Ni80Mo5 Finemet Magnetic Alloy Strip 1j85 Permalloy With ISO 9001 Standard
1j85 Soft Magnetic Alloys 1J85 / FeNi 85 / Ni80Mo5 FINEMET magnetic alloy strip 1j85 Permalloy
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.
Permalloy magnetic shielding to do: In order to prevent interference of external magnetic field, often in CRT, an external CRT electron beam focusing section plus the magnetic shield, you can play the role of magnetic shielding.
