Monel Wire - R405 Series Copper Alloy Wire for Valve Inserts and Pump Connectors is a free-machining nickel-copper alloy wire engineered for precision mechanical and threaded applications in corrosive industrial environments. Based on the Monel 400 chemistry, Monel R405 includes a controlled sulfur addition to improve machinability without compromising corrosion resistance.
This alloy wire is especially suitable for use in automated manufacturing of valve seats, threaded inserts, and pump connectors where tight tolerances, surface finish, and chemical durability are essential. It maintains structural integrity under high-flow, pressure, and exposure to acids, alkalis, and seawater.
Free-machining formulation with sulfur content up to 0.025%
Excellent corrosion resistance in aggressive chemical and saline conditions
Ideal for threading, turning, and high-speed CNC machining operations
Non-magnetic and structurally stable at elevated temperatures
Supplied in precision diameters for valve assemblies and sealing components
Threaded valve inserts and pump shaft connectors in chemical plants
Fast-turn CNC components for marine and offshore fluid systems
Gland rings, pressure sleeves, and plug interfaces in rotating assemblies
Machined electrical connectors and contact inserts in corrosive environments
Instrument fittings and tubing ends for process and flow control equipment
Manufactured to ASTM B164 / UNS N04405 (R405)
Typical composition: Ni ~66%, Cu ~29%, S ~0.025%
RoHS / ISO9001 / REACH compliant production
100% tested for machinability, surface finish, and dimensional accuracy
Supplied with COA, MTC, and optional third-party inspection
