6al4v titanium sheet

6Al4V Titanium Sheet - High-Performance Grade 5 Alloy

LINHUI TITANIUM offers Grade 5 (Gr5) material with an outstanding strength-to-weight ratio and produces precise 6al4v titanium sheet that complies with ASTM B265. Our sheets are ≥0.5 mm thick, 1000–2000 mm wide, and up to 6000 mm long thanks to carefully regulated cold and hot rolling processes. This titanium sheet retains mechanical integrity up to 400°C with a minimum tensile strength of 895 MPa and a yield strength of 828 MPa. Pickling and polished surface finishes are available, and for consistent forming performance, the thickness tolerance is controlled within ±0.05mm. With a density of 4.43 g/cm³, it is 45% lighter than steel and offers better corrosion resistance thanks to spontaneous TiO2 passive film generation.

Important Features & Advantages

Unlike commercially pure grades, our titanium sheet offers heat-treatable capabilities. The substance is resistant to air corrosion, chlorides, and seawater without deteriorating..
Superplastic formability at elevated temperatures enables complex geometries. You gain reduced assembly costs through fewer welded joints.
Low modulus of elasticity matches human bone properties. This makes it ideal for biomedical applications requiring stress shielding reduction.

Manufacturing Process

We utilize vacuum arc remelting (VAR) to produce homogeneous ingots. Multiple remelts eliminate segregation and ensure chemical uniformity.

Hot rolling reduces ingot thickness at controlled temperatures below beta transus (980-995°C). This creates equiaxed alpha-beta microstructure.

Cold rolling achieves final gauge with ±0.05mm precision. Intermediate annealing cycles prevent work hardening and cracking during reduction passes.

Solution treatment and aging (STA) can be applied upon request. Final pickling removes oxide scale, while polishing achieves mirror finishes for critical applications.

Internal discontinuities more than 1 mm are detected by 100% ultrasonic testing. Surface-breaking flaws are detected by eddy current inspection down to a depth of 0.1 mm.

According to ASTM E8, tensile testing confirms mechanical properties. Uniform heat treatment across sheet dimensions is ensured via hardness mapping.

Optical emission spectrometry chemical analysis verifies conformance with composition. Grain size and phase distribution that satisfy AMS 4911 standards are shown by metallographic analysis.

Complete traceability is offered by EN 10204 3.1/3.2 material test certificates. SGS, BV, TÜV, and DNV offer third-party inspection services.

6al4v Titanium Sheet Applications

Aerospace Structural Components: Our 6al4v titanium sheet is used in landing gear supports, bulkheads, and fuselage skins. High cyclic loads and temperature changes from -55°C to 400°C are tolerated by the material without causing fatigue failure.

Biomedical Implants: Orthopedic instruments and craniofacial plates are served by the ELI version. Stress shielding in patient-matched devices is decreased by modulus compatibility with bone.

Marine and Offshore Equipment: Heat exchangers and subsea housings are resistant to saltwater and H2S crevice corrosion. In these conditions, the service life is three to five times longer than that of stainless steel.

Defense Armor Systems: Compared to steel armor, ballistic protection panels save weight by 45% while deflecting missiles.

Export Markets

We have shipped hundreds of thousands of tons to more than 60 nations. North America, Europe, the Middle East, and Southeast Asia are the main markets.

CEFC, PTT, PDVSA, PETRONAS, and LUKOIL are longstanding partners. Our product supports vital infrastructure in the aerospace, chemical processing, and oil and gas industries.

FAQ

Q: Can you supply extra-thin gauges below 0.5mm?

A: Yes, we produce foils down to 0.1mm through specialized cold rolling. Lead time extends to 30-35 days for non-stock thicknesses.

Q: What's the difference between annealed and STA condition?

A: Annealed offers better formability for complex shapes. STA increases strength by 15-20% but reduces ductility, suitable for structural applications.

Q: Do you provide cut-to-size services?

A: Absolutely. Laser cutting, waterjet, and shearing available. Supply CAD drawings for custom blanks with ±0.5mm dimensional tolerance.

Q: How does Grade 5 compare to Grade 2 for corrosion resistance?

A: Both form protective oxide layers. Grade 5 offers 2x tensile strength, making it preferable when mechanical loads combine with corrosive exposure.

Q: What certificates accompany shipments?

A: EN 10204 3.1 MTC, material composition report, mechanical test results, and heat treatment records. Third-party inspection arranged upon request.
