Application Of Titanium In Aerospace Field

2024-01-05 18:00:06

   Titanium used in aerospace is concentrated in the western countries, especially the United States, 60% of titanium materials are used in this field. Asian countries, Japan and China have invested about 10% of it in this area. But with the rapid development of Asian aerospace in recent years, the consumption of titanium in the field of Aerospace will increase accordingly. From a global point of view, the aviation industry plays a decisive role in the market. Historically, the large cycle of the titanium industry is closely related to the warmth and coldness of the aviation industry.

  In 2011, global titanium production reached 148,000 tons, including about 64,000 tons of commercial aviation , the future global economic growth demand for air transport is still huge, estimated in the next 20 years about 30,000 new aircraft demand, at the same time, new aircraft demand for titanium is higher than the old aircraft, is expected to fly commercially within 20 years. The average demand for materials for aircraft will reach 40 tons per rack, and it is estimated that the global commercial aviation industry will increase the demand for materials by about 1.2 million tons in the next 20 years, with an annual compound growth rate of about 17%, with an average annual increase of 60,000 tons of titanium demand, and the field of civil aviation materials will show rapid growth. There will also be new opportunities in the field of military aviation; new demands in the field of military aviation are expected to emerge because of the global geopolitical tension and the increase in military expenditures of countries around the world.

  Civil aircraft

  The main uses of titanium alloys in aircraft are as follows:

  Reduce structural weight and improve structural efficiency: Advanced combat performance (e.g. supersonic aircraft) requires aircraft to have a relatively low structural weight coefficient (i.e. aircraft structural weight / normal take-off weight), while titanium alloy has a strength close to medium-strength steel but low density characteristics, instead of structural steel and high-temperature alloy, which can be greatly reduced. Lightweight construction also saves money; for example, statistics show that the cost of using an aircraft engine can be reduced by about $220-440 per kilogram of weight reduction.
