47ND sheet, strip, foil
Sheet, strip, foil
Technical characteristics
47ND strip, sheet, foil are manufactured out of precision alloys with a defined linear expansion thermal coefficient (TCLEx1000000 at a temperature range -70 +440ºC not higher than 9−11 [1/ºC]). This material is used for making springs, hermetically sealed contacts reed relay, joining with mica and ceramics, junction with a soft glass.
It possesses unique physical, mechanical characteristics (magnetic, elastic, heating, electrical etc.). Precision alloys differ with an accuracy of chemical composition, a preciseness of manufacture, processing, and absence of residual elements. Its temperature of melting is 1450 °C. Precision alloys are the high-doped alloys that manufactured on a basis of iron, nickel, copper, mangan, cobalt.

welding is possible at heating to 100−120°С and last heat treating |
| hardly weldable |
in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, heat treating (annealing) after welding |
| weldable without stint |
welding is done without further heat treating or previous heating |
