DMS 1870 - 6Al-6V-2Sn Titanium Alloy Forgings (Boeing/Douglas, Annealed)
DMS 1870 is the Boeing / McDonnell Douglas Material Specification for 6Al-6V-2Sn Titanium Alloy forgings in the annealed condition. The DMS series specifications were originally developed by McDonnell Douglas and became part of the Boeing family after the 1997 merger. DMS 1870 covers the supplier qualification, testing, and traceability requirements for 6Al-6V-2Sn titanium forgings used on Boeing and Douglas aerospace programs.
Forgings per DMS 1870 are called out on Boeing and Douglas engineering drawings for high-strength titanium forged structural components where the superior grain flow and fatigue properties of forgings are required for primary structure service.
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.
