Rod, pipe 50NHS are widely used in a modern industry at manufacturing transformer cores, microphones, components of computer memory, magnetic antennas, details for electric machines, magnet cores which are intended to be exploited in sea water.

Technical characteristics

Extra-pure ferromagnet iron, siliceous low-coercive precision alloys on a iron-nickel or iron basis that alloyed with silicon and magnet relate to this soft-magnetic alloys. Ferromagnet, ferrimagnet, powdered and compositional materials also belong to this category. Possessing a high magnitude of initial permeability, soft-magnetic materials can magnetize to saturation on weak fields. Such alloys are melted in special metallurgical furnaces for obtaining required shapes, exposing their ingots to malleating and rolling in future. They are utilized in electric machine industry, transformer, radio engineering, magnet cores of a variable magnetic field, an electrotechnical sphere of industry, automation systems, teleautomatics and computationally measuring equipment.

Iron-nickel alloys are smelted in an open arc furnace. They possess 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 the electromagnetic properties. A smelt is done in a vacuum or inert gas environment. Semi-fabricates of minimal thickness are manufactured with a method of cold-rolled stamping with further annealing. It is done for increasing magnetic properties. Permalloy of this grade has improved features and an increased magnetizing. This alloy is characterized by a significant magnetic sensitivity in relation to external changes.
