General characteristics
50N grade is alloyed heat-resistant alloy on a basis of a hard serum-nickel solution. It has a relatively good permeability in weak fields. It relates to a group of permalloys that are divided by their composition in low-nickel (that contain 50% of Ni) and high-nickel alloys (that contain to 82% of Ni). A quantity of nickel defines magnetic and electric properties. Low-nickel permalloy has a good conductivity in comparison with a high-nickel permalloy. But these alloys have lower corrosion resistance. It is used in manufacture of transformer flakes, magnetic recording heads as an element of precision mechanisms that are exploited in rough conditions. Bar, rod, wire relate to a category of stainless products. Wire is used for welding. Rod is used in chemical, metallurgic, textile industries. Bar is usually has a small cross-section and fixed length.
Relevance
Nowadays, a wire, a rod, a bar of 50N grade have the widest application. These are details of heat-resistant constructions that are used in instrument engineering and energetics. 50N steel is also used in making elastic elements. It is hard-welded and that is why there are made a thermal processing and the last annealing for strengthening the welds.

Ferrum-nickel alloys are smelted in an open arc furnace. Except for analogous alloys, permalloy 50N does not contain phosphorus. It possesses a small variation of electrical resistance (not more than 5%), which are defined by force and existent magnetic orientation. This alloy must be alloyed with such elements as cuprum, mangan, silicon for strengthening of electromagnetic properties,. A smelt is done in a vacuum or inert gas envinronment. Semi-fabricates with minimal thickness are manufactured with a method of cold-rolled stamping with further annealing. It is done for increasing magnetic properties. 50N permalloy has improved features and an increased magnetizing. This alloy is characterized by a significant sensitivity of magnetic properties in relation to external changes.
Application
Due to its small magnetostriction, permalloy 50N is used in mechanical high-accurate units that have stable characteristics in a variable magnetic field. This alloy is used in manufacturing cores of small-sized and high-power transformers, relay actuators, chokes and small details of magnetic circuits. They operate while working at increased induction with a small bias or without it. The high-doped alloys are utilized for making cores of small transformers, contactless relays, pulsing transformers, intensifiers, and screens. Permalloys with 65−68% content of nickel that provide a rectangular hysteresis loop, have got a practical significance in some types of computing tools, automation devices.
