Characteristics of the alloy.

Precision brand 33NK alloy with an average value of temperature coefficient of linear expansion is designed to connect the glass 72−4, mica, ceramics. 33NK alloy with an average value of the thermal linear coefficient EXT. (6,0−9,0)·10−6 deg-1 within the temperature range of from -70 to + 470 °C. Such grades as 33NK, 33NK-VI for use in the upgraded or newly created technology is not allowed with 01.01.91 g. the melting point of the alloy is 1450 °C.

Precision alloy is a metal alloy which has physical and mechanical unique characteristics (magnetic, elastic, thermal, electrical, etc.). Precision alloy has a number of properties characterizing the accuracy of the chemical. composition, thoroughness manufacturing and processing, the absence of various impurities. This category contains, as a rule, high-alloyed alloys. Precision alloy is mainly produced based on iron, Nickel, copper, niobium, cobalt. This group of alloys used in precision machine tools, in the production of various precision electronic devices, innovative technologies and laser equipment, household appliances, production of metrological and measuring instruments.

weldability limited — welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment
konovalivka in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding.
Welded without any restrictions — welding is carried out without further heat treatment and pre-heating.
