Product Description
Soft magnetic alloys Permalloy / 1J79 / 79HM
Soft magnetic alloys mainly used in two areas for energy conversion and information processing.
In the power industry, mainly in the high magnetic field has a high magnetic induction and low core loss of the alloy. In the electronics industry, mainly at low or medium alloy having a high magnetic permeability and low coercive force. At high frequencies shall be made on a thin strip or alloy higher resistivity. Usually with sheet or strip.
Be use in exchange , due to the alternating magnetic eddy currents are induced inside the material, resulting in the loss, the smaller the resistance of the alloy, the greater the thickness, the higher the frequency of the alternating magnetic field, eddy current losses greater, magnetic reduce more. For this, the material must be made thinner sheet (tape), and the surface coated with an insulating layer, or the use of certain methods to the surface to form an oxide insulating layer, such alloys commonly used magnesium oxide electrophoresis coating.
In order to prevent interference of external magnetic fields, often in the oscilloscope tube, the picture tube electron beam focusing section plus the external magnetic shield, the magnetic shield can play a role.
The following is the data permalloy:
