TA15 Titanium alloy

TA15 titanium alloy (national standard grade, nominal composition Ti-6.5Al-2Zr-1Mo-1V) is a near-alpha type high-temperature titanium alloy independently developed in China, corresponding to the Russian grade BT20. It is specifically designed for long-term high-temperature service environments below 500℃ and is a key structural material in the aerospace field.

I. Core Performance Characteristics

Alloy Type: Near-α type titanium alloy

Density: 4.45 ~ 4.5 g/cm³ (significantly lightweight advantage)

Long-term operating temperature: 500℃ (up to 550℃)

Instantaneous temperature resistance: Up to 650℃~800℃

Typical mechanical properties:

Room temperature tensile strength: 900 ~ 1100 MPa

500℃ high-temperature strength: ≥ 620 MPa (far superior to TC4)

Main advantages:
Excellent heat resistance and creep resistance: High strength retention at high temperatures, stable long-term service.

Good weldability: Low weld crack sensitivity; joint strength can reach over 85% of the base metal.

Excellent corrosion resistance: Resistant to corrosion from seawater, chloride ions, H₂S/CO₂, and other media.

High specific strength: Low density, high strength, significant weight reduction (approximately 40% lighter than steel). II. Main Applications

1. Aerospace (Core Application)

Aero-engines: High-pressure compressor blades, discs, drums, intermediate casings, and other high-temperature components (operating temperature 450-500℃).

Aircraft structural components: Wing spars, load-bearing frames, fuselage panels, tail fins, high-temperature ducts, thermal insulation supports, etc.

Aerospace equipment: Rocket fuel tanks, engine nozzle expansion sections, satellite propulsion system piping, etc.

2. Shipbuilding and Marine Engineering

Deep-sea equipment: Submarine pressure hulls, deep-sea submersible manned cabins, deep-sea probe frames, etc.

Offshore platforms: Seawater pipelines, valves, pump bodies, heat exchangers, and other corrosion-resistant structural components.

3. Energy and Chemical Industry

Nuclear power: Steam generator components, spent fuel processing equipment.

Oil and gas: Sulfur-resistant downhole tools, high-pressure valves, geothermal well casings, heat exchangers.

New energy: High-pressure hydrogen storage and transportation tanks, LNG cryogenic valves.

4. Other High-End Manufacturing

Automotive: High-temperature components for racing engine, lightweight connecting rods.

Weaponry: Artillery barrel liners, lightweight structures for armored vehicles.

Quality Control and Testing

Each product undergoes rigorous inspection before shipment:

Dimensional Inspection: Precise measurement of thickness, length, and width

Chemical Composition and Mechanical Property Analysis: Third-party testing reports

Surface Inspection: Visual and microscopic inspection for defects

Ultrasonic Testing: Detection of internal defects
