The most-used names for this grade.About Controlled-expansion nickel-iron alloys
Controlled-expansion nickel-iron alloys are materials formulated to provide predictable thermal expansion and good dimensional stability. They are used for glass-to-metal seals, electronic packages and precision instruments where limiting thermal mismatch is important.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition
5 elements on file · weight %What this alloy is
Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

≤0,50\n(≤0,03) | |

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred.
Predicted transformation temperatures
Not enough recorded composition to predict a transformation temperature for this grade — missing: C, Si, Cr, Mo.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
