- Product Description
AMS 4911 Titanium Coil
Baoji Jucheng Titanium Industry Co., Ltd.is based in China's Titanium Valley and offers high-quality AMS 4911 Titanium Coil made to meet airplane material standards.The Ti-6Al-4V (Grade 5) alloy used in our coils has strict mechanical requirements, including a minimum tensile strength of 130 ksi (896 MPa), a yield strength of 120 ksi (827 MPa), and an elongation of 10%.Each coil has a thickness between 0.3 and 12.0 mm, and a width between 950 and 1500 mm.These coils go through a thorough annealing and pickling process.With over 20 years of experience working with titanium and a yearly inventory of 3,000 tons, we ensure that our coils have 0% alpha case embrittlement.We do this by keeping strict control over the thickness and keeping hydrogen levels below 150 ppm, which is important for critical aerospace uses.

What is AMS 4911 Titanium Coil?
Aerospace-grade Ti-6Al-4V alloy in continuous rolled form is represented by Coil.
Important production issues are addressed in this specification. For automated stamping and roll-forming processes, the annealed state maximizes formability. Compared to discrete sheet processing, your production benefits from lower scrap rates.
The alloy's 90% titanium base is balanced with 6% aluminum and 4% vanadium. With a density of 4.43 g/cm³, this chemical offers a remarkable strength-to-weight ratio. Up to working temperatures of 350°C (660°F), structural integrity is guaranteed.
Material failure is avoided via strict interstitial controls. Iron is kept below 0.30%, hydrogen is kept below 150 parts per million, and oxygen is kept below 0.20%. These restrictions remove the brittle surface layers that are typical of commercial grades.

Key Advantages
Superior Strength-to-Weight Performance
Your aerospace components achieve 30% weight reduction versus steel. The 4.43 g/cm³ density maintains structural load capacity in fuselage skins and wing spars.
Exceptional Fatigue Resistance
High-cycle pressurization testing confirms reliable performance. The uniform alpha-beta microstructure withstands repetitive stress in cabin pressurization cycles.
Continuous Manufacturing Compatibility
Coil format enables automated feeding systems. You reduce material waste by 25% in high-speed stamping operations compared to sheet stock.
Corrosion Resistance
The material resists aviation hydraulic fluids and jet fuel exposure. Your components maintain integrity in harsh chemical environments without protective coatings.

Primary Applications
Aerospace Structural Components
Fuselage skins, spar webs, and rib chords require AMS 4911 Titanium Coil for load-bearing applications. The material resists aerodynamic flutter at altitude while handling cabin pressurization stress.
Jet Engine Cold Section Parts
Fan blades, casing shrouds, and intake cowlings benefit from high-velocity particulate erosion resistance. You achieve significant weight savings over steel alternatives in centrifugal stress environments.
Precision Fastener Production
B2B manufacturers feed our coils into automated headers for rivet and bolt production. Consistent gauge control ensures massive-scale output meeting vibrational resistance requirements.
Defense and Marine Applications
Naval structures and military equipment utilize the alloy's corrosion resistance. Your projects gain durability in saltwater and chemical exposure scenarios.

FAQ
Q: What distinguishes AMS 4911 from commercial ASTM B265 Grade 5?
A: AMS 4911 imposes stricter interstitial controls and tighter dimensional tolerances. You get guaranteed aerospace-grade metallurgy with eliminated alpha case and controlled hydrogen content.
Q: Can you provide custom widths outside the 950-1500mm range?
A: Yes, our cold rolling equipment accommodates special width requests. Contact our technical team with your specifications for feasibility assessment.
Q: What is your typical lead time for 5-ton orders?
A: Standard gauge coils ship within 3-5 business days from inventory. Custom thickness orders require 15-20 days for production scheduling.
Q: Do you offer material testing beyond standard certifications?
A: We provide additional ultrasonic testing, eddy current inspection, and mechanical property verification upon request. All testing follows aerospace quality protocols.
Q: How should we store coils to prevent surface contamination?
A: Store in climate-controlled environments below 60% humidity. Keep protective wrapping intact until processing to avoid surface oxidation.
