AMS 4981 — Titanium Alloy Bars & Forgings for High-Performance Aerospace

AMS 4981 covers titanium alloy bars, wire, forgings, and forging stock supplied in solution and precipitation heat-treated conditions. Recognised for a high strength-to-weight ratio, excellent fatigue performance, and robust corrosion resistance, AMS 4981 is widely used in aerospace hot-section and structural components, motorsport, and demanding industrial applications.

What Is AMS 4981?

AMS 4981 typically refers to the Ti-6Al-2Sn-4Zr-6Mo titanium alloy (commonly called Ti 6-2-4-6). The specification defines chemistry, heat treatment, microstructure, and mechanical properties for bars, forgings, and forging stock used in safety-critical aerospace, industrial, and high-temperature hardware.

• Round and flat bars, wire

• Closed/open-die forgings

• Forging stock for further processing

Why Engineers Choose AMS 4981

High Strength at Elevated Temperatures

• Solution + age (STA) condition delivers high tensile and yield strength

• Performance remains stable up to ~530 °C (application-dependent)

Excellent Fatigue & Creep Resistance

• Balanced α/β microstructure supports cyclic-load endurance

• Ideal for disks, rings, and rotating hardware

Corrosion Resistance & Long Service Life

• Strong oxide film provides marine and industrial corrosion protection

Typical Applications

• Aerospace: compressor discs, fan components, rings, structural parts

• Motorsport & performance: high-load drivetrain components

• Industrial & marine: critical parts requiring strength + weight savings

Chemistry & Mechanical Properties (Guide)

Values vary by melt route, size, and condition — final acceptance per purchase order and AMS 4981 revision.

• UTS (STA): ~160–170 ksi (1100–1170 MPa)

• 0.2% YS: ~150–160 ksi (1035–1100 MPa)

• Elongation: ~6–10%

Heat Treatment & Microstructure

• Solution Treat + Age (STA): required to achieve specification strength and toughness

• Microstructure: homogeneous α/β; avoids continuous α at grain boundaries

Machining, Forging & Weldability

• Forging: controlled temperatures near β-transus; precise reductions recommended

• Machining: high strength requires rigid setups, sharp tooling, and generous cooling

• Welding: difficult; specialized procedures and high-purity shielding needed if attempted

• Quality: VAR melt routes and strict inspection improve cleanliness

Forms We Supply (Buyer’s Guide)

• AMS 4981 bars: round / flat, peeled or ground, STA or annealed + STA

• AMS 4981 forgings & rings: open/closed-die with optional machining
