NiFe50 permalloy pipe
Alloys on iron basis, alloyed with nickel, mangan, copper, cobalt relate to soft-magnetic alloys. Extra-pure ferromagnet iron or low-carbon electrotechnical steels (unalloyed, siliceous) also relate to this category. They are precision low-coercive alloys with iron-nickel basis. Such alloys are smelted in special metallurgic furnaces. Prepared ingots are exposed to further forging and cogging. Soft-magnetic alloys have an increased induction of technical saturation and raised magnetic inductive capacity. They are utilized in manufacture of transformers and magnetic cores of variable magnetic field. They are also used in radio engineering, an electrotechnical sphere of industry and in automation systems, teleautomatics, computationally measuring equipment.
Permalloy is used in manufacturing cores of small-sized and high-power transformers, relay actuators, chokes and details of magnetic circuits that are exploited while working at increased induction with a small bias or without it. Possessing a high magnitude of initial permeability, soft-magnetic alloy NiFe50 is capable of magnetizing to saturation on weak fields.

Permalloy is smelted in open arc furnace. A usage of special masteralloys gives a material the most precious properties (elastic, magnet, heating, electrical). This steel possesses balanced technological characteristics due to which it is so popular. Tubes of NiFe50 grade are used in spheres of precision machine tool building, an accurate instrument engineering, innovative technologies.
Mechanical properties at a temperature 20 °C
By virtue of unique physical and mechanical properties, permalloy is widely used in a modern industry. Unique properties of a material are conditioned by its balanced composition. With an appearance of a materials of a new generation, there has become a possibility to improve many technological processes and to provide a long-term and reliable work of equipment in a wide temperature range.
