Titanium sits in group 4 of the periodic table and possesses an excellent strength-to-weight ratio. This means the metal is incredibly strong while remaining surprisingly light in weight. As a reactive metal, titanium quickly forms a protective oxide coating (TiO2) in normal air.
This microscopic layer stops the inner metal from rusting and provides exceptional corrosion resistance. In nature, titanium mainly exists in common minerals like rutile and ilmenite. Miners easily find these abundant minerals distributed throughout the Earth’s rocky crust.
The metal shows dimorphism, meaning it can exist in two different crystal shapes. At room temperature, the metal maintains a stable hexagonal alpha crystal form. Above 882 degrees Celsius, it changes its internal structure into a cubic beta form.
Chemically, titanium usually shows an oxidation state of +4 in its most stable compounds. Titanium is totally biocompatible, meaning the human immune system does not reject it. This non-toxic nature makes the metal perfectly suited for sensitive biological and medical environments.
Manufacturers often mix pure titanium with elements like aluminum and vanadium to create alloys. These unique alloys offer enhanced mechanical properties for the most demanding structural applications.
