Application Of Titanium Alloy In Computer Hardware

Application Of Titanium Alloy In Computer Hardware


The computer hard disk disc market has great potential and is developing rapidly. Among the many materials that can be used in the computer industry, titanium has gradually become an ideal material for key components such as hard disk drives due to its unique advantages. With the rapid development of the information industry and the increasingly fierce market competition, the application prospects of titanium in the computer field are becoming more and more broad.


1. Hard Disk Disc: A “Lifter” For Storage Performance


Computer hard disk discs have extremely high material performance requirements, and titanium alloys (mainly Ti-3Al-2.5V) have shown many advantages over traditional materials in this field. Compared with general-purpose aluminum alloy and glass hard disks, titanium alloy hard disk discs have higher strength. This feature allows the thickness of the disc to be reduced, thereby increasing the storage density and speed. At the same time, the surface finish of the titanium alloy disc is extremely high, which can effectively reduce the distance between the read and write head and the disk, and further improve the storage density. In addition, titanium discs also have distinctive characteristics such as high damage tolerance and high surface hardness, which provide a strong guarantee for the stable operation and long-term use of hard disks.


2. Laptop Case: A “Fusion” Of Beauty And Performance


In the field of notebook computers, titanium also shines brightly. In January 2001, Apple Computer (APPLE) in the United States launched the innovative Titanium PowerBook G4 laptop computer, which uses Grade 1 industrial pure titanium to make a shell. This titanium shell computer not only has a beautiful appearance, but also performs well in performance. Compared with magnesium, titanium has higher tensile strength (106.3GPa for titanium and 44.4GPa for magnesium) and lower thermal conductivity (17W/mK for titanium, only 1/9 of 159W/mK for magnesium). Therefore, while the titanium shell is thin-walled, it can maintain sufficient strength, effectively suppress the diffusion of heat from the hardware, prevent the bottom surface from overheating, and bring users a more comfortable experience.


The ThinkPad A-series and T-series laptop cases produced by Lenovo also use titanium-based composite materials. The application of this material not only improves the strength and seismic resistance of the chassis, but also makes the computer thinner and more portable, meeting the dual needs of modern users for the portability and durability of notebook computers.


3. Industry Promotion: The “New Driving Force” For Innovation And Development


The American Timet company keenly captured the huge potential of titanium in the computer field and invested 5 million US dollars to establish an internal organization of titanium discs. As early as 1998, the company has carried out new development on small-scale microcomputer drive components. Titanium for hard drives has brought significant economic benefits and development opportunities to Timet.


In terms of production technology, the discs mostly use precision cold-rolled titanium or titanium alloy technology. In order to further improve the performance of the disc, the surface of the disc can be hardened by plasma nitriding, plasma carburizing or plasma carbon-nitrogen co-infiltration, and a layer of titanium nitride or titanium boride hard coating can also be sprayed. These treatments effectively enhance the wear resistance and corrosion resistance of the disc, and extend the service life of the hard disk.


With its excellent performance, titanium alloy has been widely used in computer hardware such as computer hard disk discs and notebook computer housings, and has promoted technological innovation and development in related industries. With the continuous progress of information technology, the application of titanium alloy in the field of computer hardware will surely become more extensive and in-depth.
