Explain |
TA7 titanium alloy is a medium strength α Type single-phase titanium alloy, containing 5% α Stable element aluminum and 2.5% neutral element tin. The alloy can not be strengthened by heat treatment. Its density is 4.42g/cm3, room temperature elastic modulus is 113GPa, Poisson's ratio is 0.33, and hardness is 277-286HB. It is characterized by good thermal strength and good fusion welding performance. Its process plasticity is low, and the plate forming should be carried out in the heating state. |
