Monel R405 Copper Alloy Wire - Machinable Alloy Wire for Instrumentation Terminals is a free-machining nickel-copper alloy wire designed for applications requiring superior corrosion resistance and efficient automated processing. Based on the Monel 400 composition but with added sulfur to enhance machinability, R405 is especially suitable for electrical connectors, sensor terminals, threaded components, and precision-machined parts used in marine, chemical, and energy environments.
The copper alloy format ensures improved electrical conductivity and formability while maintaining Monel's hallmark resistance to seawater, acids, alkalis, and industrial corrosives.
Free-machining version of Monel 400 with added sulfur (up to 0.025%)
Excellent corrosion resistance in seawater and acid/alkaline solutions
Suitable for threading, turning, and high-speed automatic machining
Non-magnetic and stable mechanical properties over a wide temperature range
Available in multiple diameters for terminal pins, connector leads, and precision assemblies
Instrumentation terminals and sensor leads for marine equipment
Precision-machined electrical connectors and valve stems
Threaded rods, contact studs, and fastening pins for corrosive systems
Flowmeter and gauge housing components in chemical process control
Machined cable interfaces and low-friction sliding contact elements
Complies with ASTM B164 / ASTM B865 / UNS N04405
Typical composition: Ni ~66%, Cu ~29%, S ~0.025%
RoHS / ISO9001 / REACH certified manufacturing
100% tested for machinability, surface quality, and dimensional precision
COA, MTC, and optional third-party inspection available upon request
