AMS 4911 is the aerospace material specification for titanium alloy 6Al-4V (Grade 5) sheet, strip and plate supplied in the annealed condition.
What AMS 4911 covers
Titanium Industries stocks titanium 6Al-4V Grade 5 sheet and titanium 6Al-4V Grade 5 plate to AMS 4911.
Material supplied to AMS 4911 is checked with the acceptance tests the specification requires: bend test, chemical composition, microstructure, surface contamination, tensile properties and, where required, ultrasonic inspection.
AMS 4911 cross-references AMS 2631, AMS 6932, AMS-T-9046, ASTM F1472, ASTM B265 Grade 5 and EN 10204 3.1. Tensile requirements vary with orientation, section thickness and engineering requirements, so always check the specification itself.
