NOTES: 1/ If brazing alloys of similar chemistry and mechanical properties not listed under an F-number group are to be used, they may be considered as a group upon approval. 2/ Brazing alloys that are not listed in this table but that are listed in NAVSEA 0900-LP-001-7000 are considered to be part of the same F-group in this table as they are in NAVSEA 0900-LP-001-7000, provided any additional requirements for such filler material types that may be specified by NAVSEA 0900-LP-001-7000 shall also apply here. 3/ See 8-2 for guidance on filler material characteristics. 4/ Category F-103 brazing alloys shall not be used on ferrous alloys (P-101), nickel base alloys (P-110 and P-111), copper-nickel alloys containing more than 10 percent nickel (P-107), or stainless steels (P-102). 5/ Category F-102/F-102A brazing alloy grades containing 2 percent or more nickel shall be used for any joint where one or both of the materials joined is stainless steel. Other Category F-102/F-102A grades may be used on nickel plated stainless steel, when approved. 6/ Grades IV, V, VII, and VIII as specified in QQ-B-654 and grades BAg-1, BAg-1a, BAg-2, and BAg-3 as specified in AWS A5.8 contain cadmium and are not intended for new design, unless approved by NAVSEA.
