Characteristics of alloy

47ND alloy relates to precision alloys with a defined linear expansion thermal coefficient (TCLEx1000000 at a temperature range -70 +440ºC not higher than 9−11 [1/ºC]). Used in making springs, hermetically sealed contacts reed relay, joining with mica and ceramics, junction with a soft glass.

This precision alloy possesses unique physical, mechanical characteristics (magnetic, elastic, heating, electrical etc.) Precision alloys differ with an accuracy of chemical composition, a preciseness of manufacture and processing, and absence of residual elements. They are the high-doped alloys. Precision alloys are manufactured on a basis of iron, nickel, copper, niobium, cobalt. A temperature of melting is 1450 °C.

Type Description
limitedly weldable 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

Mechanical properties at a temperature 20 °C.
