GMS 3101 - 6Al-4V Titanium Alloy Bars (Goodrich/Collins Aerospace)
GMS 3101 is the Goodrich (now Collins Aerospace) Material Specification for 6Al-4V Titanium Alloy bars. This specification covers the procurement requirements for 6Al-4V titanium bar stock used in Goodrich / Collins Aerospace nacelle, thrust reverser, and landing gear structural components where the GMS designation is called out on engineering drawings.
Material per GMS 3101 meets Goodrich/Collins Aerospace’s supplier qualification requirements in addition to the base AMS chemistry and mechanical property requirements. Collins Aerospace (formerly UTC Aerospace, formerly Goodrich) is one of the world’s largest aerospace component manufacturers, supplying nacelles, actuation systems, and landing gear to Boeing, Airbus, and military programs.
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.
