Nickel Wire

MWS offers many nickel based alloys that are used in RTD sensors, resistors, rheostats, voltage control relays, heating elements, potentiometers, and other components. Engineers design around properties unique to each alloy. These include resistance, thermoelectric properties, high tensile strength, and coefficient of expansion, magnetic attraction, and resistance to oxidation or corrosive environments. Wires can be provided as uninsulated or with film coating. Most alloys can also be made as flat wire.

High Strength Nickel Alloys

Monel 400

This material is noted for its toughness over a considerable range of temperatures, and has excellent resistance to many corrosive environments. Monel 400 can be hardened only by cold-working. It is useful at temperatures up to 1050° F, and has very good mechanical properties at temperatures below zero. Melting point is 2370-2460⁰ F.

Inconel* 600

Resists corrosion and oxidation to 2150⁰ F. Provides springs with high resistance to corrosion and heat up to 750⁰ F. Tough and ductile down to -310⁰ F is nonmagnetic, easily fabricated and welded. Used for structural parts, cathode ray tube spiders, thyratron grids, sheathing, tube supports, spark plug electrodes.

Inconel* X-750

Age hardenable, nonmagnetic, corrosion and oxidation resistant (high creep-rupture strength to 1300⁰ F). Heavy cold working develops tensile strength of 290,000 psi. Stays tough and ductile to -423⁰ F. Resists chloride-ion stress-corrosion cracking. For springs operating to 1200⁰ F and tube structural parts.
