Tape, round, wire 45N - alloy 45

Tape, round, wire 45N - alloy 45

The alloy grade 45N is magnetically soft and has a high magnetic permeability and higher induction of technical saturation. This magnetic material having a coercive force by induction according to GOST 19693−74not to exceed 4 kA/m.

Soft magnetic alloys have high initial magnetic permeability. These alloys are magnetized to saturation in weak fields. Such alloys are alloys, which contains iron in addition to cobalt and Nickel. Soft magnetic alloy brand 45N, usually used in cores of small-sized and magdalinova power transformers, relays, chokes and parts of magnetic circuits that operate at higher operating induction with a small bias or without bias. It is used in electrical engineering, transformer industry, electronic, electrical industries and in the systems of automation, remote control, computer measurement technology. This type of soft magnetic materials include ferromagnetic ultra-pure iron, mild steel electrical (siliceous, undoped), precision alloy nizkotemperaturnye on iron-Nickel, iron base, ferrimagnetic, ferromagnetic, powder composites. Precision alloys are used in the fields of precision machine tools in the manufacture of precise electronic equipment and household appliances, laser technology in innovative technologies, products Metrology and measurement equipment. The alloys are magnetically soft melted in a special metallurgical furnaces to produce the required shapes, and thereafter, the alloy ingots are rolled or forging. Alloys soft magnetic find in the modern industry wide application. They are used for transformers in the manufacture of cores used in microphones, in the manufacture of components of the computer memory as well as magnetic cores, which are designed for operation in sea water, as well as magnetic antennas, parts, electric machines, etc.

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.
