Titanium Alloy, Blended Powder Compacts, Sintered, 6Al 4V
This specification covers a titanium alloy in the form of compacts produced by pressing and sintering a blend of elemental titanium powder and aluminum-vanadium alloy powder. These compacts have been used typically for light weight nuts ('B-nuts') used for connecting fluid lines to fittings and to equipment, and for other small high-quality miscellaneous hardware, but usage is not limited to such applications.
