Gr9 Titanium Alloy Metal Pipe Tube for Aerospace

Gr9 Titanium Alloy Metal Pipe Tube for Aerospace

XI AN LINHUI IMPORT AND EXPORT Co., LTD. manufactures premium Gr9 Titanium Alloy Metal Pipe Tube for Aerospace compliant with ASTM B861 and ASTM B338 standards. Our Gr9 titanium tubes feature an outer diameter of 114.3mm and standard 3m lengths, engineered specifically for aerospace hydraulic systems and chemical processing applications.

This Ti-3Al-2.5V alloy delivers tensile strength exceeding 620 MPa while maintaining excellent cold formability—solving the strength-formability paradox that limits Grade 5 applications. Direct mill supply ensures cost efficiency with complete heat number traceability.

Key Features & Benefits

Superior Strength-to-Weight Ratio

Our Gr9 Titanium Alloy Metal Pipe Tube for Aerospace offers 50% higher strength than commercially pure titanium at only 4.48 g/cm³ density. This reduces aircraft structural weight significantly compared to steel alternatives.

CWSR Temper Optimization

Cold Worked Stress Relieved condition maximizes yield strength to 483 MPa minimum while maintaining 10-15% elongation for complex bending without fracture risk.

Exceptional Corrosion Immunity

Maintains passive oxide layer integrity in seawater, oxidizing acids, and temperatures up to 315°C. Outperforms 316 stainless steel in marine environments.

Product information

Manufacturing Process

Step 1: Preparing the Billet

To remove segregation, high-purity titanium sponge combined with aluminum-vanadium master alloys is vacuum arc remelted (VAR) three times.

Step 2: Extrusion with heat

Mandrel technology is used to extrude billets heated to 950°C into seamless pipe blanks, guaranteeing that there are no weak corrosion points or weld seams.

Cold Working in Step Three

Through controlled work hardening, the pilgering method increases yield strength while reducing wall thickness by 30 to 50%.

Step 4: Reducing Stress

The best CWSR characteristics are obtained by thermal treatment at 550–650°C for two to four hours, which recovers ductility without completely annealing.

Quality Inspection

100% NDT Testing

Every tube undergoes ultrasonic testing per ASTM E213 and eddy current inspection per ASTM E426 to detect internal defects and surface cracks.

Mechanical Verification

Tensile strength, yield strength, and elongation tested at room temperature. Hydrostatic pressure testing confirms leak-free integrity.

Documentation

EN 10204 3.1 certificates provided with full heat number traceability. Third-party inspection available through SGS, BV, TÜV upon request.

Applications

Aerospace Industry

Hydraulic tubing for landing gear systems, fuel lines, and APU components where high strength and low weight are critical.

Chemical Processing

FAQ

Q: Can you supply tubes in CWSR condition per AMS 4943?

A: Yes, our standard production follows AMS 4943 specifications for aerospace hydraulic applications with verified mechanical properties.

Q: What is your minimum order quantity?

A: We support trial orders starting from 100 kg for stock items. Custom production MOQ varies by specification.

Q: Do you provide material test certificates?

A: Every shipment includes EN 10204 3.1 certificates with complete chemical composition and mechanical test results traceable to heat numbers.

Q: Is welding possible with Gr9 tubes?
