Origin and manufacture of titanium:

Discovered in 1791 by the British William Gregor, the first use of titanium dates back to the beginning of the 20th century, as an additive to cast iron and steel, in the form of ferro-titanium. It is the 22nd element of the periodic table, it has the symbol Ti. It is a stable element which belongs to the family of transition metals such as silver, cadmium… It is the 7th element in order of abundance in the earth's crust and most eruptive or sedentary rocks contain it. However, it is mainly imported from Australia.

The manufacture of titanium requires various complex operations that we will not develop… we will simply say that it is obtained in the form of a sponge from which the excess magnesium chloride is distilled under vacuum at around 1000°C. This sponge is then consolidated by vacuum fusion to obtain ingots or molded parts. These processes explain the cost of this material, which is also why it is also used with other materials in the form of an alloy such as beta-titanium .
