Aerospace
Allti metalsupplies a wide variety of titanium products such as wire, sheet, plate, bar, tube, pipe, disc, ring, screw and more. We dedicated to providing our customers with the best quality, fastest delivery time, lowest price.
The largest user of Titanium material is Aerospace in the past and present .
Titanium and titanium alloy materials are widely used in Commercial and military aircraft,and the amount is directly related to the rise and fall of titanium industry.
For the specific properties associated with the metal included:
- strength to weight ratio
- Reliability,
- corrosion resistance,
- mechanical properties,
- thermal expansion,
- location on the galvanic series ,
The use of titanium in Aerospace has continued to grow day by day.
01.
Commercial aircraft
Because the aircraft engines high temperature and strength characteristics requirement, So the titanium will be the largest and fastest growed in the future. The largest single application of titanium is its use in gas turbine aircraft engines. Titanium’s strength to weight ratio, excellent high temperature characteristics and corrosion resistance naturally lend this metal to aircraft engine applications.Titanium is most commonly the material of choice for engine parts that operate up to 1100 degrees F (593 degrees C).
Twin-aisle planes (e.g., Boeing 747, 767, 777 and 787 and Airbus A330, A340, A350 and A380) use a higher percentage of titanium in their airframes, engines and parts than single-aisle planes (e.g., Boeing 737 and 757 and Airbus A318, A319 and A320).
Moreover, the next-generation commercial aircraft (e.g., Boeing 787 and Airbus A350) .

Military aircraft
The eariest application is 1950’s when titanium was first designed into the Douglas X-3 Stiletto. if then it was widely used in military programs. And Today titanium has also been designed into ballistic applications on a global basis.tani
Then how much titanium will be used for a plane? For example: a Boeing 747 aircraft will reach 35 tons of titanium. Russian Su -27ck, with 8 tons of titanium, The F/A 22 is the true sense of the fourth generation fighter in the world. A F/A – 22 using titanium reached 36 tons of amazing. Accounted for 41% of the total weight.
First titanium accounted for approximately 9% of the weight of a military aircraft to now 90% , F44, F-22, F53,SR-71 in USA, S35, T50, SU-35 in Russian, and J-10,J-11,J-20 in China. So then you could image how much titanium will be used for a plane.
