Summary for nickel manganese recipe Discussion
Nickel manganese recipe is the focus of this thread, but the practical answer is that the alloy may not be a commercially viable plating choice for the stated goal. Kevin Kelly asked for a nickel-manganese deposit recipe and its strength versus temperature because his company plates nickel heat exchangers and wants better high-temperature strength. In response, the answerer noted that Brenner’s "Electrodeposition of Alloys" does mention nickel-manganese plating, but the quick read suggested it may not be commercially viable. The answerer also said they did not fully understand the application, but if the goal is electroforming nickel products, nickel-cobalt alloys would likely be a better direction to investigate. No recipe or temperature-strength data was provided in the thread, and the advice leans toward exploring nickel-cobalt instead of nickel-manganese.
Q. Our company plates nickel heat exchangers. We would like to plate our products from a nickel alloy with better high temperature properties (particularly strength). I’ve been told nickel-manganese might be the best bet. What’s the recipe for nickel manganese and what is the strength as a function of temperature?

A. Brenner’s “Electrodeposition of Alloys” admits the existence of such a plating, but a quick read didn’t seem to imply that it was commercially viable. I admit to not quite understanding your situation, but if you are electroforming nickel products, I think you’d be better off looking into nickel-cobalt alloys.
