Nilo 52, N14052, 2.4478, Nickel Alloy Strip
Nilo 52 is a Nickel-Iron alloy with a thermal expansion characteristic that corresponds to soft glass. Applications include magnetic reed switches and seals that need controlled linear expansion to about 1000°F.
The alloy is readily formed or deep drawn from a fine grain annealed temper. Joining can be accomplished by conventional welding or brazing techniques. Useful magnetic characteristics can be produced from a continuous strand anneal.
Available Sizes:
Nilo 52 available as strip product in thickness from 0.001” to 0.050” (0.0254 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). The material conforms to UNS N14052.
