GENERAL CHARACTERISTICS

The sheet and the 79MNM tape 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

The 79HM alloy has a min magnetostriction. The sheet and the 79MNM tape are 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.

BUY AT THE BEST PRICE

The company «_" realizes the sheet and ribbon of the brand 79NM in a wide range from the manufacturer. The optimal price category and full compliance with the requirements of the technical documentation will ensure the reliability and cost-effectiveness of production Individual work with each customer regardless of the purchase price is the motto of our work since the company was founded .
