» Aircraft usages presently accounts for 7% of vanadium market and is growing rapidly—Demand projected to double by 2016
» Aircraft manufacturers using increasing amounts of titanium-vanadium alloy—Boeing's new 787 Dreamliner and the Airbus 380 each contain more than 100 tonnes of the alloy, more than double that in a Boeing 747
» Air traffic is forecast to double over the next 15 years.
Steel and titanium alloys with vanadium are particularly suitable for use in the aerospace industry in airframes, jet engines and other applications. Recent advances have produced vanadium alloys that are both super-light and super-strong. In fact, vanadium-titanium alloys have some of the highest strength-to-weight ratios of any engineered materials.
Vanadium is critical as an alloying element in various aspects of transportation including automotive, aviation and aerospace. The machinability and economic benefits of vanadium steel find it widely used in components such as axles, crankshafts, gears and chassis. In aviation and aerospace, vanadium's strength and thermal stability is utilized in jet engines.
Vanadium foil is used in cladding titanium to steel to make airframes. In this sector, vanadium is irreplaceable as there is no acceptable substitute for Vanadium in aerospace titanium alloys. This is because Vanadium-titanium alloys have the best strength-to-weight ratio of any engineered material on earth. As with steel alloys used in construction, only small amounts are required in order to achieve the desired critical properties for safety and performance.
