Tape, round, wire 50NKHS
Magnetically soft precision alloy brand 50NKHS used in the manufacture of communications equipment audio and high frequencies, and the cores of pulse transformers, operating without bias. Having a high value of initial magnetic permeability, soft magnetic materials can be magnetized in weak fields, and also to saturation. To soft magnetic alloys are alloys whose composition includes cobalt, Nickel in addition to iron. Applied soft magnetic alloy 27KKH, typically in electrical engineering, in the production of magnetic alternating magnetic field in the transformer industry, radio engineering, electrical engineering, systems automation, remote control, computer measurement technology. To the class of magnetically soft materials is a particularly pure ferromagnetic iron, electrical low carbon steel (non-alloy, silica), precision nizkotemperaturnye alloys with iron-Nickel, iron base, ferrimagnetic and ferromagnetic powder, composite. Such alloys are melted in a special metallurgical furnaces for production of necessary forms, exposing them to the bars later forging or rolling. Soft magnetic alloys are widely used in modern industry in the manufacture of transformer cores, microphones, components, memory for computers, magnetic cores which are designed for operation in sea water, parts for electric machines, magnetic antennas.
The hardness of the alloy 50NKHS is HB 10 -1 = 125 — 190 MPa.
| Welding: | |
|---|---|
| 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. |
