The GR1 titanium tube is malleable. The elongation of high purity titanium can reach 50 ~ 60% and the reduction of cross section can reach 70 ~ 80%. Although the strength of high purity titanium is low, the mechanical properties of pure industrial titanium can be significantly enhanced by the addition of a few impurities and alloying elements. This means that the industrial pure titanium tube, as long as it contains a small amount of interstitial impurities and other metal impurities, can make it both high strength, and the appropriate plastic. The specific strength (strength to weight ratio) of industrial pure titanium tubes is very high in metal structural materials. It is as strong as steel, but its weight is only 57% of that of steel. In addition, titanium tube is very strong heat resistance, in the 500℃ atmosphere can still maintain good strength and stability. Titanium tube also has good low temperature resistance, even at -250℃ ultra-low temperature, it still has high impact strength, can withstand high pressure and vibration. Another notable feature of industrial pure titanium tube is its strong corrosion resistance, which is due to its special affinity to oxygen, and the formation of a dense oxide film on its surface, which can protect titanium from medium corrosion. Therefore, titanium has good stability in acidic, alkaline, neutral salt aqueous solution and oxidizing medium, and better corrosion resistance than existing stainless steel and other non-ferrous metals. The application range of industrial pure titanium pipe is very wide. At present, industrial pure titanium pipe is not only very important in aerospace and aviation industries, but also has been widely used in many industrial sectors such as chemical industry, petroleum, light industry and power generation. Because pure industrial titanium tube has light weight, great strength, strong heat resistance, corrosion resistance and many other excellent characteristics, known as the "future metal", is a very promising development of a new type of structural material.
