Buy Permendur 49KF wire from Evek GmbH

Permendur-2v (or HiperCo 50A - according to foreign classification) is a magnetically soft alloy, which composition and properties are regulated by GOST 10994. It is used in electrical equipment which operates in conditions of high magnetic flux density.

Composition and characteristics

The main components of the alloy are chemically pure iron (47...50%) and cobalt (48...49%). The rest is vanadium (not more than 1.9%) and impurities - silicon and manganese. Permendur-2v is produced by vacuum-arc smelting.

The main characteristic of the alloy is its high magnetostriction - the ability to change dimensions with the change of magnetic flux intensity. That's why it is profitable to produce such parts of magnetic systems as coils, poles of lugs and cores of powerful magnets.

The use of 49KF

Difficult machinability. Machining is carried out at reduced rotational speed and feed rate of the working tool, and the punching of the perimeter is performed only in hot condition; the hardness decreases from 94HRB (t ° 843 °C), to 82HRB at 925 °C. Above this temperature the alloy loses its magnetic properties;

Heat treating regimes.

Heat treatment is carried out at temperatures of 885 ± 15 ° C in furnaces with an oxid-free atmosphere and in the absence of carbonization. Cooling after heating is carried out in the furnace, to 370 ° C, and after - in the open air.

Conditions of Production and Delivery

The predominant production range of alloy 49KF by other manufacturers - hot-rolled bars with a diameter of 12 mm. Evek GmbH offers:

Supply of permendur-2v in the form of drawn wire;

Improved homogeneity of microstructure and alloy properties;

Prompt order fulfillment regardless of its volume.

49KF permendur wire is produced in the following size nomenclature, mm: 1,6; 1,7; 1,8; 2,05; 2,15; 2,20. Steel wire with diameter up to 5 mm with the limiting deviation js10 and js11 (GOST 2771) may be delivered by special order.

The price for 49KF wire from Evek GmbH is affordable and profitable for the consumers. For a decent price they will get guaranteed quality products that can be used in the manufacture of small electric motors, measuring equipment and other devices that require the maximum value of magnetic induction and minimum power loss caused by eddy currents.
