80NMV-VI precision alloy is a non-magnetic material with a coefficient of thermal linear expansion (TKLR 11-11.4 [1/ºC] between minus seventy degrees and +550ºC) and is used to seal the junction with glass. Melting point of the alloy = 1450 °C. Refers to the group of highly alloyed precision alloys with unique physical and mechanical characteristics (elastic, magnetic, thermal, electrical), due to the verified chemical composition, the absence of impurities, precision manufacturing and processing. The main part of precision alloys is made on the basis of iron and nickel.
