Precision 47ND alloy (47ND-VI) to specify the non-magnetic alloys having a temperature coefficient of linear expansion (coefficient of linear expansion in a temperature range of -70 + 550ºC not higher than 9.11 [1 / ºC]), which is used for sealing the glass compound. The melting point of the alloy is 1450 ° C. It belongs to a group of precision alloys, which possess unique physical and mechanical properties (thermal, elastic, magnetic, electrical, and so on. P.), Combine a number of qualities, due to the accuracy of chemical. composition, manufacturing care and treatment, a lack of impurities. This group includes high-alloy materials. The main part is made of precision alloys based on iron, copper, nickel, manganese and cobalt.
