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-quantity miscellaneous hardware, but usage is not limited to such applications. Certain processing procedures and service conditions may cause these products to become subject to stress-corrosion cracking; ARP982 recommends practices to minimize such conditions.
AMS4993E is a Five Year Review and update of this specification.
