Alloying
High-strength titanium alloys are alloyed with vanadium and aluminium, while heat resistance is achieved by molybdenum + aluminium alloying. Most titanium grades used contain molybdenum, aluminum, and vanadium at the same time. Aluminum is the major alloying element, and is as important to titanium alloys as carbon is to iron. Titanium and its alloys are paramagnetic, can be welded well and have other advantages that are important in technical fields. For example, such as machine building, where heat resistance and specific strength combined with corrosion resistance are needed, aircraft construction, shipbuilding, rocket production, food processing, chemical, pulp and paper industries.
