Description
🔹 Overview
The Ti-7Al-4Mo alloy, compliant with AMS 4970, is a high-performance titanium alloy specifically engineered for elevated-temperature aerospace applications. Known for its superior strength, excellent creep resistance, and remarkable thermal stability, this α-β alloy outperforms standard grades such as Ti-6Al-4V in heat-intensive environments.
At Shaanxi Nickel Titanium Copper Metal Co., Ltd., we manufacture precision-machined Ti-7Al-4Mo alloy bars, rings, discs, and forged components for industries demanding the highest mechanical integrity. Our materials are fully certified to AMS 4970 standards, and we provide full customization, tight tolerances, and worldwide delivery.
🔹 Chemical Composition (Typical)
| Element | Content (wt.%) |
|---|---|
| Aluminum (Al) | 6.5 – 7.5 |
| Molybdenum (Mo) | 3.5 – 4.5 |
| Iron (Fe) | ≤ 0.5 |
| Oxygen (O) | ≤ 0.15 |
| Carbon (C) | ≤ 0.08 |
| Nitrogen (N) | ≤ 0.05 |
| Hydrogen (H) | ≤ 0.015 |
| Titanium (Ti) | Balance |
This carefully balanced composition provides a stable α+β phase structure that contributes to the alloy’s mechanical and thermal superiority.
