Apart from iron-nickel alloy Invar , Kovar and permalloy , but also include the following alloys : (1) 68Fe +27 Ni +5 Mo and 53Fe +42 Ni +5 Mo, has a high thermal expansion coefficient , can be used bimetal thermostat , heat exchanger , and a variety of temperature adjusting means . (2) 46Ni +54 Fe, called on Low Alloy Steel Electrodes behalf of platinum , platinum same coefficient of expansion , has good corrosion resistance, in some cases can be used instead of platinum . (3) 42Ni +58 Fe, vacuum sealing can be used instead of platinum wire. (4) 36NJ +12 Cr +52 Fe, is a constant elastic alloys , thermo-elastic coefficient is equal to zero , commonly used for hair clips , watches balance wheel and precision instrument parts . Melting ingots , pressure processing .
