Titanium alloy TC4 is a typical (α+β)-type titanium alloy, and the corresponding grade of TC4 is Ti-6Al-4V. Because it contains 6% α-stabilizing element Al and 4% β-stabilizing element V, TC4 has good comprehensive performance. And it has the advantages of low density, high specific strength, good corrosion resistance and good process performance, which makes it a more ideal structural material for aerospace engineering with high specific strength.

Titanium alloy TC4 can be used for a long time in the 400 ℃ environment, the aviation industry is mainly used in the manufacture of engine fan and compressor disk and a few pieces, as well as the aircraft structure of the beams, joints and spacer frames, and other important establishment of the structural parts. TC4 is mainly used in the annealed state, but also can be used in solid solution failure treatment to further clear the, has a good process plasticity and superplasticity for a variety of pressure machining molding. Can also be used in a variety of ways for welding and machining.

TC4 titanium alloy density: 4.5 (g/cm3) working temperature -100 ~ 550 (℃)

The strength of TC4 is sb=1.012GPa, specific strength sb/g=23.5, while the specific strength of alloy steel sb/g is less than 18.
