Typical Applications
With a nominal composition of 37% of nickel, 18% of chromium, 2% of silicon and with an addition of rare earths, Resistohm 40 is suitable for a large field of domestic heating applications, and particularly when use temperature is not too high and that cost is a vital factor.

Its high temperature coefficient allows it a speeder rise in temperature than the other NiCr.

The most frequent use fields are:

• Heating accumulators

• Convectors

• Heaters

Its maximum operating temperature is 1050°C.

When an electric furnace must operate in a carburing or semi-reducting atmosphere, this alloy has dictincts advantages compared to the other Nickel-Chromium which have a higher percentage of nickel.
