TA2(GR2) Titanium Alloy Wire

Industrial pure titanium is divided into three grades: TA1, TA2 and TA3 according to the impurity content. The gap impurity elements of these three kinds of industrial pure titanium are gradually increased, so the mechanical strength and hardness thereof 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 for high wear and strength requirements. TA1 can be used for better molding performance.


TA1, TA2, and TA3 in the national standard correspond to Gr0, Gr1, and Gr2 in this UNS.


TA1 and TA2 have very good low temperature toughness and high low temperature strength when iron quantity ω is 0.095%, oxygen content ω is 0.08%, hydrogen content ω is 0.009%, and nitrogen content ω is 0.0062%. Low temperature structural material below -253°C.
