What is the difference between the pure titanium and titanium alloy, people who understand this industry should all know, in the metal of titanium, titanium plate, titanium bar, including titanium pipe and so on, which are all divided into two types of pure titanium and titanium alloy? However, whether these two kinds of titanium metal have some differences, and what are these differences? Today Zhengzhou Sanhui Trading Co. Ltd. will make a specific summary:
The most remarkable difference between the pure titanium and titanium alloy is that titanium alloy is added such as Al, Mo, Cr, Sn and other chemical substances based on pure titanium, it is precisely because of these chemicals that cause the difference between these two kinds of titanium in the performance. This article is mainly about the analysis of pure titanium in the classification, properties and application.
1. The classification of pure titanium. According to the content of impurity, titanium is divided into high pure titanium (purity over 99.9%) and industrial pure titanium (99.5% purity). Industrial pure titanium has three grades, and they are respectively showed in TA1, TA2, and TA3, the number is larger, the purity is lower.
2. The performance of pure titanium. Ti: 4.507 g/cm3, Tm: 1688 C. have the allotropic transformation, and ≤882.5℃ is α phase of close packed six party structures. ≥882.5℃ is  the β phase of  body centered cubic structure. The intensity of pure titanium is low, but the specific strength is high. In addition, it has also other advantages, such as good plasticity, low temperature toughness, high corrosion resistance. The titanium has good pressure processing properties, but the cutting performance is poor. Titanium can be burnt heated in nitrogen. Therefore, the titanium should adopt argon protection during the heating and welding.
3. The application of pure titanium. The content of impurity plays a very important role in the titanium properties, a small amount of impurities can significantly improve the strength of titanium, so the strength of industrial pure titanium is higher, close to the level of high strength aluminum alloy, and it’s mainly used in the manufacture of petrochemical for heat exchanger, reactor, ships, aircraft skin parts etc..
Through the introduction to the difference between pure titanium and titanium alloy and the pure titanium in the classification, properties and application, I believe that we have a preliminary understanding of this.
