Gr12 titanium is an important structural metal developed in the 1950s. Titanium alloy has the characteristics of low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, weldable, biocompatible, and strong surface decoratability, etc. It is widely used in the fields of aviation, aerospace, chemical industry, petroleum, electric power, medical treatment, construction, and sporting goods. Many countries in the world have recognized the importance of titanium alloy materials, successively research and development, and practical applications.
Automobile industry
Reducing fuel consumption and harmful waste (CO2, NOX, etc.) emissions has become one of the main driving forces and directions for technological progress in the automotive industry. Studies have shown that lightweighting is an effective measure to achieve fuel saving and pollution reduction. 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, the acceleration performance of automobiles 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 automobile 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 cars has been many years of history of the current car 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.
The advantages of using titanium in automobiles include: reducing weight and fuel consumption; improving power transmission effects and reducing noise; reducing vibration and component load; improving the durability of the car and environmental protection.
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 alloys are mainly as follows: 1 light weight; 2 low modulus of elasticity; 3 non-magnetic; 4 non-toxic; 5 corrosion resistance; 6 high strength and good toughness. The use of titanium alloys 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 other hundreds of metal parts transplanted into the human body, achieved good results, was given a very high evaluation by the medical profession.
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.
Titanium has become one of the main anti-corrosion materials in chemical equipment and has established its corrosion-resistant status in chemical installations. As an ideal material for chemical equipment, titanium has also attracted more and more attention from engineers and technicians.
After years of promotion, titanium and its alloys have been widely used as an excellent corrosion-resistant structural materials in chemical production. At present, the application of titanium equipment has been expanded from the initial soda ash and caustic soda industry to chlorate, ammonium chloride, urea, organic synthesis, dyestuffs, inorganic salts, pesticides, synthetic fibers, fertilizers, and fine chemical industry, the type of equipment has been developed from small-scale, monomerization to large-scale, diversification.
The survey results show that titanium heat exchanger accounted for 57%, titanium anode accounted for 20%, titanium container accounted for 16%, and others accounted for 7%. In the chemical industry to "two alkali" is the main chemical equipment, titanium heat exchangers in the largest amount.
In recent years, China's titanium production technology to improve rapidly, aerospace titanium, military titanium, automotive titanium and other growth is very rapid, especially in the field of aerospace, there is a tendency to catch up with the chemical titanium. Overall, chemical titanium technology content is small, low value-added products, chemical titanium proportion will inevitably decline gradually.
Marine engineering
With the development of science and technology and the depletion of land resources, human development and utilization of the ocean has been put on the agenda. Titanium for seawater has excellent corrosion resistance, a large number of applications in the field of desalination, ships, ocean thermal energy development and seabed resource extraction.
As early as the 1960s, China has begun the application of titanium and titanium alloys in ships and marine engineering equipment research, and has done a lot of work, has basically formed a number of grades, different properties, varieties and specifications of the ship with a complete system of titanium alloys.Due to the characteristics of titanium and titanium alloy itself, it has unique advantages in the application of ships and marine equipment, and thus is widely used in nuclear submarines, deep submarines, atomic energy icebreakers, hydrofoils, hovercraft, minesweepers and propellers, seawater piping, condensers, heat exchangers and so on.
In the application of ships, China's ships with titanium is very small, accounting for the proportion of the total weight of the ship is not more than 1%, ships and marine equipment with titanium and titanium alloy field has great potential for development. In addition, in seawater desalination and coastal power station, due to China's current seawater desalination and coastal power station market demand is huge, in the case of further reducing the cost of titanium alloy and improve the stability of product quality, titanium market applications will be very broad prospects.
Daily life
Titanium is widely used in daily life, and can be said to be everywhere, such as golf heads, bicycle frames, tennis rackets, wheelchairs, eyeglass frames and other applications of titanium.
Titanium with its lightweight, high strength characteristics in sporting goods applications, from the earliest tennis racket, badminton racket gradually expanded to the golf head, clubs and racing cars, etc. In 2008, China's sports and leisure accounted for 13% of the total consumption of titanium, of which the amount of titanium used in the golf head and clubs alone is more than 1,000 tons. Titanium alloy made of bicycle frames are also quite popular, there are nearly 50 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 to allergic to the skin, and titanium surface by anodic treatment can have brilliant colors, so from the early 1980s began to be used in frames.
In recent years, the application of titanium in human daily life has been expanding and developing rapidly, and the application technology has become more mature and perfect. In the application of titanium in daily life, the United States and Japan are in the forefront.
