Fecral Alloy 815 Resistohm 135 Stablohm 812 0cr23al5 Heating Resistance Strips for Industry Resistor
Resistance wire is a type of high resistance electrical wire. The wire resists the flow of electricity, and converts the electrical energy into heat.
Application for resistance wire includes resistors, heating elements, electric heaters, electric ovens, toasters, and many more.
FeCrAl, a family of iron-chromium-aluminum alloys (TANKII APM, A-1, D and AF etc.) used in a wide range of resistance and high-temperature applications is also used in the form of resistance wires.

4. Typical Applications
Resistohm 135 is a ferritic alloy of the FeCrAl family, which can be used as heating element of resistance up to 1200°C.
Resistohm 135 must be used in a dry environment in order to avoid rust because this is not a stainless alloy.
Elements realised in Resistohm 135 have an excellent life time in a sulphurous environment, and particularly when atmosphere is also oxidizing.
Resistohm 135 is normally used in top cookers with ceramics, pottery furnaces
elements, and tubular elements.
Because of its resistance to carbonaceous atmospheres, Resistohm
135 is chosen for the production of cigarette lighters and fuel
burners elements.
FAQ
