Titanium is a very new material, the metal of the “space age”, not only by the aerospace and aviation industry as the guest of honor. It is also found in civilian medical devices and sports watches.
In the field of watchmaking, titanium is lighter and more resistant to corrosion than watches made of stainless steel. The main advantage of titanium compared to steel is low density, corrosion resistance; white metal watches metal and platinum are now hot. The number of titanium watches is not much compared to steel watches, but we are now seeing more titanium watches than at any time in the past, because watches made of titanium are not only human-friendly and hypoallergenic, but also extremely light, tough and low-key luxury, and more and more in the future.
1、Lightweight
Generally speaking, the density of titanium metal is lower than stainless steel (the density of the former is roughly 4.5g/cm3, the latter density is 8g/cm3), in other words, titanium metal is lighter than stainless steel to wear, and this difference is reflected in the relatively thick case of the dive watch will be more obvious.
2、 high compression resistance and strength
The weight and density of titanium metal is lighter and lower than stainless steel, but take grade 5 titanium metal for example, its strength can reach 1000MPa, which is 5 times of stainless steel. Therefore, the aerospace and aviation industries often use a large amount of titanium as the main material for rockets and airplanes. In addition, the Vickers hardness of titanium metal is generally about 350HV, compared to the hardness of stainless steel is about 150-200HV, which shows that the strength of titanium metal is also higher.
3、 skin-friendly
Some people may be allergic to the nickel content of stainless steel, but titanium because it does not contain nickel, so it will not make the wearer have an allergic reaction – the natural oxide layer on the surface of titanium is not easy to cause allergies in the human body, wearing a natural more at ease.
4、 corrosion resistance
Although today, science has improved the corrosion resistance of stainless steel. But the innate corrosion resistance of titanium metal is also better, want to cause corrosion of titanium metal, unless the watch is taken to be immersed in nitric acid and other strong acids, or basically difficult to see titanium metal will rust, so we often see diving watches labeled as made of titanium, because even if a long time in the salty seawater, titanium watches will not be corroded danger.
5、 low thermal conductivity
The thermal conductivity of the metal on the surface seems to wear us as if there is not much correlation, but imagine two situations: in the winter morning, we have to wear the metal bracelet watch on the wrist of the cold moment, or high temperature of the watch violently worn on the wrist of the hot prickly feeling. At this time titanium is not easy to look too cold or too hot, this point is the benefit of lower thermal conductivity
