C specified CTE alloys - CE alloys
Technical characteristics
Alloys with a given thermal coefficient of linear expansion (made on the basis of iron and Nickel) подразделяютcz into three groups: group 1 — has the minimum coefficient (<3 • 10-6 K-1), rarely used. Alloy 29NK, 42N, 18ХТФЮ, etc. have an average coefficient (3 • 10-6 to 12 • 10-6 K-1) and high (12 • 10-6 to 27 • 10-6 K-1). They are used mostly for junctions of electrical contacts with glass and ceramics. The third group consists 75GND, 22НХ etc., which are used as active components of the thermostatic bimetallic.
The second group

42N marking means that the alloy contains about 42% Nickel.
