In the field of aerospace, titanium has been applied to produce parts like Aerospace Fastener for many years. Commercially pure titanium and titanium alloy as represented by Ti-6Al-4V are mainly used for the air-frame and the engine parts respectively. The demand expansion of titanium has been expected due to realize low fuel consumption of aircraft.
Today, the aerospace industry is the number one customer for titanium alloy products. There are several properties of titanium that make it well suited for Aerospace Fastener that requests the high strength to weight ratio, the resistance to corrosion and the high temperature performance.
Commercial airplanes today, like the AirBusA380 and BoeingB787, use a great deal more titanium than previously engineered aircraft to make Aerospace Fastener. However, the military aerospace industry consumes the largest amount of titanium. Military aircraft, such as the F-22, F/A-18, C-17, F-35 and the UH-60 Black Hawk helicopter, are among some of the military’s assets that use large quantities of titanium to produce Aerospace Fastener.
Not just Aerospace Fastener and frames are made from titanium; aircraft engine manufacturers are also starting to use titanium. The high strength and low density of titanium gives aero-engine manufacturers the high levels of performance they desire. Jet engine and airframe parts need to withstand temperatures from subzero to 600 degrees Celsius, making titanium’s high temperature performance ideal. Engines parts manufactured from titanium include discs, blades, shafts and casings for the front fan to the rear end of the engine.
Titanium has proven to be an invaluable element in many industries, especially for Aerospace Fastener. The Aerospace Fastener industry and the titanium industry are very dependent on each other. As the demand for more planes and more efficient air travel continues to increase, the outlook for the titanium market should hold steady in the future.
At XOT Metals, we carry an adequate and flexible inventory of exotic metals, including titanium, the Ti3AL2.5V ( Gr9) is one normal titanium grade, in order to meet the harsh environments demand in Aerospace Fastener, we made special “Gr9”=TB3 which can get 1400 MPA tensile strength ,even higher. Those titanium special bolts also widely used in helicopter and UAV.
