The regulated index of linear expansion, in a fairly wide range of temperatures (from minus seventy to plus three hundred and thirty degrees Celsius) for such a precision material as the 47HXR alloy ranges from eight and a half to eleven units per degree. Due to such a feature, such raw materials are suitable for use in different climatic conditions, in the manufacture of highly accurate measuring instruments that do not respond to temperature fluctuations by changing the dimensions.
