The material of magnetically soft type 50NP differs by a significant indicator of magnetic permeability and a sufficiently high value of saturation induction. Due to this feature, even under the action of a low-strength magnetic field, the material rapidly magnetizes, which determines the main sphere of its application in industry. It is important to note that the important performance characteristics of such semi-finished products are regulated by the state standard 19693−74, and the coercive force of the raw material is low (no more than 4 kA / m).


Due to its unique properties, a precision alloy with a similar labeling is actively used for the needs of the power complex, radio engineering, manufacturing of automated systems and television equipment. Also, without such material, the manufacture of measuring devices or computer parts is not complete. Another area of use of semi-finished products from such raw materials is the production of transformer technology, or more precisely, the cores of power devices of interlamp and small-sized type, various relay devices and chokes.

Features of welding

The alloy has limitations on weldability The welding process requires some preliminary preparation (warming the contacting surfaces to one hundred and one hundred and twenty degrees and subsequent heat treatment of the seam zone)
The alloy has no weld constraints No additional operations are required
Hard to weld material It is necessary to warm the contacting surfaces to two hundred or three hundred degrees, the subsequent annealing and heat treatment after the end of the welding process

Buy at the best price

Acceptable cost of brand 50NP and a wide range of products against the backdrop of a wide variety of parameters of semi-finished products will allow any buyer to choose the product that will most fully satisfy all of his individual needs. High quality of manufacturing and full conformity of production to requirements of the state standard documentation and technical conditions for delivery — that basic criterion which our company adheres in work with clients. Precisely calibrated chemical composition and manufacturing ensure the reliability of the product and the exact correspondence of its performance to the claimed qualities, while reasonable prices and a convenient method of delivery is an additional advantage in working with us.
