Some of the materials also serve other purposes, for example, the nickel-chromium alloys which are used in structural applications. Similarly, the 55% copper-45% nickel

Similarly, the 55% copper-45% nickel alloy is used not only as a resistance material in instrumentation but also as a thermocouple alloy which, of course, is a specialized resistance application.

,The Drive to Society in Kant’s , alloy “Invar.” He found also that the addition of 12% chromium produced an alloy having an invariable modulus of elasticity over a considerable temperature range and called this alloy “Elinvar.” Both of these alloys are atill in use. Elinvar will be discussed later.
