Performance and use of titanium alloy rod
As a stable metal, titanium alloy rod has the characteristics of high hardness, low density and good corrosion resistance. Because of these advantages of titanium, we will combine titanium with other metals to make titanium alloy rod, which not only has the original characteristics of titanium, but also has some new characteristics in it.
Titanium alloy rod has high strength, low density and good mechanical properties, corrosion resistance, high stability, etc, but the more stable metal, processing is more difficult, so in the production process of titanium alloy rods is more complex, high cost, so the earliest titanium alloy rod is mainly used in aircraft engine components, and rocket and missile flight parts and so on, In addition, titanium rods are mainly used in the military, scientific research, to make some parts of high strength, corrosion resistance. With the continuous development of science and technology, the cost of titanium alloy rod has been reduced a lot, and it can be used in industry, construction and civil use. For example, titanium wheel bolts and nuts processed by titanium alloy rod are more and more recognized because of their strong corrosion resistance. As the high quality performance of titanium alloy rod is widely recognized and the production technical ability level is increasingly improved, the range of titanium rod products will be more and more widely used in the future.
