|---|---|---|---|
| AMS 4911 | Ti-6Al-4V (Grade 5) | Structural airframe components, wings, fuselage chinametalsupply lastingtitanium | Up to 4.000" (101.6 mm) |
| AMS 4902 | Commercially Pure (CP-2) | Parts requiring corrosion resistance and formability universalmetals | Up to 4.000" (101.6 mm) |
| AMS 4928 | Ti-6Al-4V (Bar/Forgings) | Critical structural fasteners, engine discs alloymetalsco hst-titanium | N/A |
*Note: In industry terminology, material thickness exceeding 0.187 inches (4.76 mm) is typically classified as "plate," while thinner material is designated as "sheet."*
Pro Tip from Industry Experts: Always prioritize suppliers who provide full traceability, including mill test reports (MTRs) that map directly to the specific AMS lot number. This documentation is essential for AS9100-certified aerospace supply chains and is a core requirement for quality audits. [lastingtitanium](https://www.lastingtitanium.com/why-ams-4928-is-the-gold-standard-for-aerospace-titanium-bar-procurement.html) [meadmetals](https://www.meadmetals.com/blog/importance-of-as9100-certified-material)
Procuring aerospace-grade titanium involves significant cost considerations beyond simple raw material pricing. According to current industry benchmarks, titanium plate used in aerospace applications can see significant price fluctuations based on market demand and supply chain complexity.
It is vital to understand that fully certified AMS 4911 titanium plate typically commands a higher price than standard industrial-grade (ASTM B265) titanium. This price difference, often ranging from 20% to 40% higher, directly reflects the added investment in rigorous quality control, mechanical testing, chemical composition verification, and the necessary administrative cost of achieving and maintaining aerospace certifications. Procurement managers should view this premium as an investment in safety and liability mitigation, rather than a mere expense.
While Grade 5 (Ti-6Al-4V) is the "workhorse" of the aerospace industry, design requirements for damage tolerance have driven the adoption of high-performance variants.
For applications where fracture toughness and resistance to crack propagation are paramount—such as in landing gear components, rotor hubs, and pressurized structures—Grade 23 (Ti-6Al-4V ELI - Extra Low Interstitials) is the industry standard. By significantly restricting the levels of interstitial elements like oxygen, carbon, and nitrogen, Grade 23 achieves superior ductility and fracture toughness compared to standard Grade 5.
