Titanium alloy performance

Titanium is a new type of metal, with its properties being related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. Pure titanium iodide has an impurity content of no more than 0.1%, yet it has low strength and high plasticity. The properties of most industrial-grade titanium include: density ρ=4.5g/cm³, melting point 1725°C, thermal conductivity λ=15.24W/(m·K), tensile strength σb=539MPa, elongation δ=25%, reduction of area ψ=25%, Young's modulus E=1.078×10^5MPa, and hardness HB195.

High intensity

Titanium alloys typically have a density of around 4.51 g/cm³, which is only 60% of steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloys is significantly greater than that of other metal structural materials, allowing for the production of lightweight, high-strength, and rigid components. Titanium alloys are used in aircraft engine components, frames, skins, fasteners, and landing gears.
