Now more common to use titanium hard disk on TC Titanium the market specifications: diameter 95mm thickness 0.8mm 0.635mm or look hardness 14700MPa Young's modulus 660GPa maximum operating temperature of 700 ℃; flatness <10μm roughness Ra <0.8nm disc used Production technology for precision cold-rolled titanium or more titanium rod and titanium alloy, the outer disc by plasma nitriding, plasma nitriding or plasma nitrocarburizing hardened disposal, the disc outer layer of titanium nitride may also be sprayed or titanium boride hard coat layer.
develop rapidly. 1998 world production of about 450 million discs. Analysts predict a huge market computer's hard disk. Hard disk production by 10% -15% annual growth rate. It is estimated that, with the intense competition and the rapid development of information industry market, the titanium used in computers will have a better market.
So titanium used in personal computers, mobile phones and other areas is increasing. Titanium used on a computer is mainly used as computer housings, and hard disks. Because titanium has a light weight, no metal allergy can be recycled, and many other fine features. Not only improves the strength and seismic performance chassis, IBM in May 2000 the company announced that its new ThinkPad notebook computer casings titanium matrix composites. A series of ThinkPad computers (such as A20p and T Series (T20 chassis was used as titanium matrix composites. And the computer can be thinner and lighter.
Fujitsu pioneered the use of titanium (99.5% manufacture of small A5 size, 890 grams lightweight laptop case. 1999 The company has a titanium rod and titanium alloy (on INTERTOPCX300 housing in the laptop. So in the realization of titanium as Titanium round bar housing data thinned while maintaining strength, tensile strength than titanium case primarily as computer data much higher magnesium (magnesium-titanium 106.3GPa titanium 44.4GPa thermal conductivity (17W / mK only magnesium (159W / mK one-tenth. suppress diffusion of heat from the hardware, etc., to prevent the underside of the fever, especially due to the appearance of excellent corrosion resistance of titanium, the appearance of the coating becomes relatively simple disposal.

Titanium is an important structural metal in the 1950s developed, titanium due to a high specific strength, good corrosion resistance,Titanium filler wire  and high heat resistance, are widely used in various fields. Many countries recognize the importance of titanium alloy, have their research and development, and has been applied. Titanium is the periodic table ⅣB element, look like steel, melting point up to 1 672 ℃, the case of refractory metals. Titanium content in the crust than the rich, far higher than common metals Cu, Zn, Sn, Pb and the like. Our resources are very rich in titanium, vanadium-titanium magnetite large only found in Panzhihua region, associated titanium reserves of about 420 million tons, close to the foreign total proven reserves of titanium. Titanium-use can be divided into heat-resistant alloys, high-strength alloys, titanium bar stock corrosion resistant alloy (titanium - molybdenum, titanium - palladium alloys, etc.), low-temperature alloys and special features alloy (Ti - Fe hydrogen storage materials and titanium - Ni shape memory alloys) .

The application of titanium in the aerospace industry in the

It referred to as spatial metal and titanium metal universe, which is due to the low proportion of titanium, second only to aluminum, but titanium hardness and hardness of steel but almost. Only current application of titanium alloy, in astronautics reached 1,000 tons. Besides there are very fine titanium powder, it is also a good fuel rocket launcher
The proportion of Titanium Flange Screw  is low, and has good heat cold resistance. When the supersonic aircraft, its wings can reach temperatures of 500 ℃. If relatively heat-resistant aluminum alloy wing, one to twenty-three Baidu will be too much, then there must be one kind and light, and tough, and high temperature of the material instead of aluminum, and titanium just to meet these Claim. Titanium can withstand the test of minus 100 ℃, at such low temperatures, titanium still has good toughness, brittle hair will not affect the physical properties.
