Ti-6Al-4V Titanium Tube

Features 

Primary Use: Ti-6Al-4V is extensively used in the aerospace industry due to its high strength-to-weight ratio. Although it's not as malleable as other alloys, it is still used in tubular forms where strength is crucial.

Applications: Frequently used in aerospace, military, medical, and high-performance applications like turbine blades, engine components, and structural parts of aircraft.

Material Composition:

Titanium (Ti): 90-94%

Aluminum (Al): 5.5-6.75%

Vanadium (V): 3.5-4.5%

Iron (Fe): ≤0.25%

Carbon (C): ≤0.08%

Oxygen (O): ≤0.20%

Nitrogen (N): ≤0.05%

Hydrogen (H): ≤0.0125%

Mechanical Properties:

High Strength: This alloy is renowned for its high tensile strength and fatigue resistance, making it ideal for parts that experience high stress.

Heat Treatable: Ti-6Al-4V can be heat treated to further enhance its strength.

Good Weldability and Fabricability: Although it's not as malleable as other materials, it has good properties for welding and can be easily formed into complex shapes.

Ductility: Despite its high strength, it still retains a reasonable level of ductility (ability to deform without breaking), which is important for certain applications.

Manufacturing Process:

Extrusion: The material is extruded into tube form, allowing it to be shaped into thin-walled tubes for use in various applications.

Drilling: Additional processing like drilling can be done to create holes or specific shapes.

Standards:

ASTM B338: Standard specification for titanium and titanium alloy seamless pipe and tube, often used for aerospace and other demanding environments.

ASTM B861: Standard specification for titanium and titanium alloy welded tube.

Dimensional Range:

Outer Diameter: 1 mm to 100 mm

Wall Thickness: 0.1 mm to 12 mm

Length: Up to 6000 mm

Summary:

Ti-6Al-4V (Grade 5) titanium tube is highly valued for its combination of strength, toughness, and relatively low weight. It is widely used in critical applications such as aerospace structures where high performance is needed. The tube can be fabricated and welded easily, though its mechanical properties are more commonly utilized in sheet and plate forms due to its less malleable nature.
