What Is Ti 6Al-4V (Grade 5)

What Is Ti 6Al-4V (Grade 5)

Ti 6Al-4V, also known as Grade 5 titanium, is a two-phase α+β titanium alloy, which combines the desirable properties of both phases.

The alloy exhibits high tensile strength, lightweight, and good fatigue resistance, which are essential for applications where failure is not an option. The addition of aluminum and vanadium enhances the alloy’s strength and thermal stability, making it suitable for high-performance components.

Titanium alloys are prized for their high strength-to-weight ratio, corrosion resistance, and ability to withstand extreme temperatures. These characteristics make them ideal for critical applications in aerospace, medical devices, automotive components, marine environments, and the energy sector. Ti 6Al-4V, in particular, is renowned for its excellent balance of strength, toughness, and workability, which is why it is the preferred choice in demanding engineering applications.

Ti 6al 4v Machinability

Material Properties

  • Hardness and Strength: Ti 6Al-4V has high hardness and tensile strength, making it resistant to deformation but challenging to cut.
  • Low Thermal Conductivity: Titanium alloys, including Ti 6Al-4V, have low thermal conductivity, causing heat to concentrate at the cutting zone, which can lead to tool wear and workpiece damage.
  • Elastic Modulus: The relatively low elastic modulus of Ti 6Al-4V can cause chatter and deflection during machining.

Work Hardening

Tendency to Work Harden: Ti 6Al-4V tends to work harden rapidly when subjected to cutting forces, making subsequent passes more difficult.

Physical Properties

Ti 6Al-4V exhibits unique physical properties that contribute to its widespread use:

  • Density: 4.43 g/cm³, which is about 60% of the density of steel, making it an ideal material where weight savings are crucial.
  • Melting Point: 1660-1670°C, which allows it to retain strength at high temperatures.

Chemical Reactivity

Reactivity with Tool Materials: Titanium has a high affinity for materials like iron, cobalt, and nickel, leading to tool adhesion and galling. This chemical reactivity necessitates the use of specialized tool materials and coatings.

Chemical Composition

The chemical composition of Ti 6Al-4V is a critical factor in its performance. The alloy consists of approximately:

  • Titanium (Ti): Balance
  • Aluminum (Al): 6%
  • Vanadium (V): 4%
  • Iron (Fe): ≤ 0.25%
  • Oxygen (O): ≤ 0.2%

This specific composition imparts the alloy with its distinctive properties, such as high strength, lightweight, and resistance to corrosion and high temperatures.

Mechanical Properties

The mechanical properties of Ti 6Al-4V are highly favorable for high-stress environments:

  • Tensile Strength: Typically ranges from 895 to 930 MPa.
  • Yield Strength: Approximately 880 MPa.
  • Elongation: About 10-15%, providing good ductility.
  • Hardness: Typically around 36 HRC.
