Effect of chemical composition on performance
Aluminum (Al): Enhances the strength and heat resistance of the
alloy, and improves room temperature strength and hot strength
performance by solid solution strengthening of the α phase.
Vanadium (V): Not only improves the strength of the alloy, but
also improves its plasticity and machinability.
Other elements: The presence of impurity elements such as oxygen,
iron, carbon, hydrogen and nitrogen has a certain effect on the
performance of the alloy, but it needs to be controlled within a
specific range to maintain its excellent physical and chemical
properties.

Application fields
TC4 titanium alloy is widely used in aerospace, biomedicine,
chemical industry, automobile and other fields due to its high
strength, low density, good corrosion resistance and high
temperature resistance. In aerospace, TC4 titanium alloy is used to
manufacture aircraft structural parts, aero-engine parts, etc.; in
biomedicine, it is used to manufacture artificial joints, dental
implants and cardiovascular stents, etc.; in the chemical industry,
it is used to manufacture corrosion-resistant pumps and equipment.
The main chemical component of TC4 titanium alloy is titanium (Ti),
with 6% aluminum (Al) and 4% vanadium (V) added. The composition of
this alloy gives it unique physical and chemical properties. First,
its density is about 4.5g/cm³, which is much lower than many other
high-strength metals such as steel and nickel alloys, making TC4
titanium alloy an ideal choice for reducing weight while
maintaining structural strength. Secondly, TC4 titanium alloy has
extremely high tensile strength, which can reach more than 900MPa,
and has good toughness and can withstand large mechanical stress.
In addition, it exhibits excellent corrosion resistance in a
variety of corrosive media, especially in seawater, chlorides and
certain acidic environments. This property makes TC4 titanium alloy
the preferred material in marine engineering and chemical
equipment. Finally, TC4 titanium alloy can still maintain high
strength and good mechanical properties at high temperatures,
making it have a wide range of application potential in
high-temperature environments.
In the field of aerospace, the application of TC4 titanium alloy is
almost everywhere. From aircraft engine blades, turbine discs to
fuselage structural parts, TC4 titanium alloy has become a key
material for improving aircraft performance and extending service
life due to its light weight, high strength, high temperature
resistance and corrosion resistance. Especially in the new
generation of high-speed aircraft, manned spacecraft and deep space
probes, the application of TC4 titanium alloy is indispensable. For
example, in the manufacture of rocket engines, TC4 titanium alloy
is used to manufacture combustion chambers and nozzles, which can
maintain structural integrity and stability under extreme
conditions of high temperature and high pressure. In aircraft
manufacturing, TC4 titanium alloy is used to manufacture key
components such as landing gear, wing beams and skins, which
significantly improves the aircraft's load-bearing capacity and
flight safety.
