Relevance
Precision 32NK-VI alloy with a predetermined thermal coefficient of linear expansion is used for parts with a polished surface, or for connection with a soft glass has a temperature coefficient of linear expansion coefficient of linear expansion 1 1,5x10−6 / ° C in the temperature range from -60 to + 100 ° FROM. The alloy has unique physical and technical characteristics (magnetic, thermal, elastic, electric), thanks to the accuracy of the composition, manufacture and thoroughness of treatment, lack of unnecessary impurities. Such alloys are melted in a special induction furnaces, and then subjected to pull the shoes ingots or rental.
application
The scope of precision instrumentation, innovative technologies, production of precise electronic sensors, home appliances, laser optics, metrology measuring equipment, memory components of computers, microphones core, magnetic antennas.
