TA1 titanium alloy is a proprietary grade of Wugang Technology. Titanium alloy has three matrix structures: industrial pure titanium is divided into three grades of TA1, TA2 and TA3 according to the content of impurities. The interstitial impurity elements of these three industrial pure titanium It is gradually increasing, so its mechanical strength and hardness also increase step by step, but the plasticity and toughness decrease accordingly. The industrial pure titanium commonly used in industry is TA2, because of its moderate corrosion resistance and comprehensive mechanical properties. TA3 can be used when higher strength requirements are required. TA1 can be used when better formability is required. TA1, TA2 and TA3 in the national standard correspond to Gr0, Gr1 and Gr2 in this UNS. When the content ω is 0.08%, the hydrogen content ω is 0.0009%, and the nitrogen content ω is 0.0062%, it has good low-temperature toughness and high low-temperature strength, and can be used as a low-temperature structural material below -253°C.

The chemical composition of TA1 and TA2 grades should comply with the corresponding provisions of GB3620-83. The chemical composition of cladding metal should comply with the provisions of JISH4600. The United States researched and put into industrial production of composite materials much earlier than my country. However, in ASTMA263 "Specification for Corrosion-resistant Chromium Steel Clad Steel Plate", ASTMA264 "Specification for Chromium-Nickel Stainless Steel Clad Steel Plate", ASTMA265 "Specification for Nickel and Nickel Alloy Clad Steel Plate", ASTMB898 "Specification for Active and Corrosion-resistant Metal Clad Steel Plate" The provisions of the standard only stipulate that the chemical composition of the material should meet the requirements of the corresponding material standard.

Titanium alloys can still maintain their mechanical properties at low and ultra-low temperatures. Titanium alloys with good low-temperature performance and extremely low interstitial elements, such as TA7, can maintain certain plasticity at -235 degrees Celsius. Therefore, titanium alloys are an important low-temperature structural material.
