TA2
TA2/Gr1 is a kind of industrial titanium with a single α phase. The industrially pure titanium commonly used in industry is TA2 because of its corrosion resistance and comprehensive mechanical properties.Moderate. TA3 can be used when high wear resistance and strength requirements are required. TA1 can be used when better molding performance is required.
