Feature
Precision alloy 80НМВ-VI applies to non-magnetic materials with coefficient of thermal linear expansion (CTE 11−11.4 [1/ºC] between minus seventy degrees and +550ºC), is used for hermetic sealing with glass. The melting point of the alloy = 1450 °C. Refers to a group of high alloy precision alloys with unique physical and mechanical properties (elastic, magnetic, thermal, electric), owing to the exact chemical composition, purity, precision manufacturing and processing. The main part of precision alloys is based on iron and Nickel.
