Electrical Resistance and Thermocouple Alloys,ls also serve other purposes, for example, the nickel-chromium alloys which are used in structural applications. 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.

Controlled-Expansion and Controlled-Modulus Alloys, 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.

Electrical Resistance and Thermocouple Alloys, very low nickel content, certain groups are used most widely and these are the materials which will be discussed in this chapter. 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

Book 1971. Low-alloy and constructional nickel-containing steels have been excluded on two grounds. To do them justice would require excessive space and, in addition, their applications differ generally from these of the materials under discussion. On the other hand, nickel-containing stainkss steels have be
