The alloys in DIN 17742 are specifically engineered for their thermo-mechanical behavior. Their nickel content is carefully balanced to achieve a specific coefficient of thermal expansion (CTE) that, when bonded to a high-expansion side (e.g., manganese-copper or nickel-chromium-iron), creates predictable bending curvature per degree of temperature change.
Typical applications in automotive thermostats or refrigerator temperature controls rely on the reproducibility guaranteed by this standard.
