AMS 4928 Ti-6Al-4V Titanium Wire Description
AMS 4928 Ti-6Al-4V Titanium Wire Introduction
AMS 4928 Ti-6Al-4V titanium wire is premium aerospace-grade alpha-beta titanium alloy material with exceptional comprehensive mechanical performance. It delivers far higher tensile and yield strength than commercially pure titanium grades while retaining reliable ductility and excellent processability. Rigorous aerospace impurity control limits hydrogen content within 0.0125% and oxygen content below 0.20%, securing ultra-stable internal quality and consistent batch-to-batch performance.
Boasting an outstanding strength-to-weight ratio, superior fatigue resistance and remarkable universal corrosion resistance, it performs steadily in harsh marine, chemical and high-temperature working conditions. Widely adopted for high-strength fasteners, aircraft structural components, precision fabrication and aerospace welding structures, it serves high-end aerospace scenarios demanding extreme reliability, structural stability and durability.

Core Advantages
- Strong and tough: The Ti-6Al-4V dual-phase composition gives stable mechanical properties. It is a reliable choice for aviation load-bearing parts. You get the right balance of strength, ductility, and crack resistance.
- Light weight: Density is only 56% of steel. With the same strength, you can reduce weight by more than 40%, which improves equipment performance. This is a big advantage in aerospace, where every gram matters.
- Corrosion and temperature resistant: It can stands up to harsh chemicals and works from -253°C up to 400°C—perfect for extreme conditions. It can also resists seawater, acids, and chlorides, so it lasts longer in tough environments.
- Easy to work with: Precision drawn, tight tolerances. Works well with welding, 3D printing, and other processes. You can bend it, form it, or weld it without cracking or losing strength.
Typical Applications
- Fasteners & Springs: Bolts, nuts, lockwire, springs. 40-50% lighter than steel, no galvanic corrosion.
- Engine Components: Lockwire for nuts, binding rings/woven rings for compressor blades, disks, casings. Reduces rotor weight.
- Composite Joints (CFRP): Woven mesh or pins prevent galvanic corrosion with carbon fiber.
- Airframe & Cockpit: Seat frames, hydraulic lines, conduit clamps, thermal insulation mesh. Better creep resistance than aluminum.
- Landing Gear & Brakes: Brake disc return springs, hydraulic seal support rings, tube fittings.
Precautions
Titanium fire risk (ignites in pure oxygen or under dry friction at high temperatures)–avoid oxygen-rich environments or severe friction.
Notch sensitivity–Do not reverse-bend after forming.
