Ti 6Al-2Sn-4Zr-2Mo Titanium Bar

Arch Metals supplies Ti 6Al-2Sn-4Zr-2Mo titanium bar from Dallas, Texas, for aerospace and defense customers across Texas and the surrounding states. Often called Ti 6-2-4-2 or Ti-6242, it is a near-alpha titanium alloy designed for strength, creep resistance and stability at temperatures up to about 1000°F. We supply bar to AMS 4975 and AMS 4976 with certified material and saw cutting to size. Request a quote and we’ll confirm sizes and availability.

Ti 6-2-4-2 Conditions and Specifications

  • Bar, solution treated and stabilized (AMS 4975): heat treated for a stable microstructure and creep resistance in high-temperature service.
  • Bar and forgings (AMS 4976): covers bar and forging stock for engine and airframe parts.
  • Silicon-bearing variant (Ti 6-2-4-2S): a small silicon addition improves creep resistance further; available on request.

Typical Properties of Ti 6Al-2Sn-4Zr-2Mo

  • Ultimate tensile strength: about 145 ksi (1000 MPa)
  • Yield strength: about 135 ksi (930 MPa)
  • Elongation: about 15%
  • Maximum service temperature: about 1000°F (540°C)
  • Density: 0.164 lb/in³ (4.54 g/cm³)
  • Chemistry: titanium with about 6% aluminum, 2% tin, 4% zirconium and 2% molybdenum

These are typical values for Ti 6-2-4-2 bar at room temperature. Guaranteed minimums vary by specification, condition and size, so check the governing spec or your mill cert for design values.

Why Engineers Choose Ti 6-2-4-2 Titanium

Ti 6-2-4-2 keeps its strength and creep resistance well above the roughly 750°F limit of Ti 6Al-4V titanium, which is why it is widely used in the hot sections of jet engine compressors and in high-temperature airframe structure. It also offers good weldability and stability during long exposure to heat. Common uses for Ti 6-2-4-2 include:

  • Jet engine compressor disks, blades and cases
  • High-temperature airframe structure
  • Exhaust and afterburner components
  • Missile and hypersonic structures

Ti 6Al-2Sn-4Zr-2Mo Titanium FAQs

How hot can Ti 6-2-4-2 run?

It is commonly used for long-term service up to about 1000°F (540°C), well above the practical limit of Ti 6Al-4V.

What is the difference between Ti 6-2-4-2 and Ti 6Al-4V?

Ti 6-2-4-2 is a near-alpha alloy built for high-temperature strength and creep resistance. Ti 6Al-4V is stronger at room temperature, more widely available and lower cost.

What does the S in Ti 6-2-4-2S mean?

The S means a small silicon addition, typically about 0.08%, which further improves creep resistance.
