, UNS: K94100 , *Trade name of Special Metals Group of Companies
A Nickel-Iron, low expansion alloy containing
42% Nickel. It has a low and nominally constant coefficient
from room temperature to about 300°C. Applications include
semiconductor lead frames, thermostat rods, various glass to
metal seals and television tubes.

The Nilo alloys are usually used
in the annealed condition (residual cold work distorts the
coefficients of thermal expansion).
