GENERAL CHARACTERISTICS

Wire and a circle of mark 79НМ are made from high-nickel permalloy. Permaloy — a material based on nickel and iron with significant magnetic permeability in weak fields. There are low-nickel (40−50% Ni), and high-nickel permalloy (72−82% Ni)). To enhance the magnetic permeability, they are doped with elements such as copper, manganese, etc. Each of the groups has a certain degree of manifestation of electromagnetic properties. Due to the significant nickel content, the 79HM alloy has a high electrical resistance and corrosion resistance. The permalloy is melted in vacuum or under protection of argon. The wire and the circle are produced in a cold-rolled manner with final annealing, to optimize the electromagnetic properties.

APPLICATION

Mark 79HM has a min magnetostriction. Used in high-precision instruments with stable operation in an alternating electromagnetic field. The electrical resistance of the 79HM brand varies only within 5%, depending on the strength and direction of the fields. Serves for the manufacture of transformer plates, parts for recording magnetic heads, cores of compact transformers, contactless relays.
