Working with Ti-6Al-4V (AM, F2924)-AB

Is Ti-6Al-4V (AM, F2924) easy to machine?

Machine with rigid setups, sharp uncoated-carbide or AlTiN tools, low surface speed (30–50 m/min) and copious high-pressure coolant; never dwell — work hardening and chip fires are the main risks.

Can Ti-6Al-4V (AM, F2924) be welded?

Excellent by GTAW, laser and EB welding with full argon/vacuum shielding and back purge; keep O/N/H pick-up low, avoid oxide-contaminated (straw/blue) welds, no flux processes.

Can Ti-6Al-4V (AM, F2924) be formed, bent or molded?

Net shape comes from the build; supports and lattices must be designed for removal, and thin walls need stress relief on the plate before cutting off to prevent distortion.

What surface finishes work on Ti-6Al-4V (AM, F2924)?

Blast/tumble to remove partially sintered powder, then chemical milling, abrasive-flow or shot-peening for fatigue-critical surfaces; anodize (AMS2488) or passivate for medical use.

Ti-6Al-4V (AM, F2924)-AB — frequently asked

What is Ti-6Al-4V (AM, F2924)-AB used for?

Ti-6Al-4V (AM, F2924)-AB is typically used for aerospace brackets and housings, medical implants (non-ELI), complex lattice structures, prototype tooling and turbine and engine components. In short: highest-strength printed titanium; powder-bed fusion Ti-6Al-4V; aerospace and medical AM spec.

What is the yield strength of Ti-6Al-4V (AM, F2924)-AB?

Ti-6Al-4V (AM, F2924)-AB has a typical yield strength of 1,120 MPa (162 ksi) and a tensile strength of 1,250 MPa (181 ksi) — stronger than 99% of titanium grades. Strength varies by condition: see the 6 listed tempers.

Is Ti-6Al-4V (AM, F2924)-AB easy to machine?

Not especially — machinability is rated poor (15/100, worse than 97% of titanium grades). Machine with rigid setups, sharp uncoated-carbide or AlTiN tools, low surface speed (30–50 m/min) and copious high-pressure coolant; never dwell — work hardening and chip fires are the main risks.

Can Ti-6Al-4V (AM, F2924)-AB be welded?

Yes — weldability is rated good (65/100). Excellent by GTAW, laser and EB welding with full argon/vacuum shielding and back purge; keep O/N/H pick-up low, avoid oxide-contaminated (straw/blue) welds, no flux processes.

What surface finishes work on Ti-6Al-4V (AM, F2924)-AB?

Blast/tumble to remove partially sintered powder, then chemical milling, abrasive-flow or shot-peening for fatigue-critical surfaces; anodize (AMS2488) or passivate for medical use.

Can Ti-6Al-4V (AM, F2924)-AB be formed, bent or molded?

Net shape comes from the build; supports and lattices must be designed for removal, and thin walls need stress relief on the plate before cutting off to prevent distortion.

What is the maximum service temperature of Ti-6Al-4V (AM, F2924)-AB?

Ti-6Al-4V (AM, F2924)-AB is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between Ti-6Al-4V (AM, F2924)-SR and Ti-6Al-4V (AM, F2924)-HIP?

SR is the default condition — default commercial condition: removes build residual stress before plate removal while keeping high strength; use where static strength dominates. HIP: standard for flight- and implant-critical parts: closes gas porosity and lack-of-fusion, maximising ductility, toughness and fatigue life. Yield strength is 1,040 MPa in SR versus 880 MPa in HIP.
