1, the aerospace field with titanium in the big countries concentrated in the West, especially the United States, 60% of the titanium are applied to this field. Asian countries, Japan and China in this field in the amount of titanium input are about 10%. But in recent years with the rapid development of Asian aerospace, titanium consumption in the field of aerospace will grow. From a global perspective, the aviation industry plays a decisive role in the titanium market, from a historical point of view, the titanium industry cycle is closely related to the aviation industry.
2, civil aircraft
(1) reduce structural weight, improve structural efficiency
(2) meet the high temperature parts of the use of the requirements
(3) meet the requirements of matching with the composite structure
(4) meet the requirements of high resistance to corrosion and long service life
3, military aircraft
Military weaponry Development and procurement continue to lightweight, flexible direction, in order to meet the combat performance requirements of fighter aircraft, in addition to the use of advanced design technology, but also must be used in the amount of materials with excellent performance and advanced manufacturing technology. A large number of titanium alloys, improve the level of application of advanced titanium alloys is one of the important measures.
Since the 1960s, the amount of titanium in foreign military aircraft has increased year by year, and the amount of titanium alloy used in various advanced military fighters and bombers designed in Europe and the United States has stabilized at more than 20%, and the proportion of titanium used in the new models is being significantly increased.
4, automotive
Reducing fuel consumption and reducing harmful waste (CO2, NOX, etc.) emissions has become one of the main driving forces and directions of technological progress in the automotive industry. Studies have shown that lightweighting is an effective measure to achieve fuel savings and reduce pollution. For every 10% reduction in automobile mass, fuel consumption can be saved by 8%-10%, and exhaust emissions can be reduced by 10%.
In terms of driving, acceleration performance is improved after lightweighting, and vehicle control stability, noise and vibration are also improved. From the collision safety considerations, automobile lightweight, collision inertia is small, braking distance is reduced.
The preferred way of automotive lightweight is to use high strength lightweight materials, such as aluminum, magnesium, titanium, etc. to replace the traditional automotive materials (steel). 2009 global automotive titanium volume has reached 3000 tons. Titanium in the application of racing has been many years of history of the current racing almost all use titanium, Japan's automotive titanium has more than 600 tons, with the development of the global automotive industry, automotive titanium is still increasing rapidly.
5, the medical industry
Titanium has a wide range of applications in the medical field. Titanium and human bone close to the human tissue has good biocompatibility, no toxic side effects. Human implant is closely related to human life and health of the special functional materials. Compared with other metal materials, the advantages of using titanium and titanium alloys are mainly the following:
1 Light weight; 2 Low modulus of elasticity; 3 Non-magnetic; 4 Non-toxic; 5 Corrosion resistance; 6 High strength and good toughness.
Titanium alloy usage in surgical implants is growing at a rate of 5-7% per year. The use of titanium and titanium alloy manufactured femoral head, hip joints, humerus, skull, knee joints, elbow joints, shoulder joints, metacarpophalangeal joints, jawbone, as well as the heart discernment membrane, renal discernment membrane, vasodilator, splints, prostheses, tightening screws and so on hundreds of metal parts transplanted into the human body, and achieved good results, by the medical profession to give a high evaluation.
6, the chemical industry
Titanium has excellent corrosion resistance, mechanical properties and process performance, is widely used in many sectors of the national economy. Especially in chemical production, titanium instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is to increase production, improve product quality, extend the service life of equipment, reduce consumption, reduce energy consumption, reduce costs, prevent pollution, improve labor conditions and improve labor productivity are very important.
7, marine engineering
With the development of science and technology and land resources are becoming increasingly depleted, human development and utilization of the sea has been mentioned on the agenda. Titanium has excellent corrosion resistance for seawater, a large number of desalination, ships, ocean thermal energy development and undersea resource extraction and other fields.
8, daily life
Titanium is widely used in daily life, can be said to be ubiquitous, such as golf heads, bicycle frames, tennis rackets, wheelchairs, eyeglass frames, etc. will be applied to titanium.
Titanium, with its lightweight and high strength characteristics, has been used in sporting goods from the earliest tennis rackets and badminton rackets to golf heads, clubs and racing cars.
In 2008, China's sports and leisure accounted for 13% of the total consumption, of which the amount of titanium used in golf heads and clubs alone exceeded 1,000 tons. Bicycle frames made of titanium alloy are also popular, there are nearly 50 price companies produce titanium bicycles, the United States has long been the largest producer and consumer of titanium bicycles.
Titanium's lightweight features are also used in eyeglass frames, and titanium is not easy with the skin allergies, and titanium surface by anodic treatment can be a brilliant color, so from the early 1980s began to be used in the frame.
Expanded Information
Titanium is considered a rare metal due to the fact that it is dispersed in nature and difficult to extract. However, it is relatively abundant, ranking tenth among all elements. The main ores of titanium are ilmenite and rutile, which are widespread in the earth's crust and lithosphere. Titanium is also found in almost all living things, rocks, water and soil.
Titanium is extracted from the major ores by the Kroll or Hunt method. The most common compound of titanium is titanium dioxide, which is used to make white pigments. Other compounds include titanium tetrachloride (TiCl4), which is used as a catalyst and in the manufacture of smoke screens for air cover, and titanium trichloride (TiCl3), which is used to catalyze the production of polypropylene.
