Precision alloy 49KF relates to soft-magnetic alloys. It has a high magnetostriction, an excellent magnetic saturation not less than 2.35 T, and a high Curie-point 950 °C. Soft-magnetic materials possess a great index of primary magnetical inductive capacity; they can magnetize themselves in weak fields up to saturation. The alloys, in which composition there are cobalt and vanadium (except for iron) relate to this group.

Welding

Type Description
limited welded welding is possible at heating to 100−120°С and last heat treating
hardly welded in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, heat treating (annealing) after welding
welded without stint welding is done without further heat treating or previous heating

Appliaction

Soft-magnetic alloys of a grade 49KF are used in cores, pole pieces, magnets and solenoids. It is utilized in electric machine industry, transformers and radio engineering, an electrotechnical sphere of industry and in automation systems, teleautomatics, computationally measuring equipment. An extra pure ferromagnet iron, low-carbon electrothecnical steels (siliceous, unalloyed), low-coercive precision alloys on an iron-nickel or iron basis relate to this category of soft-magnetic alloys. They can also be ferromagnet, ferrimagnet, powdered, compositional. Precision alloys are used in spheres of accurate instrument engineering. It is also popular at manufacturing electronic units, household appliances, details of laser techniques and metrologic and measuring equipment. Soft-magnetic alloys are melted in special furnaces for obtaining required shapes. After that, they can be exposed to rolling or forging. Soft-magnetic alloys are extensively used in modern industry. They are used for manufacturing transformers, microphone cores, components of computer storage, magnetic antennas, details of electric machines and magnet cores that are intended to work in sea water.
