Aerospace Grade 6al-4v Titanium Bar
Aerospace grade 6Al-4V titanium rod, also known as Ti-6Al-4V or grade 5 titanium, is an alpha-beta titanium alloy named after its composition contains 6% aluminum and 4% vanadium. This titanium alloy is known for its high strength-to-weight ratio, excellent corrosion resistance and excellent high temperature resistance. It also has good processing performance and fatigue resistance. It is one of the most widely used titanium alloys at present.
Thanks to its light weight and reliability, 6Al-4V titanium rods are widely used in aircraft structural parts, engine core components and aviation fasteners, such as wing reinforcements, turbine blades and landing gear frames. They perform well in extreme environments and help improve aircraft performance and durability.

Chalco 6al-4v titanium bar featured products
6Al-4V hot-rolled titanium bar is formed by rolling titanium alloy at high temperatures. It has a rough surface but a uniform internal structure. It offers good plasticity and low internal stress, making it suitable as a billet material for large aerospace structural components or parts that require further processing, such as wing reinforcements and support structures.
6Al-4V cold-drawn titanium bar is manufactured using a drawing process at room temperature. It has a smooth surface, high dimensional accuracy, and higher strength, but may retain internal stress. It is widely used in aerospace fasteners, high-precision shaft components, and small standard parts that do not require secondary processing, making it particularly suitable for applications with strict precision requirements.
6Al-4V forged titanium bar is formed through high-temperature forging. Its internal structure is dense and defect-free, offering exceptionally high strength and toughness, making it capable of meeting the demands of high-load and high-temperature environments in aerospace. It is typically used to manufacture landing gear, turbine components, and other critical load-bearing parts, demonstrating excellent reliability and durability.
The characteristics of aerospace-grade 6al-4v titanium bar
High strength
The tensile strength of 6al-4v titanium alloy reaches up to 830 MPa, with a yield strength close to 795 MPa, demonstrating exceptionally high strength characteristics. This makes 6al-4v titanium bar particularly suitable for structural components in aerospace that need to withstand heavy loads, such as aircraft frames and landing gear, significantly improving the overall stability and safety of the structure.
High temperature stability
6Al-4V titanium alloy maintains excellent mechanical properties at temperatures above 400°C, exhibiting outstanding thermal stability. Titanium bars made from this alloy are particularly suitable for high-temperature components in aerospace engines, such as compressor discs and fasteners in the combustion chamber, where they can maintain reliability in high-temperature environments.
Lightweight design advantage
6al-4v titanium alloy has a density of only 4.43 g/cm³, about 40% lighter than steel, yet with comparable or even higher strength. As a result, 6al-4v titanium bar is the preferred choice for lightweight design, helping to reduce weight in aerospace vehicles, improve fuel efficiency, and lower overall energy consumption of the aircraft.
Excellent fatigue and crack resistance
Due to its high fatigue limit and excellent crack resistance, titanium bars made from 6Al-4V titanium alloy can maintain structural integrity under repeated loading and vibration. This characteristic makes it ideal for key components, such as aircraft landing gear and power system connections, which are subjected to dynamic loads over long periods.
Corrosion resistance
6Al-4V titanium alloy exhibits strong resistance to corrosion from common environmental factors in aviation, such as moisture, high-salinity gases, and aviation fuels. Titanium bars made from this alloy perform excellently in exposed aircraft parts, such as external fasteners and wing supports, significantly reducing maintenance and replacement costs caused by corrosion.
Excellent machinability
6Al-4V titanium alloy combines good machinability and weldability, making titanium bars produced from it more efficient in the manufacturing of complex aerospace structural components. This machining advantage not only reduces production difficulty but also improves product precision and consistency.
