1. Aerospace field
Titanium countries in the aerospace industry are concentrated in Western countries, especially in the United States, and 60% of titanium materials are used in this field. Asian countries, Japan and China have invested about 10% of titanium in this field. However, with the rapid development of Asian aerospace in recent years, the consumption of titanium in the aerospace industry will increase. From a global perspective, the aviation industry plays a decisive role in the titanium market. Historically, the large cycle of the titanium industry has been closely related to the cold and warm of the aviation industry.
2. Civil aircraft
(1) Reduce structural weight and improve structural efficiency
(2) Meet the requirements for use of high temperature parts
(3) Meet the requirements for matching with the composite structure
(4) Meet the requirements of high corrosion resistance and long life
3. Military weapons
The development and procurement of military weapons is constantly moving towards a light and flexible direction. In order to meet the combat performance requirements of fighters, in addition to advanced design techniques, materials with excellent performance and advanced process manufacturing techniques must be used. The large selection of titanium alloys and the improvement of the application level of advanced titanium alloys are one of the important measures.
Since the 1960s, the amount of titanium in foreign military aircraft has increased year by year. The amount of titanium alloy used in various advanced military fighters and bombers designed in Europe and America has been stabilized at more than 20%, and the proportion of titanium used in new models is increasing. Upgrade.
4, the car
Reducing fuel consumption and reducing harmful waste (CO2, NOX, etc.) emissions have become one of the main driving forces and directions for technological advancement in the automotive industry. Studies have shown that lightweighting is an effective measure to save fuel and reduce pollution. For every 10% reduction in the quality of a car, fuel consumption can be reduced by 8%-10% and exhaust emissions can be reduced by 10%.
In terms of driving, the car’s lightweight performance is improved, and vehicle control stability, noise, and vibration are also improved. From the perspective of collision safety, after the vehicle is lightened, the inertia is small during the collision and the braking distance is reduced.
The preferred way to reduce the weight of a car is to replace traditional automotive materials (steel) with lightweight materials such as aluminum, magnesium, and titanium. In 2009, the amount of titanium used in automobiles worldwide has reached 3,000 tons. Titanium has been used in racing cars for many years. At present, almost all of the cars are made of titanium. The titanium used in Japanese cars has exceeded 600 tons. With the development of the global automotive industry, titanium for automobiles is increasing rapidly.
5. Medical industry
Titanium has a wide range of applications in the medical field. Titanium is close to human bones and has good biocompatibility and no toxic side effects on human tissues. Human implants are special functional materials that are closely related to human life and health. Compared with other metal materials, the advantages of using titanium and titanium alloy are as follows:
1 light weight; 2 low modulus of elasticity; 3 non-magnetic; 4 non-toxic; 5 corrosion resistance; 6 high strength, good toughness.
The amount of titanium alloy used in surgical implants is increasing at a rate of 5%-7% per year. Femoral head, hip joint, tibia, skull, knee joint, elbow joint, shoulder joint, metacarpophalangeal joint, jaw bone and heart disc, kidney disc, vasodilator, splint, prosthesis, made of titanium and titanium alloy Hundreds of metal parts, such as fastening screws, have been transplanted into the human body and have achieved good results, which has been highly evaluated by the medical community.
6. Chemical industry
Titanium has excellent corrosion resistance, mechanical properties and process properties and is widely used in many sectors of the national economy. Especially in chemical production, titanium is used instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is of great significance in increasing production, improving product quality, extending equipment life, reducing consumption, reducing energy consumption, reducing costs, preventing pollution, improving working conditions and increasing labor productivity.
7. Ocean Engineering
With the development of science and technology and the depletion of terrestrial resources, human development and utilization of the ocean has already been mentioned on the agenda. Titanium has excellent corrosion resistance to seawater and is widely used in seawater desalination, shipbuilding, marine thermal energy development and seabed resource exploitation.
8, daily life
Titanium is widely used in daily life, and it can be described as ubiquitous. For example, golf clubs, bicycle frames, tennis rackets, wheelchairs, and eyeglass frames are all applied to titanium.
Titanium has been used in sporting goods for its light weight and high strength. It has gradually expanded from the earliest tennis rackets and badminton rackets to golf clubs, clubs and racing cars.
