AMS 4918 - 6Al-6V-2Sn Titanium Alloy Sheet and Strip (Annealed)
AMS 4918 is the specification for 6Al-6V-2Sn Titanium Alloy sheet and strip in the annealed condition. The 6Al-6V-2Sn alloy (Ti-662) provides higher strength than 6Al-4V through heat treatment and is used in aerospace airframe applications where maximum structural efficiency is required.
Sheet and strip per AMS 4918 are used in aerospace structural skins, bulkhead panels, and formed components on military aircraft and missiles requiring the higher strength capability of the 6Al-6V-2Sn alloy system compared to the standard 6Al-4V grade.
6Al-6V-2Sn titanium alloy offers higher strength than 6Al-4V in the solution treated and aged condition, making it the preferred choice for the most highly stressed aerospace structural applications where standard 6Al-4V STA cannot meet design requirements.
