C specified CTE alloys - CE alloys
Alloys with a given thermal coefficient of linear expansion (produced on the basis of iron and Nickel) подразделяютcz into three groups: 1-I group andhave a minimum coefficient of (<3 • 10-6 K-1), is rarely used. Alloy 29NK, 42N, 18ХТФЮ and others have the average coefficient (3 • 10-6 — 12 • 10-6 K-1) and high (from 12 • 10-6 to 27 • 10-6 K-1). They are used in mostly for junctions of electrical contacts with glass and ceramics. The third group consists 75GND, 22НХ and etc., used in as the active components of the thermostatic bimetallic.
The second group
The percentage «Kovar», 29NK GOST 10994−74
42N marking means that the alloy contains about 42% Nickel.
