The composition of the titanium alloy TC4 material is Ti-6Al-4V, which belongs to the (α+β) type titanium alloy and has good comprehensive mechanical and mechanical properties. The specific strength is greater. The strength of TC4 sb=1.012GPa, the density g=4.4*103, the specific strength sb/g=23.5, and the specific strength sb/g of alloy steel is less than 18. Titanium alloy has low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 that of iron and 1/10 that of aluminum, and the thermal conductivity of TC4 is l=7.955W/m·K.
1) TC4 thermal expansion coefficient:
TC4 titanium alloy has a series of advantages such as excellent corrosion resistance, small density, high specific strength, better toughness and weldability, etc., and has been successfully applied in aerospace, petrochemical, shipbuilding, automotive, medicine and other sectors. .
2) Mechanical properties of TC4 titanium alloy:

3) Chemical composition of TC4 titanium alloy:
TC4 contains titanium (Ti) balance, iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.20, aluminum (Al) 5.5～ 6.8, Vanadium (V) 3.5～4.5
Because industrial pure titanium has better comprehensive properties and excellent corrosion resistance, it has become an indispensable structural material for many industrial parts. As a bio-implant material, it has been widely used clinically since the 1960s. Among all the commonly used implant metal materials, titanium has good biocompatibility, and because its density and elasticity are close to human bones, and it is non-magnetic, in the three major metal implant materials of stainless steel, cobalt-chromium-molybdenum alloy and titanium, titanium It is the most promising bioengineering material. The application of titanium has solved many major engineering and technical problems, promoted scientific and technological progress, and brought obvious economic benefits. The excellent performance and huge potential of titanium have shown a broader prospect of its application.
