Relevance
Precision 47NHR brand alloy is alloy with minimal thermal coefficient of linear expansion (coefficient of linear expansion to 8,5−11 [1 / ºC]) over the temperature range -70 + 330ºC. Such an alloy is important for tight junction with glass or mica. Group precision alloys based on iron and nickel is allocated for the exclusive physical and chemical properties (magnetic, thermal, elastic, electrical), through the composition accuracy, and quality of the finish processing, the absence of unnecessary impurities.
