Looking for a high-performance material that delivers exceptional strength at extreme temperatures? Our Grade 6 titanium bar, also widely known by its chemical designation Ti-5Al-2.5Sn titanium rod, is engineered for the most demanding aerospace, defense, and chemical applications. Fully compliant with stringent industry standards like AMS 4926 and MIL-T-9047, we supply premium-quality round bars designed to guarantee reliability in your critical projects.
Grade 6 titanium (Ti-5Al-2.5Sn) is a highly specialized, all-alpha titanium alloy. Unlike the more ubiquitous Grade 5 (an alpha-beta alloy), Grade 6 cannot be strengthened through traditional heat treatment processes. It is strictly a non-heat treatable material, exclusively supplied and utilized in its annealed condition to relieve internal stresses while maximizing ductility.
While it cannot be heat-treated, this unique alpha microstructure yields specialized extreme-environment capabilities. Elite engineers and procurement specialists specify Grade 6 titanium for several distinct advantages:
Superior Weldability: Thanks to its all-alpha composition, it boasts exceptional weldability compared to alpha-beta or beta alloys. Welded joints retain near-base-metal strength and ductility, making it the premier choice for complex fabricated assemblies.
High-Temperature Stability: It maintains remarkable tensile strength, creep resistance, and structural integrity at elevated temperatures (up to 480°C / 900°F).
Outstanding Oxidation Resistance: It performs flawlessly in highly corrosive and oxidative environments, ensuring a prolonged service life for chemical processing equipment and jet engine parts.
Cryogenic Toughness: It resists embrittlement and retains significant structural toughness even at ultra-low cryogenic temperatures.
When sourcing Ti-5Al-2.5Sn titanium rods for advanced industrial applications, precision and compliance are non-negotiable. As a trusted Grade 6 titanium bar supplier, we maintain a robust inventory and offer custom manufacturing capabilities to meet the exact dimensions and exacting tolerances required by your engineering team.
Our materials are certified to global standards, ensuring flawless traceability and superior metallurgical integrity. We provide comprehensive EN 10204 3.1 Material Test Certificates (MTCs) with every shipment, alongside optional 100% Ultrasonic Testing (UT).

The exceptional performance profile of our Grade 6 titanium bar is rooted in its precise alloying. As an alpha titanium alloy, it utilizes Aluminum (Al) and Tin (Sn) as potent alpha stabilizers. Aluminum significantly elevates tensile strength and high-temperature stability, while Tin enhances solid-solution strengthening without compromising the material’s signature weldability.
To meet the unforgiving criteria of AMS 4926 and MIL-T-9047, we strictly control interstitial elements (such as Iron, Oxygen, and Carbon) to ensure optimal toughness.| Element | Symbol | Composition (%) |
|---|---|---|
| Aluminum | Al | 4.5 – 5.5 |
| Tin | Sn | 2.0 – 3.0 |
| Iron | Fe | ≤ 0.25 |
| Oxygen | O | ≤ 0.12 |
| Carbon | C | ≤ 0.08 |
| Nitrogen | N | ≤ 0.05 |
| Hydrogen | H | ≤ 0.015 |
| Titanium | Ti | Balance |
When evaluating materials for load-bearing structural components, engineers prioritize a superior strength-to-weight ratio coupled with reliable stress performance. The Ti-5Al-2.5Sn titanium rod delivers formidable strength—even at elevated temperatures up to 480°C (900°F)—while simultaneously holding its ground in cryogenic environments.

Because of its distinctive all-alpha titanium microstructure, Grade 6 offers a rare combination of high-temperature stability, flawless weldability, and cryogenic toughness. This establishes the Ti-5Al-2.5Sn titanium rod as the definitive choice for applications where standard Grade 5 titanium might falter, or where intricate welding is mandatory.
Typical applications for our premium Grade 6 titanium bars include:
For engineers and procurement managers, deciding between a Grade 6 titanium bar (Ti-5Al-2.5Sn) and the more ubiquitous Grade 5 (Ti-6Al-4V) is a frequent dilemma.
Microstructure & Heat Treatment: Grade 5 is an alpha-beta alloy capable of being strengthened via heat treatment. Grade 6 is an all-alpha titanium alloy and is strictly non-heat treatable.
Weldability: The Grade 6 titanium round bar offers vastly superior weldability, achieving near 100% joint efficiency without the need for post-weld heat treatment. Grade 5 offers only fair weldability and typically requires post-weld annealing.
Extreme Temperature Performance: Grade 6 is explicitly engineered for extremes. It maintains superior creep resistance and tensile strength at elevated temperatures (up to 480°C / 900°F).
The Verdict: Specify Grade 5 for general-purpose, high-strength machined parts (click here to explore our Grade 5 Titanium inventory). However, you must specify Ti-5Al-2.5Sn when your assembly demands complex welding, sustained high-temperature stability, or when strictly mandated by AMS 4926 or MIL-T-9047 aerospace and military specs.
No. Grade 6 is an all-alpha titanium alloy, meaning it cannot be strengthened through traditional heat treatments like solution treating and aging. It is exclusively supplied and utilized in the annealed condition to relieve stresses while securing its excellent weldability and toughness.
The defining difference lies in weldability and extreme-temperature performance. While Grade 5 is heat-treatable for higher room-temperature strength, Grade 6 is specified for its superior weldability (requiring no post-weld heat treatment) and its remarkable ability to maintain high strength (~825 MPa yield strength) at elevated temperatures up to 480°C (900°F).
