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.
