33NK (ribbon, circle, wire)

Technical Characteristics

Precision alloys are mainly made from chromium, nickel, copper, niobium and cobalt. They are high-alloys with rare physical characteristics: magnetic, elastic, thermal and electrical. These unique qualities are due to the precision of the chemical composition, the thoroughness of manufacturing and processing and the absence of impurities. This group of alloys is used in precision machine tool engineering, in the production of various precision electronic devices, in innovative technologies and laser equipment, in household appliances, in the production of metrological and measuring devices. Grade 33NK serves for connection with glass C72-4, mica, ceramics. This alloy has an average value of the thermal coefficient of linear expansion of 6 - 9x10-6/ C° (t° from -70 to + 470°C). The melting point of the alloy is 1450 °C.
