1. Introduction
FeCrAl alloys used in a wide range of high-temperature applications.
Constantan [Cu55Ni45] has a low temperature coefficient of resistivity and as a copper alloy, is easily soldered. Other constant-resistance alloys include manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3]and Evanohm.
The Evanohm family of nickel-chrome alloys [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], have high resistance, low temperature coefficient of resistance, low electromotive force (Galvani potential) when in contact with copper, high tensile strength, and also are very stable with regards to heat treatment.
