DMS 1888 - 6Al-4V Titanium Alloy Forgings (McDonnell Douglas/Boeing)
DMS 1888 is the McDonnell Douglas / Boeing Material Specification for 6Al-4V Titanium Alloy forgings. This specification covers the procurement and quality requirements for titanium forgings used in Boeing structural assemblies, including bulkheads, rib forgings, and frame forgings on commercial and military aircraft programs.
Forgings per DMS 1888 are qualified to Boeing NDT, mechanical test, and traceability requirements in addition to the standard AMS chemistry and property requirements. The DMS designation is required on Boeing engineering drawings that specifically call out this specification rather than the AMS equivalents.
6Al-4V is recommended for use at temperatures from -350° to 750°F (-210° to 400°C). Applications outside this temperature range are possible in certain situations. The alloy is weldable. Complex shapes can be made via hot forming. It machines like an austenitic stainless steel.
