Titanium was an important structural metal developed in the 1950s. Titanium alloys are characterized by low density and thermal conductivity, high specific strength, good corrosion resistance, non-toxic, non-magnetic, good biocompatibility, and strong surface decoration, which are widely used in aviation, aerospace, chemical industry, petroleum, electric power, medical, construction, sports goods and other fields. Many countries in the world have realized the importance of titanium alloy materials and have developed them successively.
The biggest users of titanium in aerospace are in the west, especially the United States, where 60% of the titanium is used in aviation, while the input of titanium in this field is about 10% in Asian countries such as Japan and China. With the rapid development of Asian aerospace industry in recent years, the consumption of titanium in the aerospace industry will increase accordingly.
From a global perspective, the aviation industry plays a decisive role in the titanium market. Historically, the big cycles in the titanium industry have been closely linked to the rise and fall of the airline industry.
Nowadays, reducing fuel consumption and harmful waste emissions have become one of the main driving forces and directions for the technical progress of the automobile industry. The research shows that lightweight is an effective measure to save fuel and reduce pollution. For every 10% reduction in vehicle quality, fuel consumption can be reduced by 8% to 10%, and exhaust emissions can be reduced by 10%. As for the driving, the acceleration performance is improved after the vehicle is light quantified, as well as the control stability, noise, and vibration of the vehicle.
The preferred way to quantify car lightness is to use lightweight materials with high specific strength, such as aluminum, magnesium, and titanium, instead of traditional automobile materials. In 2009, the amount of titanium used in automobiles worldwide reached 3,000 tons. With the development of the global automobile industry, titanium for automobiles is still increasing rapidly.
Titanium is widely used in many national economic sectors because of its excellent corrosion resistance, mechanical performance, and technological performance. Titanium can be used in chemical production to replace stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials, which is of great importance to increasing production, improving product quality, extending the service life of equipment, reducing energy consumption and costs, and raising labor productivity, etc.
Titanium has been widely used in the medical field. Human implants are special functional materials closely related to human life and health, and titanium is close to the human skeleton and has good biocompatibility and non-toxic side effects on human tissues.
With the development of science and technology and the depletion of land resources, the exploitation and utilization of the oceans have been put on the agenda. Titanium has excellent corrosion resistance to seawater and is widely used in desalination of seawater, ship, marine thermal energy development and seabed resource exploitation.
Titanium is widely used in daily life and can be found everywhere, such as golf heads, bicycle frames, tennis rackets, wheelchairs and spectacle frames. Titanium is also used in sporting goods because of its light weight and high strength, from the earliest tennis rackets and badminton rackets to golf heads, clubs, and racing cars.
