Tape, round, wire 50NP - alloy 50

Tape, round, wire 50NP - alloy 50

General characteristics

To soft magnetic alloys are alloys based on iron, alloyed with Nickel and cobalt. Their composition is a particularly pure ferromagnetic iron or low carbon electrical steel (non-alloy, silicon). It nizkotemperaturnye precision alloys with high Nickel based ferrimagnetic and ferromagnetic powder, composite. Such alloys are melted in a special metallurgical furnaces. Ready bullion subsequently subjected to forging or rolling. Magnetically soft alloy has a high technical saturation induction, high magnetic permeability. Used in the manufacture of transformers, magnetic AC magnetic field, electronic and electrical parts, systems automation, remote control, computer measurement technology.


Alloy 50NP used in the manufacture of small cores, magdalinova power transformers, chokes, parts of magnetic circuits, a relay operated with a small magnetization, or without it at high inductions. Having a high value of initial magnetic permeability soft magnetic alloy 50NP can be magnetized to saturation in weak fields.

weldability limited — welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment
konovalivka in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding.
Welded without any restrictions — welding is carried out without further heat treatment and pre-heating.
