Applications of titanium alloys in daily life

Titanium applications in everyday life include cameras, eyeglass frames, watches, cookware and tableware, golf heads, decorative items, and more. The camera industry uses titanium, starting with the shutter curtain. Nippon Optical Industry Co., Ltd. (Nikko) used pure titanium shutter curtains on Nikon SP and Nikon F in 1959 to increase the shutter speed. In 1971, Nikko Company used titanium to make the viewfinder frame on the F2 camera to increase the bounce speed of the viewfinder in front of the shutter curtain at the moment of exposure. In 1978, Nikko Company first used titanium to make camera exterior spectacle frames. Titanium mainly includes pure titanium, Ti12xr, Ti-3AI2.5V, TiNi alloy and P titanium alloy. Its advantages are corrosion resistance, light weight and non-discoloration. It is made of titanium alloy. The weight of the spectacle frame is only about 12g, making it more comfortable for people wearing spectacles. Titanium will not corrode after interacting with human sweat, and will not cause allergic reactions on human skin. China began producing titanium glasses in 1991 and has become the world's largest supplier of titanium glasses. Although the glasses frame is small, the manufacturing process is not simple and highly technical. A pair of metal spectacle frames usually consists of 21-26 parts of the titanium spectacle frame shown in Figure 226. These parts are mainly spectacle legs, frames, hinges, locking blocks, nose pads and screws.

The amount of titanium must account for more than 90% of the total weight of the spectacle frame. Except for the tips of the temple legs, hinge screws, washers and crown brackets, the frame should mainly be made of titanium, and the frame material must not contain nickel (nickel will cause some allergic skin reactions).

Titanium watches are lightweight, corrosion-resistant, and non-magnetic. Titanium watch cases will not produce allergic reactions when in contact with the human body, which is an important advantage that distinguishes them from stainless steel watch cases. Titanium as a watch material started from high-end waterproof and sports watches with timing function. From the 1970s to the early 1980s, Omega launched a waterproof sports watch (Figure 27); Hoya launched a sports watch with a timing function; WC launched a waterproof sports watch with a timing function. At present, titanium watches It has been transformed from high-end watches to popular watches. The titanium materials used include industrial pure titanium, TI6A4V and titanium alloy Ti-15-3-3-3.

Titanium is a kitchen metal material that neither rusts nor is harmless to the human body. Titanium can be used to make cooking utensils and tableware such as woks, kitchen knives, scissors, spoons, forks, and containers. Titanium pots do not rust and are resistant to corrosion by salt, acid, vinegar, alkali and other foods and additives. They have a long service life. Titanium has a small heat capacity and heats up quickly, which is conducive to energy saving. T10-23 titanium alloy is the best tool material. It not only has high strength, but also has good plasticity, which is beneficial to profiling machines and bed forming. The tools it processes are very sharp. Beijing Knife and Scissors Factory has developed a titanium fruit knife, using a 2mm thick T6A14V alloy plate. After stamping the blade, drilling, grinding and polishing the blade, and installing the handle surface into titanium, it can be used as cutlery, forks, spoons and other tableware. After surface treatment, the titanium knife can turn golden yellow and look very noble. The thermal conductivity of titanium is lower than that of aluminum and steel, so it will not burn your mouth when heated.
