Safety data sheet 1 product and supplier identification. Constantan alloy distributor in the usa a metal source llc is a distributor of constantan alloy which is an alloy composed of 55 copper and 45 nickel developed on the improvement of constantan. Resistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance temperature curve over a wider range than the manganins. Its main feature is its resistance which is constant over a wide range of temperatures.

Constantan is used in applications such as thermocouples power resistors shunts and wire wound precision resistors. Technical data sheet constantan constantan is a copper nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Other alloys with similarly low temperature coefficients are known such as manganin cu86mn12ni2. Recipe edit edit source 4.

Copper nickel alloy resistance alloy supplier. Expanded constantan sheet heater is made from constantan a copper nickel resistance alloy that is also called as cupronickel. It offers high electric resistivity and is commonly used in resistance heating applications over a broad temperature ranges. Known for its high electrical resistivity and its ability to perform consistently despite changes in temperature constantan is also widely used throughout the.

We supply expanded constantan sheet as an electric heater. Ferry hecnum telconstan constantan general description. Its main feature is the low thermal variation of its resistivity which is constant over a wide range of temperatures other alloys with similarly low temperature coefficients are known such as manganin cu 86 mn 12. Careful control of melting and conversion practices results in a very low level of pinholes at ultra thin thicknesses.

It is paired with iron copper and chromel to form types j t and e thermocouples respectively. It is not used for anything currently except to store constantan plates. Constantan is a proprietary name unreliable source for a copper nickel alloy also known as eureka advance and ferry. Constantan is a copper nickel alloy usually consisting of 55 copper and 45 nickel.
