DMS 1570 - 6Al-4V Titanium Alloy Bars and Billets (McDonnell Douglas/Boeing)
DMS 1570 is the McDonnell Douglas / Boeing Material Specification for 6Al-4V Titanium Alloy bars and billets. This specification covers the procurement and quality requirements for 6Al-4V titanium bar stock used in Boeing and McDonnell Douglas aerospace programs requiring bars to the DMS designation rather than the SAE AMS 4928 designation.
Material produced per DMS 1570 is chemically and mechanically equivalent to AMS 4928 bars and billets, but is qualified to the Boeing/McDonnell Douglas supplier and testing requirements. It is commonly cross-referenced with AMS 4928 on engineering drawings that specify either designation as acceptable.
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.
Applications of DMS 1570 6Al-4V Titanium
