Description
Alloy is a 36% nickel-iron alloy possessing a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 204^oC. This is one of the controlled expansion alloys. It has an expansion rate roughly 10% that of standard carbon steels.

Applications
This alloy has been used for applications where dimensional changes due to temperature variation must be minimized such as in radio and electronic devices, aircraft controls, optical and laser system, etc. Alloy has also been used in conjunction with high expansion alloys in applications where a motion is desired when the temperature changes, such as in bimetallic thermostats and in rod and tube assemblies for temperature regulators.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 8.05
Thermal conductivity [W/m.K]: 72.0
Electric resistivity [Ohm mm²/m]: 0.49
Specific heat capacity[J/g.K]: 0.12
Curie Temperature: 279^oC

Coefficient of Linear Thermal Expansion 10^-6 ^oC^-1

20-93^oC	20-149^oC	20-260^oC	20-371^oC
1.30	2.11	4.18	7.60

Annealing
Heat to 790^oC and hold at heat 30 minutes per inch of thickness, then air cool. Heating to temperatures above 538^oC relieves the presence of cold work stresses. The higher the temperature, the lower the annealed hardness, as shown in the following table.

Air Treatment Temperature (^oC) vs. Hardness Rockwell B

650^oC	815^oC	980^oC	1040^oC
87/88	77/78	70/71	66/68

Hardening
To assure optimal dimensional stability, heat to 815^oC, hold at heat for 30 minutes per inch of thickness, water quench, reheat to 315^oC holding one hour at heat, then air cool. To promote temporal stability (when necessary), alloy has been aged for 24 to 48 hours at 93^oC.

Forging
Hot forming temperature: Heat to 1180^oC rapidly and cool rapidly following working. Do not soak at temperature.

Machinability
This alloy can be machined employing most common methods. It is known to produce "gummy" chips and is best machined at slow speeds with positive and constant feeds.

Corrosion Resistance
While not designed to be used in corrosive environments, this alloy will withstand some exposure to many mild atmospheres and conditions.

Welding
All common joining techniques can be successfully employed here. When a filler metal is required, it is suggested to use a similar composition alloy, available from the manufacturer.

Cold working
This alloy can be cold upset and swaged successfully.

Grinding and Polishing
A silicon carbide wheel is desirable, preferably a soft wheel which will wear without loading. For finish grinding, a satisfactory grade to start with is No. 80 grit.
