It contains rare-earth additions for increased resistance, especially under conditions
of frequent switching or wide temperature fluctuations.This is an excellent
choice for heating elements operating at a temperature up to 1100 C, which include
the majority of household appliances and other heating elements operating
in an average range of temperatures, and where the exceptional properties of Resistohm
80 are not necessary.
Its applications include all sorts of heating elements and resistances (toasters
elements, potentiometer resistances and other household and industrial appliances).
