Soft-magnetic alloy of an actual grade is usually used in cores of small-sized and high-power transformers, relay actuators, chokes, details of magnetic circuits. They operate at increased induction with a small bias or without it. Alloy is utilized in electric machine industry, transformer and radio engineering, an electrotechnical sphere of industry, in automation systems, teleautomatics, computationally measuring equipment.

Technical characteristics

Extra pure ferromagnetic iron, low-carbon electrotechnical steel (siliceous, unalloyed), low-coercive precision alloys on a ferromagnetic basis also relate to this type of soft-magnetic alloys. They are melted in special metallurgic furnaces for obtaining required shapes. After that, they can be exposed to rolling or forging. Such alloys are essential in modern innovative technologies, spheres of accurate instrument engineering. They are also popular at manufacturing the electronic units, household appliances, details of laser techniques and metrologic-measuring equipment.


«Auremo» company delivers precision alloys on the favorable terms. There is a wide range of goods of a high quality in stock. If you buy products by wholesale, you will be given special discounts. An availability of products and efficiency of delivery are conditioned by a fact that we have offices in Moscow, St. Petersburg and cities of Central Europe.

Alloy of this grade is a soft-magnetic and has an increased magnetic inductive capacity and saturation induction. According to GOST 19 693−74, this material has a coercive force by induction that does not exceed 4 kA/m.


Type Description
limitedly weldable a weld is possible after heating to a temperature 100−120 °C and further heat treating
hardly weldable 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.
weldable without stint welding is done without further heat treating or previous heating.
