AMS 4730 UNS N04400, widely known as Monel 400 nickel‑copper alloy wire, is a single‑phase solid‑solution corrosion‑resistant alloy. The AMS 4730 specification governs wire products starting from 0.002 inch (0.05 mm) diameter and above, designed for service in harsh industrial and marine environments. Monel 400 wire features outstanding ductility. It delivers reliable corrosion performance covering mildly oxidizing, neutral, and moderately reducing service conditions, and shows excellent stability when exposed to seawater and non‑oxidizing chloride‑rich solutions. Its mechanical strength can only be enhanced by cold working; heat treatment will not harden this alloy. The material retains good toughness and structural integrity across a broad temperature span from sub‑zero up to 800 °F. |  |
As a trusted Chinese nickel‑copper alloy manufacturer, ZYTC Alloy supplies AMS 4730 compliant Monel 400 wire to global clients engaged in chemical processing, offshore engineering and marine equipment manufacturing. We provide diverse wire diameters, tempers and spooling options to match customer drawing and project requirements.
