alloying
High-strength titanium alloys are alloyed with aluminum and vanadium, and heat resistance is achieved doped molybdenum and aluminum. Most used titanium alloys containing both molybdenum, aluminum, vanadium. Such alloys have a particularly high strength and corrosion resistance. Aluminum is the principal alloying element, it is also important for the titanium alloys, both iron carbon. The second important component is considered molybdenum.
Basic quality
Paramagnetic Titanium alloys have high specific strength demanded by a number of industries. These advantages are particularly valuable in mechanical engineering, aviation, where heat resistance is important, the corrosion resistance in combination with a specific strength. This is also true in the shipbuilding, rocket, railway transport. Some specific structural properties of titanium are of great interest for the food and chemical industries.
