORE)

In a short word, we get titanium by chemistry method from titanium ores. .
Here is a brief introduction of the process as follow. .
For the smelting of titanium minerals are… mainly ilmenite (FeTiO3), rutile (TiO2) and other perovskite. The treated ore to be volatile titanium tetrachloride, and then restore the obtained titanium magnesium. .
Commonly used industrial method of sulfuric acid decomposition of ilmenite Preparation of titanium dioxide, titanium dioxide Preparation by the titanium tetrachloride. Concentrated sulfuric acid treatment grated Ilmenite (concentrate), took place the following chemical reaction: FeTiO3 +3 H2SO4 Ti (SO4) 2 + FeSO4 +3 H2O FeTiO3 +2 H2SO4 TiOSO4 + FeSO4 +2 H2O FeO + H2SO4 FeSO4 + H2O Fe2O3 +3 H2SO4 Fe2 (SO4) 3 +3 H2O In order to remove impurities Fe2 (SO4) 3, by adding iron filings, Fe3 + reduced to Fe2 +, and then the solution cooled to below 273K, making FeSO4 â¢ 7H2O (green vitriol) as a by-product of crystallization. Ti (SO4) 2 and TiOSO4 water metatitanic parse out the white precipitate, the reaction is: Ti (SO4) 2 + H2O TiOSO4 + H2SO4 TiOSO4 +2 H2O H2TiO3 + H2SO4 Calcination metatitanic that obtained Ti: H2TiO3 TiO2 + H2O The industrial system, titanium tetrachloride reduction method to restore the use of titanium dioxide. The TiO2 (rutile or natural), and charcoal powder mixture is heated to 1000 ~ 1100K, chlorination treatment, and to generate TiCl4, vapor condensation. TiO2 +2 C +2 Cl2 = TiCl4 +2 CO .
Reductant C 2Mg + TiCl4 2MgCl2 + Ti "excessive amount of magnesium," Mg + 2HCl == MgCl2 + H2.

It's extremely doubtful that anyone has. Titanium is a natural element (symbol Ti, and atomic number 22) listed in the periodic table! Patent law typically applies to man-made… (i.e., non-natural) materials, items (products and designs), processes, and similar use of materials and ideas. For example, there are records of patents for certain smelting processes used in steel manufacture, but there would not be patents for the individual natural ores and metals used in steel-making. The patent laws are primarily intended to protect ownership rights, manufacture, and rights to sale of derived products. (MORE)
Most of the world's titanium is mined as titanium dioxide (inrutile) in mines located in southwest Africa, Russia, Kazakhstan,Australia, and the US states of Virginia and Kent…ucky. In India, titanium metal extraction is developed indigenously byDRDO and commercial production is started at Kerala Minerals andMetals Limited. (MORE)
