Service Properties and Applications for Nickel Alloy Resistance Wire Header

Material Designation Symbol Number UNS Other Name Service Properties Applications
NICKEL CHROME
Ni Cr 8020 2.4869 NO 6003 Ni Cr 80/20 Contains long life additions making it eminently suitable for applications subject to frequent switching and wide temperature fluctuations. Can be used at operating temperatures up to 1150 °C. Control resistors, high temperature furnaces, soldering irons.
Ni Cr 6015 2.4867 NO 6004 Ni Cr 60/16 A Ni/Cr alloy with balance mainly Iron, with long life additions. It is suitables for use up to 1100°C, but the higher coefficient of resistance notes it suitable only for less exacting applications than 80/20. Electric heaters, heavy duty resistors, electric furnaces.
CUPRO NICKEL
Cu Ni 44 2.0842 - Hecnum Medium resistivity combined with low temperature coefficient of resistance makes it ideal for resistors. It is suitable for temperatures up to 400°C. Thermocouples, resistors, heating wires and cables.
Cu Ni 30 Mn 2.0890 - - High resistance to oxidation and chemical corrosion. Maximum working temperature is 500°C Resistors, heating cables and detectors for fuses.
Cu Ni 23 Mn 2.0881 - - High resistance to oxidation and chemical corrosion. Maximum working temperature is 500°C Resistors, heating cords and mats.
Cu Ni 10 2.0811 - Alloy 90 High resistance to oxidation and chemical corrosion. Maximum working temperature is 400°C Low value resistors, heating wires and mats.
Cu Ni 6 2.0807 - Alloy 60 Characterised by low resistivity. High resistance to oxidation and corrosion. Maximum operating temperature is 300°C Tube electrical welding fittings, ribbons used for heating of bimetals.
Cu Ni 2 2.0802 - Alloy 30 Characterised by low resistivity. High resistance to oxidation and corrosion. Maximum operating temperature is 300°C Tube electrical welding fittings, ribbons used for heating of bimetals.
IRON CHROME ALUMINIUM
Cr Al 20-5 1.4767 K 92400 ICA 135 A ferromagnetic alloy which can be used at temperatures up to 1300°C. Should be operated in dry surroundings to avoid corrosion. Can become embrittled at high temperatures. Heating elements of high temperature furnaces and radiant heaters.
Cr Al 25-5 1.4765 K 92500 ICA 145 Can be used in operating conditions up to 1350°C, although can become embrittled. Heating elements of high temperature furnaces and radiant heaters.
