The addition of tin displays spinodal strengthening via sub-microscopic chemical composition fluctuations. Copper Nickel Tin Alloy are used subsea where bearing performance, non-magnetic, low-fouling, anti-galling or high strength properties are required. Example applications include subsea manifold and ROV lock-on devices and seawater pump components, stems, bushes and bearings, drill components, subsea connectors and lifting nuts. Copper-Nickel-Tin Alloy, Bars and Rods 77Cu - 15Ni - 8Sn Solution Annealed, Cold Finished and Spinodal Hardened (TX TS) AMS4597 This specification covers a copper-nickel-tin alloy in the form of bars and rods. Copper alloy 729 Rod is a perfect alternative to nickel alloys, aluminum bronzes, and beryllium copper. C729 ToughMet alloys are anti-galling, free of lead and beryllium, and show excellent corrosion and stress corrosion cracking resistance in seawater applications.
