Characteristics of the alloy 80НМВ-ВИ

The grade of the alloy 80NMV-VI of the precision group refers to alloys of a precision group with a temperature-specific linear expansion coefficient (1,000,000 * TLCL in the temperature range -70 +550 ºC to 11−11.4 [1 / ºC]), which is used for soft glass connections. This group of alloys contains highly alloyed alloys. The main component of precision alloys are alloys based on iron, copper, nickel, niobium and cobalt. A precision alloy is a metal alloy that possesses physico-mechanical unique characteristics (magnetic, elastic, thermal, electrical, etc.), or an alloy that combines a number of properties due to chemical. Composition, thoroughness of processing, manufacturing and the absence of a variety of impurities. The melting point. Alloy is equal to 1450 ° C.
