Basic properties
Precision alloy 52H (52H-VI) with high magnetic permeability and saturation induction 1,5 T belongs to alloys with a given thermal coefficient of linear expansion (TKLR in the temperature range between minus seventy degrees and +550ºC) and is used for sealed 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 produced on the basis of iron and nickel.
