Titanium and its alloys have emerged as indispensable materials across a wide range of high-performance industries. Among the most reliable and sought-after grades are Ta6V, Ta11, Ta18, and Ta19. These titanium alloy tubes and pipes are known for their exceptional strength-to-weight ratio, resistance to extreme corrosion, and excellent stability under elevated temperatures.Whether used in critical aerospace assemblies, offshore environments, medical implants, or high-pressure chemical systems, these grades are specifically engineered to meet the most demanding operational challenges. Each alloy has a distinct chemical composition and performance profile, offering engineers and manufacturers the flexibility to choose the most appropriate material for their project.
Titanium alloys are broadly classified into alpha, beta, and alpha-beta phases. The Ta6V (Ti-6Al-4V), Ta11 (Ti-5Al-2.5Sn), Ta18 (Ti-3Al-2.5V), and Ta19 (Ti-6Al-2Sn-4Zr-2Mo) all belong to different categories and exhibit unique mechanical, thermal, and structural properties. They are commonly manufactured into seamless and welded tubes and pipes in accordance with global standards like ASTM B338, ASTM B861, and ISO 5832.
Ta6V is the most commonly used titanium alloy worldwide. As an alpha-beta alloy, it offers a superior combination of strength, fatigue resistance, and moderate corrosion resistance. It is extensively used in:
Aerospace engine components and airframe structures
Hydraulic systems and landing gear tubing
Medical implants such as bone screws and prosthetics
High-performance automotive and motorsport parts
Known for its excellent creep resistance at elevated temperatures, Ta11 is ideal for service in hot gas environments. It is often chosen for:
Compressor casings in jet engines
High-temperature heat exchanger tubing
Space propulsion systems
Ta18 combines good mechanical strength with superior weldability and cold formability. Its excellent resistance to seawater corrosion makes it a preferred material in:
Marine and offshore piping systems
Chemical transport and processing equipment
Hydraulic and instrumentation tubing
Ta19 is a high-performance titanium alloy designed for structural applications under elevated temperatures. Its excellent creep resistance and thermal stability make it suitable for:
Jet engine compressor components
Advanced gas turbine hardware
High-load aerospace fasteners and structural tubing
| Grade | Composition | Density (g/cm³) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Max Operating Temp (°C) |
|---|---|---|---|---|---|---|
| Ta6V | Ti-6Al-4V | 4.43 | 900 – 1100 | 830 | 10 – 15 | 400 |
| Ta11 | Ti-5Al-2.5Sn | 4.48 | 860 – 960 | 800 | 10 – 14 | 500 |
| Ta18 | Ti-3Al-2.5V | 4.48 | 700 – 860 | 620 | 12 – 18 | 400 |
| Ta19 | Ti-6Al-2Sn-4Zr-2Mo | 4.55 | 950 – 1100 | 900 | 8 – 12 | 600 |
High resistance to chloride-induced corrosion and crevice corrosion
Excellent mechanical strength with reduced weight
Outstanding biocompatibility for surgical and biomedical use
Extended service life in aggressive chemical environments
Resistant to thermal fatigue and creep at high temperatures
All titanium alloy tubes and pipes supplied are manufactured under ISO-certified quality systems and conform to international standards including:
ASTM B338/B861 – Seamless and welded titanium tubes
AMS 4943, 4944 – Aerospace titanium tubing standards
ISO 5832 – Implants for surgery
NACE MR0175 – Compliance for sour gas environments
Ta6V is a general-purpose titanium alloy offering an excellent balance of strength and corrosion resistance. Ta19, on the other hand, is designed for high-temperature aerospace applications and provides better creep resistance and thermal stability.
Yes. Ta6V and Ta18, in particular, are biocompatible and widely used in medical implants, surgical tubing, and orthopedic applications. They comply with ISO 5832 and ASTM F136 standards.
Absolutely. We provide custom OD, wall thickness, and lengths according to customer drawings or specifications. Precision cutting, polishing, and CNC machining services are also available on request.
Standard products are available from stock and can be shipped within 7–10 days. Customized orders may take 3–6 weeks depending on specifications and production capacity.
Titanium alloys require specialized tooling for machining and an inert gas (argon) environment for welding. Grades like Ta6V and Ta18 have relatively good weldability when proper procedures are followed.
