What is the metal that is widely used in the electrical and electronic industries and has been called the "metal of the 21st century"?

Metals of the 21st Century: . Titanium

Titanium is known as the "space metal" because of its excellent resistance to high and low temperatures, strong acids and alkalis, as well as its high-strength, low-density and stable chemical properties. Titanium can be fused with iron, aluminum, vanadium or molybdenum and other elements into alloys to create a high-strength light alloys, has a wide range of applications in various areas, including aerospace (jet engines, missiles and spacecraft), military, industrial processes (chemicals and petroleum products, desalination and paper), automotive, agri-food, medical (prosthetics, orthopedic implants and dental instruments and fillings), sporting goods, jewelry and cell phones and so on. It is the most popular metal in the 21st century. Titanium, as a new metal material only 50 years of history, however, because it has a series of excellent performance, so that its development speed is very fast, has become the key materials and supporting materials in the field of engineering technology and high technology. At present, the world's developed countries attach great importance to the development and application of titanium, titanium and titanium alloys for a country's national defense, economic and scientific and technological development plays an important role, titanium application amount of how much and the level of development of the titanium industry has become an important symbol of a country's comprehensive strength. From the industrial value of titanium, resource life and development prospects, with the new technological revolution and industrial revolution in depth, titanium will become the iron, aluminum, after the rise of the "third metal", the 21st century will be "titanium century".

The reason why titanium can become the metal of the new century, is determined by its outstanding and unique performance and function, specifically, titanium has the following characteristics and functions:

1, specific strength (tensile strength and specific gravity of the ratio) high. Pure titanium and titanium alloy specific strength are 2.3 times and 3.8 times of mild steel, stainless steel 1.8 times and 3 times. Therefore, titanium is a lightweight and high-strength metal structural material, which is widely used in the aviation field and has become an indispensable structural material. Continuously improve the amount of titanium used in airplanes, has become an important symbol of aircraft upgrading. Such as the YF-12 supersonic long-range interceptor with the amount of titanium, has reached 95% of the weight of the aircraft, the amount of titanium used in civil aircraft is also rising sharply to meet its ever-increasing flight performance. This characteristic of titanium is also used in a large number of general industry and daily necessities, such as high-speed generator ring, steam turbine blades, high-grade bicycles, golf clubs, high-grade eyeglass frames.

2, high and low temperature resistance. Titanium alloy at about 500 ℃ can still maintain good mechanical properties, aerospace engines and high-speed aircraft need to use titanium alloy important parts. What is more valuable is that titanium alloy also has excellent low-temperature resistance, can be -196 ℃ to -253 ℃ low temperature to maintain good elongation and toughness, especially suitable for the space environment on the requirements of the material. Therefore, titanium is also known as "space metal". The United States "Gemini" spacecraft cockpit, almost all made of titanium.

3, strong corrosion resistance. Titanium is a very active metal, but because its surface in the air is easy to form a layer of dense and stable oxide film, is a metal with a strong tendency to passivate, so the corrosion resistance is very strong, is one of the best anti-corrosion materials. Titanium is currently mass-produced, the lowest price, almost completely immune to seawater corrosion of the metal, is the ideal material for ships, ocean engineering. Such as Russia's Typhoon class nuclear submarines each with titanium up to 9,000 tons, not only to increase the depth of diving, but also to improve the speed of navigation; titanium is also used in large quantities for marine oil mining, nuclear power plants and coastal power stations. Therefore, titanium is also known as the "sea metal". Titanium's corrosion resistance, in the chemical field is a great show, now, a variety of titanium equipment has been widely used in chlor-alkali, soda ash, urea, salt and other industries, for these industries has brought significant economic benefits.

4, non-magnetic, non-toxic. Titanium in a large magnetic field will not be magnetized, this feature can make titanium used in magnetron equipment. Titanium ship shells can avoid the explosion of magnetic mines; titanium is non-toxic and good compatibility with human tissue and blood, titanium made of bones and pacemakers not only with the human body's affinity, and will not be affected by the strong magnetic field environment; titanium is also the pharmaceutical industry, the ideal equipment materials. Therefore, titanium is also known as "bio-metal".

5, memory function. Titanium's memory function refers to an alloy of titanium has the ability to remember its own shape. If this alloy is used to make car shells, just use hot water to pour, can be intact as before. Titanium's magic function, make it become special engineering, astronautics, medical treatment in the irreplaceable metal materials.

6, superconductivity. Titanium's superconducting function is an alloy of titanium in the near absolute zero, will show zero resistance, made of wires can pass any large current without heat, no energy consumption, is the best material for the transmission of electricity.

7, hydrogen-absorbing function. Titanium's hydrogen-absorbing function means that titanium has the property of absorbing a large amount of hydrogen, which can store a large amount of hydrogen safely and release it in a certain environment. This in the hydrogen separation, hydrogen purification, hydrogen storage and transportation, the manufacture of hydrogen as an energy source of heat pumps and storage batteries and other aspects of the application of promising, so that hydrogen as a possible alternative to oil "clean" energy applications possible in large quantities.

Titanium's emergence has brought a new era in the use of metallic materials. Titanium's excellent performance makes it a smart metal and all-powerful metal, has been widely used in aviation, aerospace, ships, metallurgy, petroleum, chemical, electric power, electronics, weapons, paper, medicine, construction, automotive and ocean engineering, geothermal engineering, sports, tourism, daily necessities and other fields. The extensive use of titanium for the community has brought great economic benefits, according to statistics, in the chemical industry, metallurgy, vacuum salt, electricity and other fields, each use of a ton of titanium can be more than 100,000 yuan of annual economic benefits. At the same time, the extensive use of titanium, but also become a symbol of the level of development of human civilization, mankind from the Stone Age, Bronze Age, Iron Age, Iron and Steel Age, Aluminum Alloy Age, towards the age of titanium metal, titanium will create new wonders for human society.

Titanium resources are extremely rich, its content accounts for six thousandths of the weight of the earth's crust, can be exploited for years second only to iron, up to five or six thousand years or more. China's titanium resources in the world's first, according to statistics, China's titanium ore reserves is the world's proven reserves of about 64%, which for the development of China's titanium industry and to expand the application of the unique conditions.

Titanium melting technology is complex, difficult processing, high technology content. At present, only the United States, Russia, Japan, China and a few other countries in the world to master the complete industrial production technology. China's titanium processing industry has more than 40 years of history, Baoji Titanium Co., Ltd. is China's only professional titanium processing materials production and research base, it is by China's titanium processing materials production giant - Baoji Nonferrous Metals Processing Plant, the joint Northwest Nonferrous Metals Research Institute, China Nonferrous Metals Import and Export Corporation of Shaanxi Province, Central South University, Northwestern Polytechnical University, Shaanxi Province, Huaxia Property Company *** with the launch of the establishment of industrial advantages, scientific research advantages, market advantages, closely integrated with production, learning, research and science, industry, trade in one, and become today's China's titanium industry development level of representatives, known as "China's titanium city". At present, the company's production of titanium and titanium alloy processing material products each year accounted for more than 85% of the country's total output and sales of titanium, and 36 major products using the international advanced level of technical standards, "Baoji titanium" in the international market has become a high-profile brand products.

China's titanium industry is entering a period of rapid development, unique resource conditions, a wide range of applications, the country's strong support for the development of China's titanium industry has laid a solid foundation. We can say with confidence that in the near future, China will become the world's titanium industry powerhouse, to make greater contributions to the development of human society.
