What this wire is for
Aerospace cables need to be strong. Light. Reliable. Steel cables work but they're heavy. Stainless cables corrode over time.
High tensile titanium wire for aerospace cables solves both problems. Stronger than steel by weight. Won't corrode. Lasts the life of the aircraft.
Flight control cables. Actuator cables. Lanyards. Safety wires. Anywhere a steel cable is too heavy or stainless won't survive.
Why titanium beats steel in cables
Steel is strong. 7.8 g/cm³. Titanium Grade 5 is 4.4 g/cm³. Same strength at half the weight. For an aircraft, that's real savings.
Fatigue life is better too. Titanium doesn't have the same corrosion fatigue issues as steel. No rust pitting. No stress corrosion cracking.
High tensile titanium wire for aerospace cables gives you the strength you need without the weight penalty.

Grade 5 vs Grade 7 - which one for cables
Grade 5 is the standard. Ti-6Al-4V. Used for most aerospace cables. Good strength. Good fatigue. Widely available.
Grade 7 (Ti-6Al-2Sn-4Zr-2Mo) is a beta alloy. Higher tensile. Better fatigue resistance at elevated temperatures. Used for high-performance cables near engines or in hot areas. More expensive. Harder to draw into fine wire.
For high tensile titanium wire for aerospace cables, Grade 5 covers 90% of applications. Grade 7 is for hot zones or extreme fatigue life requirements.
Where these cables actually fly
Engineered into aircraft and spacecraft. High tensile titanium wire for aerospace cables ends up in:
- Flight control cables. Ailerons, elevators, rudder. Steel cables work but titanium saves weight. Every pound saved is fuel.
- Actuator cables. Flaps, landing gear doors. Need to cycle thousands of times without failing.
- Lanyards and release cables. Ejection seats, cargo doors, emergency systems. Reliability is everything. Titanium doesn't corrode and stick.
- Safety wire. Locking nuts and bolts on engines. Titanium is strong enough and won't rust like steel.
- Spacecraft mechanisms. Deployable booms, solar array latches. No corrosion in space. Lightweight.
One place you don't use it? Where the cable runs over sharp edges without a liner. Titanium wire has poor wear resistance against itself or steel. Use liners or pulleys.
How it's made
Making high-strength titanium wire isn't easy. The material work-hardens. It wants to crack.
Our high tensile titanium wire for aerospace cables starts as rod. We draw it down through carbide dies. Multiple passes. Intermediate annealing between passes to keep it ductile.
Final heat treatment develops the high tensile properties. Too much heat and you lose strength. Too little and you don't hit spec.
Surface finish matters for fatigue. Scratches become crack starters. We polish or clean the wire after final draw to remove surface defects.
Fatigue - the real concern for cables
Cables don't fail from one big pull. They fail from thousands of small bends. Over pulleys. Around corners. Vibration.
High tensile titanium wire for aerospace cables has good fatigue life. Not as good as some specialty steels, but better than stainless in corrosive environments.
The key is surface quality. A scratch that's 5% of wire depth cuts fatigue life in half. Our wire is drawn and finished to minimize surface defects.
For long-life cables, specify Grade 7. The beta microstructure handles cyclic loading better than Grade 5.
Testing and certification
Aerospace cables get tested. A lot.
Every spool of high tensile titanium wire for aerospace cables comes with:
Heat number traceability back to the original melt. Tensile test results. Yield and elongation. Surface inspection report. Spool weight and length.
Third-party testing available on request. Chemical analysis. Microstructure. Fatigue testing if your spec requires.
Keep the paperwork. Your customer will ask for it.
FAQ
Q: Grade 5 or Grade 7 for flight control cables?
A: Grade 5 for most. It's strong enough and proven. Grade 7 if the cable runs near an engine or exhaust (high heat) or if you need maximum fatigue life. Ask your engineering team.
Q: What's the tensile strength range?
A: Grade 5: 1100–1300 MPa. Grade 7: 1200–1400 MPa. Depends on diameter. Fine wire tends toward the higher end. We report actual numbers per spool.
Q: What certifications do you provide?
A: AMS 4957 or AMS 4958 cert. Mill test reports with heat number. EN 10204 3.1 standard. 3.2 available. Customer source inspection welcome.
Q: Lead time for aerospace wire?
A: Stock diameters (0.8mm, 1.0mm, 1.2mm, 1.6mm) ship in 10–14 days with full paperwork. Non-stock sizes take 4–6 weeks. Grade 7 takes longer.
The bottom line
Steel cables work. But they're heavy. Stainless cables work. But they corrode over time.
High tensile titanium wire for aerospace cables gives you the strength you need at half the weight. No corrosion. No rust. No stress cracking.
Grade 5 for most. Grade 7 for hot or high-fatigue.
Clean wire. Tight tolerance. Full traceability. That's what aerospace requires.
