Iron or chromium alloy resistors are utilized as the core heating element. These heating elements have a high resistance and relatively large voltage is required for the heater to extend over a long interval with a reasonable heat flux. It would be preferable to utilize lower resistance material.
Copper Nickel Alloy Heating - Heating Element AlloyThe benefits of the low resistance and low temperature coefficient of resistance copper nickel alloy heater element are most significant when the heater is one which applies heat over large intervals of subterranean earth and at a temperature level of 600° C. to 1000° C. lntervals of 1000 feet or more can be heated with these heaters.
Other corrosion resistant materials used are a composition of alloy such as copper or titanium. They are most resistant to high temperature and withstand the highly corrosive medium. Recently, specially manufactured alloy such as Inconel® and Incoloy® were introduced for more advanced application. The heating elements are a vital part of the

Nickel Chrome (NiCr) Coil elements, resistance wire Used for corrosion resistant electric heating elements in industrial furnaces with reducing atmospheres. Highly resistant to "green rot" a preferential intergranular oxidation of the chromium that is commonly experienced with other alloys under certain environmental conditions. Highly resistant to oxidation in air.
Overview - Heating Element Design and Calculation - Alloy Overview Heating Element Design and Calculation. To perform as a heating element the tape or wire must resist the flow of electricity. This resistance converts the electrical energy into heat which is related to the electrical resistivity of the metal, and is defined as the resistance of a unit length of unit cross-sectional area.
To perform as a heating element the tape or wire must resist the flow of electricity. This resistance converts the electrical energy into heat which is related to the electrical resistivity of the metal, and is defined as the resistance of a unit length of unit cross-sectional area. The linear resistance of a length of tape or wire may be calculated from its electrical resistivity.

RESISTANCE HEATING ALLOYS AND SYSTEMS FOR RESISTANCE HEATING ALLOYS AND SYSTEMS FOR INDUSTRIAL FURNACES 5 KANTHAL OR NIKROTHAL? There are two main types of electric resistance alloys. Nickel-chromium (e.g. 80 Ni, 20 Cr) called Nikrothal was developed around the beginning of the 20th cen-tury and was soon used as heating element material in industrial furnaces as well as in electric household
The resistance heating alloys can be divided into two main groups, iron-chromium-aluminum (FeCrAl, Kanthal) and nickel-chromium (NiCr, Nikrothal®) based alloys. For lower temperature applications copper-nickel (CuNi, Cuprothal®) and nickel-iron (NiFe, Nifethal) based alloys are also used.
Resistance Heating - an overview ScienceDirect TopicsMetal resistance heating elements for furnaces are normally in the form of wire, strip or tube. Heavy-section low-voltage high-current elements are made with an alloy casting or with corrugated or welded tube. Helically wound wire heating elements are manufactured with wire-to-mandrel diameter ratios of between 3:1 and 8:1, limited by collapse
Resistance heating alloys and resistance alloys Kanthal®Resistance heating and resistance alloys in wire and ribbon (flat wire) form. More information about each type of resistance alloy and resistance heating alloy, such as chemical composition, is available in the datasheet for the respective grade.
Nickel-Chrome Alloy:Most resistance wire heating elements use nichrome 80/20 (80% nickel, 20% chromium) in wire, ribbon, or strip form. NiCr 80/20 is an ideal material because it has relatively high resistance and forms an adherent layer of chromium oxide when heated for the first time.Heating Element Alloys - Everything You Wanted To Know The working of heating elements is based on heating effect of electric current. Heating Element Materials. Most heating elements use Nickel-chrome(NiCr) wire or ribbon as the conductor. Nickel-chrome(NiCr) is an ideal material as it is inexpensive, has relatively high resistance, and does not break down or oxidize in air in its useful temperature range. The performance and life of heating element depend on
