Technical characteristics

49K2 °F wire is used for a junction with soft glass. It is made of precision alloy with a defined linear expansion thermal coefficient x1000000 at temperature range -70 +330ºC and not higher than 8,5−11 [1/ºC]. This precision alloy possesses rare physical, mechanical characteristics (magnetic, elastic, heating, electrical etc.) It is characterized with an accuracy of chemical composition, a preciseness of manufacture, processing, and absence of residual elements. It is high-doped alloy. Precision alloys are manufactured on a basis of iron, nickel, copper, mangan and cobalt. This group of alloys is used in modern innovative technologies, at manufacturing the electronic units, household appliances, details of laser techniques and metrologic-measuring equipment.

Percentage composition of alloy:
