Titanium alloy is a metallic material composed of titanium and other metals. It is a crucial structural metal known for its high strength, corrosion resistance, and ability to withstand high temperatures. Titanium alloys are primarily utilized in the aerospace industry for aero-engine components and structural elements of aircraft.
Titanium's properties are influenced by the presence of carbon, nitrogen, hydrogen, and oxygen. The impurity content in titanium alloys should not exceed 0.1%. While titanium possesses low strength and high plasticity, the addition of other metals enhances its performance. Industrial pure titanium alloy, with a purity of 99.5%, exhibits the following characteristics: density (ρ) of 4.5g/cm³, melting point of 1725 degree , thermal conductivity (λ) of 15.24W/(m·K), tensile strength (σb) of 539MPa, elongation (δ) of 25%, section shrinkage (ψ) of 25%, elastic modulus (E) of 1.078×10^5MPa, and hardness (HB) of 195.


Titanium alloys find extensive use in the manufacturing of compressor parts for engines. They are employed in various industries for producing electrodes in the electrolytic industry, power station condensers, oil refining and desalination heaters, and environmental pollution control devices. Titanium and its alloys have become crucial materials for corrosion-resistant structures. Additionally, they are used in the production of hydrogen storage materials and shape memory alloys.
