Titanium in Aviation

Leading aircraft manufacturers choose titanium for one reason above all: its unmatched strength-to-weight ratio, outstanding corrosion resistance, and exceptional fatigue performance.

Leveraging these core advantages, aerospace-grade titanium alloys are integral to modern airframes—from load-bearing structures and high-pressure lines to critical fasteners. In hybrid structures with carbon-fiber-reinforced polymer (CFRP), titanium is the preferred interface material, enabling lighter, stronger aircraft designs.

As a dedicated aerospace titanium supplier, we deliver commercially pure titanium and aerospace-grade titanium alloys to international standards. Our portfolio covers titanium plate, titanium bar, titanium tube, and titanium forgings. Each shipment includes full MTR (Mill Test Report). Our quality system complies with AS/EN 9100, and special processes (heat treatment, welding, NDT) are performed by Nadcap-approved facilities.

Why Titanium in Aviation

Titanium is "irreplaceable” in modern aerospace not only because its density is ~60% of steel and its strength-to-weight ratio outperforms aluminum and most steels, but also because it maintains strength and dimensional stability in the mid-temperature range, offers High Fatigue Life, and has inherent Corrosion Resistance—all of which reduce inspection frequency and MRO costs. In composite airframes, titanium's compatibility with CFRP in electrochemistry and thermal expansion makes it the first choice for load-bearing joints, fasteners, and transition pieces.

Titanium Alloys

Aerospace Application Systems

Airframe & CFRP Interfaces

With higher composite content, joints and load paths face thermal-expansion mismatch and galvanic corrosion risks. Titanium has a closer CTE to CFRP, plus high corrosion resistance and crack tolerance—ideal for high-load areas near composites.

Landing Gear & High-Load Forgings

Landing imposes impact plus high-cycle loads—demanding high yield strength, fracture toughness, and reliable hardenability.

Recommended Alloys & Forms: Ti-10V-2Fe-3Al (10-2-3), Ti-5Al-5V-5Mo-3Cr (Ti-5553) for large closed-die/ring forgings; high-strength/elastic connectors: Beta-C.

Tubes & Ducts (Hydraulics / Fuel / Inerting / Bleed-Air)

Lightweight and corrosion-resistant systems need thin-wall capability, weldability, and clean inner surfaces.

Recommended Alloys & Forms: Ti-3Al-2.5V (Grade 9) CWSR/annealed seamless or welded tube; non-structural corrosion-resistant parts: CP Grade 2/3.

Standards: ASTM B338 (seamless), ASTM B861 (welded); AMS 4943/4944 (Gr9).

Fasteners & Joints

Mixed composite/metal airframes need weight reduction and galvanic protection.

Standards: NAS/AS/MS series; blanks to ASTM B348; finished parts to AMS mechanical classes with lot traceability.

QA & Selection: Hardness/tensile/torque, thread gauging, FPI sampling; CFRP interfaces with insulating collars & sealants; optional anodize or solid film lubricant (SFL).

Nacelle & Firewalls

Near hot/erosive zones, materials must resist heat, allow repair, and form complex shapes.

Recommended Alloys & Forms: Ti-6Al-4V thin sheet/profiles; local hot spots: Ti-6242; often combined with honeycomb sandwich (titanium face sheet), compatible with SPF/DB.

Standards: ASTM B265 (sheet/plate), AMS 4911 (Gr5 sheet/strip/plate).
