Application of titanium rods and titanium materials in the field of information technology
basic industry. Generators, motors, power transmission and transformation equipment in the electric power industry require a large amount of copper, aluminum and titanium alloys. A large amount of copper, aluminum, lead, zinc, magnesium and their alloys are needed in the manufacture of trains, automobiles, ships, airplanes and other means of transportation in the transportation industry. Various alloy steels, superalloys, and precision alloys in the iron and steel industry contain nickel, cobalt, tungsten, molybdenum, titanium, vanadium, niobium, rare earth metals, etc. Aluminum or magnesium is also required as a deoxidizer for steelmaking. Machining is inseparable from carbide tools. Instrumentation, control equipment, electronic components, etc. consume a large amount of titanium and titanium alloy processing materials, silicon materials, elastic materials, and precious metal contact materials. Communication equipment, cables and wires in the communication industry use a large amount of copper, aluminum, lead, zinc, tin, gold, silver and other titanium rods. In the electronics industry, copper, aluminum, tin, gold, silver, platinum group metals, and high-purity silicon, germanium, gallium, indium, arsenic, beryllium, tantalum, niobium, etc. are the main materials. Microelectronics technology based on integrated circuits mainly relies on semiconductor materials. Rare earth metals have been widely used in petroleum, chemical, glass, ceramics, leather, textile and other industries.
Defense industry and high-tech industry. From conventional weapons such as guns, cannons, airplanes, and ships to advanced weapons such as atomic bombs, hydrogen bombs, missiles, and rockets; electronic computers, large-scale integrated circuits, nuclear power plants, high-energy radio waves, superconducting technology, aerospace and artificial intelligence technology, bioengineering, etc. High and new technologies require titanium and titanium alloys, and the requirements and demands are getting higher and higher.
Titanium Bar for Electron Industry, titanium alloy is an important part of modern materials among the three pillars of contemporary civilization, energy, information technology and materials, and has a very close relationship with energy and information technology. , Indispensable basic materials and important strategic materials for the development of science and technology. Agriculture, civil industry, basic industry, national defense industry, and high-tech industry are all inseparable from titanium and titanium alloys.
Agriculture. Pesticides, agricultural rare earth trace fertilizers, agricultural tractors, diesel engines, drainage and irrigation equipment, etc. consume a large amount of titanium rods and their compounds or alloys in the production or manufacture.
Civilian industry. Toothpaste cartridges, door locks, keys, cooking utensils, light bulbs, bicycles and a large number of household appliances and air conditioners that are used in people's daily life, as well as the rapid development of cans and flexible packaging in recent years, all require titanium and titanium alloys. Demand is rising sharply.
The application of Titanium Bar for Electron Industry in personal computers, mobile phones and other fields is increasing day by day. Titanium is mainly used in computers as computer casings and hard disk platters.
Titanium alloys (mainly Ti-3Al-2.5V) for computer hard disks have more advantages than general-purpose aluminum alloy and glass hard disks, such as high strength, reduced disk thickness, increased storage density and speed, and smooth appearance. High, can reduce the distance between the read-write head and the disk, and increase the storage density. Titanium discs also have the characteristics of high damage tolerance limit and high surface hardness.
A titanium disc internal organization was built with an investment of 5 million US dollars by the Timet Company of the United States. In 1998, small-scale new developments were carried out on microcomputer drive components, and titanium used for hard disks will bring great benefits to Timet. At present, the specifications of titanium hard drives commonly used in the market are: diameter 95mm, thickness 0.635mm or 0.8mm, surface hardness 14,700 MPa, Young's modulus 660GPa, maximum working temperature 700°C; flatness <10μm, roughness Ra <0.8nm, the production technology of the disk is mostly precision cold-rolled titanium or titanium rod and titanium alloy, the surface of the disk can be hardened by plasma nitriding, plasma carburizing or plasma carbonitriding, and the surface of the disk can also be hardened Spray a layer of titanium nitride or titanium boride hard coating.
In 1998, the output of discs in the world was about 450 million discs. Analysts predict that there is a large market for computer hard disk platters. Hard disk production is growing at a rate of 10% to 15% per year. It is estimated that with the rapid development of the information industry and fierce competition in the market, there will be a good market for titanium used in computers.
Titanium has many excellent properties such as light weight, no metal allergies, and recyclable utilization. Not only has the strength and shock resistance of the casing been improved, IBM announced in May 2000 that its new ThinkPad notebook computer casing uses titanium-based composite materials. ThinkPad computer A-series (such as A20p) and T-series (such as T20) casings use titanium-based composite materials, and can make computers thinner and lighter.
Japan's Fujitsu Corporation took the lead in using pure titanium (99.5%) to make a small A5 size, 890g lightweight notebook computer casing. At present, the company has used titanium rods and titanium alloys on the notebook computer (INTERTOPCX300) casing. Therefore, titanium is used as the casing material in the realization Thin-walled while maintaining strength, the tensile strength of titanium is much higher than that of magnesium, which is mainly used as a material for computer casings (magnesium is 44.4GPa, titanium is 106.3GPa), and the thermal conductivity of titanium (17W/m.K) is only magnesium One-tenth of (159W/m.K). Suppresses the heat diffusion from the hardware, etc., and prevents the bottom surface from heating, especially because the titanium surface has excellent corrosion resistance, and the coating treatment on the surface becomes relatively simple.
