BT-3 (БТ-3)
BT-3 Titanium Alloy: Premium Quality for Aerospace & Marine Applications
BT-3 aluminum is a high-strength, heat-treatable alloy commonly used in industries requiring both strength and lightweight properties. This alloy is part of the 2xxx series of aluminum, known for its excellent mechanical properties, particularly in terms of tensile strength, fatigue resistance, and formability. BT-3 aluminum is designed to meet the demands of applications in industries like aerospace, automotive, defense, and heavy machinery, where components need to withstand significant stress while remaining lightweight and durable
Overview of Titanium BT-3
BT-3 titanium alloy, also known as Ti-3Al-2.5V, is a high-strength, heat-treated titanium alloy primarily used in aerospace, defense, and high-performance industrial applications. This alloy is part of the alpha-beta titanium alloys, meaning it contains both alpha and beta phases, which contribute to its balanced combination of strength, toughness, and corrosion resistance. The composition of BT-3 titanium alloy includes 3% aluminum and 2.5% vanadium, which give it excellent mechanical properties and make it suitable for a wide range of demanding environments.
BT3-1 is a Russian (CIS) α+β (alpha-beta) titanium alloy (sometimes designated in the West as Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si) developed for high‐temperature, high‐strength structural applications (especially fasteners and discs) in aerospace.
In aerospace literature it is described as a titanium alloy fastener material developed by Russia, with service capability to ~400-500 °C in some applications.
Characteristics of the material BT-3
| Grade : | BT-3 ( BT-3 ) ( 1520 ) |
| Classification : | Aluminium wrought alloys |
Chemical Composition & Microstructure of BT3-1 Titanium Alloy
The typical (nominal) chemical composition of BT3-1 titanium alloy is approximately:
| Element | Composition (%) |
|---|---|
| Aluminium (Al) | ~6% |
| Molybdenum (Mo) | ~2.5% |
| Chromium (Cr) | ~1.5% |
| Iron (Fe) | ~0.5% |
| Silicon (Si) | ~0.3% |
| Balance | Titanium (Ti) |
This corresponds to the designation Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si, as cited by ScienceDirect.
Key Physical & Mechanical Properties of BT3-1 Titanium Alloy
Indicative properties (actual values may vary depending on heat treatment, section size, and temperature):
| Property | Typical Value / Observation | Source |
|---|---|---|
| Tensile Strength (room temperature, heat treated) | > 980 MPa (reported) | Fastener World Inc. |
| Tensile Strength (at 400 °C) | Higher than ~720 MPa (in some reports) | Fastener World Inc. |
| Fatigue / Cyclic Properties | Demonstrates strong performance under static and cyclic loading (e.g., compressor-disk applications) | ResearchGate |
| Density | ≈ 4.5 g/cm³ (similar to other α + β titanium alloys) | — |
| Service Temperature Range | Operable up to ~400 – 500 °C in certain fastener and disc applications | Fastener World Inc. |
These characteristics indicate that BT3-1 provides exceptional strength, reliable fatigue resistance, and stability at elevated temperatures, making it suitable for demanding aerospace and compressor applications.
