The Main Titanium Alloy Titanium Material TC4

Ordinary people usually talk about titanium is that titanium is a single product, in fact, this perception is inaccurate. Titanium is divided into pure titanium and titanium alloy.
Titanium alloy TC4 is the main bear, at present 60% of the titanium is mainly TC4. TC4 main composition for the Ti-6Al-4V, belongs to the (α + β) type of titanium alloy, has a good comprehensive mechanical mechanical properties.
TC4 titanium alloy belongs to the national standard call, different countries different call.
TC4 titanium alloy is developed by the United States in 1954 successful α - β-type titanium alloy, containing 6% of the α-stabilizing element lv (aluminum) and 4% of the β-stabilizing element V (vanadium). TC4 titanium alloy nominal composition of the aluminum equivalent of 6.0, the vanadium equivalent of 4.0, the annealed state contains 10% - 15% β-phase.
The thermal conductivity of TC4 titanium alloy is 1/5 of that of iron and 1/10 of that of aluminum, and the thermal conductivity of TC4 l=7.955 W/m-K.
The strength sb of TC4 titanium alloy reaches 1.012 GPa, while its density g is 4.51 g/cm3, making the strength-to-density ratio sb/g 23.5. This value is much higher than the strength-to-density ratio of alloy steels, showing its excellent strength and lightweight characteristics.
Physical properties of TC4 titanium alloy:
The worldwide production of TC4 (Ti-6Al-4V) alloy semi-finished products accounts for more than half of the total production of all kinds of titanium alloy semi-finished products, and more than 80% in the aerospace industry.The main forms of semi-finished products of TC4 titanium alloys are rods, forgings, sheet, plate, profiles and wires.
TC4 titanium alloy is mainly characterized by excellent comprehensive performance and good process performance. TC4 titanium alloy has medium room temperature strength and high temperature strength, good creep resistance and thermal stability, high fatigue resistance and crack extension resistance in seawater, as well as satisfactory fracture toughness and resistance to hot salt stress corrosion, the sensitivity to hydrogen is also smaller than TC2, TC1 alloys, is suitable for the manufacture of- 196 ~ 450 ℃ wide temperature range of work in a variety of parts, especially using the principle of damage tolerance limit the design of parts.TC4 titanium alloy also has excellent process plasticity and superplasticity, suitable for molding with a variety of pressure machining methods, and a variety of ways to weld and machining.

Application Scenarios of TC4 Titanium Alloy
Aerospace: TC4 titanium alloy is widely used in the aerospace field for the manufacture of aircraft, missiles, rockets and other components. Its high strength and low density make aircraft lighter and improve fuel efficiency, while having good corrosion resistance and being able to adapt to harsh air environments.
Chemical industry: TC4 titanium alloy is widely used in the chemical industry in the reactor, heat exchanger, storage tanks and other equipment. Its corrosion resistance can adapt to the erosion of various acids, alkalis and other chemicals to ensure the safe operation of equipment.
Automobile manufacturing: TC4 titanium alloy is used in automobile manufacturing for engine parts, chassis components and so on. The high strength and low density of titanium alloy can reduce the quality of the body and improve the performance of the automobile, and at the same time, it has heat-resistant, wear-resistant and other characteristics, which can meet the requirements of the automobile in the use of complex working conditions.
Sporting goods: TC4 titanium alloy is widely used in the field of sporting goods, such as golf clubs, bicycle frames and so on. Its high strength and excellent elasticity can provide better hitting force and shock absorption effect, and at the same time, it has corrosion resistance, adapting to the use of outdoor environment.
In conclusion, TC4 titanium alloy has a wide range of potential applications in aerospace, medical devices, chemicals, automotive manufacturing, sporting goods and other fields due to its excellent performance.
