Aperam Resistohm® 80 Resistant Alloys-Nickel Chromium Alloys
Categories: Metal; Nonferrous Metal; Nickel Alloy

Material Notes: Chemical composition of 80% Nickel and 20% Chromium makes of him the most well-known resistive alloy. It contains rare-earth additions for increased oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. Resistohm 80 gives extraordinary performances at temperatures up to 1200°C and will be operational at those high temperatures under the most exacting conditions. It is the first choice for all heating elements operating at high temperatures or for each element subject to important heating and cooling cycles, as well in the domestic as in the industrial applications. Electric furnaces, high temperature elements, heating batteries are among others typical applications of this alloy. This nuance presents an excellent resistance to hot flow and a very good dimensional stability of the spirals with successive heating cycles. In an alternated oxidising/reducing atmosphere, Resistohm 80 can be subject to the “green rot”. This document describes requirements for alloys to be used as components in the manufacture of bonded multicomponent thermostat metal strip.
