Zinc-Nickel Brush Plating: Important AMS2451/9 Solution

Summary for zinc-nickel brush plating Discussion

Zinc-nickel brush plate solution is the focus of this thread, where Jonathan Lelah asks whether any low-hydrogen-embrittlement brush plating process for zinc-nickel is certified to AMS2451/9, or at least meets its requirements. He notes that the only product he knows of is Sifco 4018/5970, but that it is certified to a Boeing specification rather than AMS because of the ASTM F519 test specimen type used: AMS calls for Type 1a.1, while Boeing uses Type 1a.2. The excerpt provided contains only the question and does not show any replies, so no alternate products, confirmations, or corrections are available here. Based on the source shown, the practical takeaway is simply that the asker is seeking a compliant low-hydrogen-embrittlement zinc-nickel brush plating solution and has identified a possible near-match that may not fully satisfy AMS2451/9 certification requirements.
