FAQs
What are the contents of Ti6242 alloy?
Ti6242 contains 6% aluminum, 4% vanadium, 2% tin and 2% zirconium, balance titanium. This composition provides an excellent combination of strength, toughness and corrosion resistance.
What heat treatment is used for Ti6242?
A typical heat treatment is to solution treat at 955°C, followed by aging at 595°C to achieve optimum strength. This results in a microstructure containing alpha and beta phases.
What is the tensile strength of Ti6242?
Tensile strength of wrought Ti6242 is around 130,000 psi (900 MPa) in the annealed state. After heat treatment, it can reach around 160,000 psi (1100 MPa).
What is the density of Ti6242 titanium alloy?
The density of Ti6242 is 4.43 g/cc, which falls between steel and aluminum alloys. This provides an excellent strength-to-weight ratio.
What is the difference between Grade 5 and Grade 23 Ti6242 powder?
Grade 5 powder has lower interstitial element levels (especially oxygen and nitrogen) than Grade 23, making it preferred for critical applications, but it comes at a higher cost.
What standards does Ti6242 powder conform to?
Key titanium powder standards are ASTM B348, AMS 4999, ISO 5832-3, ASTM F3049, ASTM F3001. These cover chemistry, particle size distribution, morphology, flow characteristics etc.
