DMS 2285 - 6Al-4V Titanium Alloy Tubing (McDonnell Douglas/Boeing)
DMS 2285 is the McDonnell Douglas / Boeing Material Specification for 6Al-4V Titanium Alloy tubing. This specification covers seamless and welded titanium tubing used in Boeing aircraft hydraulic systems, fuel system plumbing, and structural tubing applications where the Boeing engineering drawing requires the DMS designation.
Tubing per DMS 2285 meets the same dimensional and mechanical requirements as AMS 4965 tubing, with the additional Boeing-specific qualification and traceability requirements. Both specifications are routinely cross-referenced on Boeing drawings for hydraulic and fuel system lines.
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.
