Titanium was discovered in 1790 but not purified to the early 1900’s . Moreover , titanium was not widely used until the second half of the 20 century . But now titanium has a 50 - year experience of modern industrial use and design to support its use . Most of its application has been in military applications like in aircrafts or gas turbine engines .
The latest includes golf clubs , and bicycles and jewelry . Due to its unique density , the corrosion resistance and its proper strength compared with competing materials such as aluminum , steels and super alloys , titanium have found its place in many industries . Some important facts or benefits of titanium alloys are the basis of widespread use of titanium today .
The root of name of this element is Titan . In Greece mythology Titans were known as a group of powerful gods . So this metal , which is very resistant and durable , has the name of Titanium .
Titanium and its alloys have high strength compared to their weight . These types of alloys are also very resistant to corrosion as they form a very thin but highly resistant layer of oxide . Titanium is used because of its low weight , strength , as well as its resistance to corrosion . It has some limitations , of course , because of the price of this metal , but new methods are being developed to reduce the costs of this metal and its alloys .
It is suitable for aerospace applications because of high weight strength and high corrosion resistance . However , the use of titanium is limited due to relatively high costs comparing with other materials such as aluminum alloys or steel alloys .
Therefore , it should be balanced between the benefits of using titanium and the extra costs .
The environmentis immune from titanium because the metal does not provide pollution . Where other architectural metals have a limited life , titanium resists .
Since titanium is one of the virgin metals , its connection with non – similar metals does not cause a galvanic corrosion . These properties , in addition with several unique properties , makes titanium the best choice for many applications from medical to aerospace .
Titanium is an element with low density ( approximately 60 % of the density of steel and super alloys ) , which can be strengthened by alloying and shaping . Titanium is non-magnetic and has excellent thermal properties . The thermal expansion coefficient is relatively less than steel and less than half of the aluminum coefficient .
The titanium and its alloys have a higher melting point than steel , but the maximum useful temperature for structural applications varies from 800°F to 1100°F , depending on its composition . Aluminad-titanium allolys are promising for applications at temperature ranging up to 1400°F .
The titanium element with Ti chemical symbol and atomic number 22 , is one of the intermediate metals in the periodic table of elements .
Titanium is mostly used as alloys with other metals . The air industry has the highest use of titanium alloys and use it in the body of planes , motor parts and spinners .
As a result of resistance of titanium against corrosion and chemical reactions , it is widely used in high – corrosion environments . An example of these environments is seawater, in which even stainless steel is exposed to corrosion .
Also in the manufacture of vessels , sea water desalination units and chemical reactors , this element and its alloys is used .
Every year , more than 1000 tons of titanium alloys are produced in order to use in pelvis surgeries and knee surgeries and prosthesis .
Another application of titanium alloys are in titanium implants . Currently , they use pure titanium sheets to decorate the high - rise buildings .
High strength of this metal made use of jewelry making . Titanium jewelries are suitable for those who are allergic to metals . The jewelry made from this metal can also be easily used in damp environments and pools . It is also used to produce 24-carat gold .
If an alloy is made with gold and one 1% of Titanium , the final grade is about 24 , but the hardness of this alloy is like a 14 - carat gold . Moreover , the alloy’s durability will range from 24-carat gold . Titanium is also used in manufacturer of wrist watches , sculptures , and furniture .
It is not even toxic in large quantities and does not play a specific role in the human body . Eight milligrams of this element is consumed daily by humans . This little amount does not accumulate in the tissues unless the tissues involves silica ( SiO2 ) .
Some studies have found a link between this metal and the yellow fingernail syndrome .
Plants use this element to stimulate the production of carbohydrates under unknown mechanisms . That is why most plants include 1 ppm of this metal .
This amount for food plants is about 2 ppm and for nettles is about 80 ppm .
● It is the ninth most abundant element on earth and the fourth major structural metal .
● The mineral resources of titanium are utile , ilmenite , leucoxene , which are species of ilmenite .
● Major producers of ilmenite and titanium in the world include : Australia, Canada, Norway , South Africa , the United States and Russia . Utile producers include : Australia , Sierra Leone and South Africa . Titanium sponge is produced mainly by : Russia , Kazakhstan , the United States , Japan , Britain and China .
● Titanium and its alloys have been used in the form of bars , ingots , tubes , wires and sections in different industries .
● The density of titanium is about half the density of steel or nickel - based super alloys .
● The price of titanium - while almost four times the price of stainless steel - is comparable to the price of super alloys .
● Titanium is widely expected to be corrosion - resistant . This resistance is often higher than stainless steel in most environments and has extraordinary corrosion resistance in the human body .
● Titanium can be shaped and machined easily , although it has to be considered a reasonable caution .
● Titanium is available in a range of different forms and shapes .
