Overview


Alloy 50 is a Ni-Fe soft magnetic alloy, and its main compositions are about 50% Ni, 48% Fe and other micro-elements. This alloy is characterized by high magnetic permeability, higher saturation induction density, etc. As a soft magnetic material used in alternating current, vortex and loss are induced inside the material due to the alternating magnetization. The smaller the resistivity and the greater the thickness of the alloy, and the higher frequency under the alternating magnetic field, the greater the eddy loss and the more the decrease of the magnetic performance.


The processing performance of alloy 50 is good, and it can be made into various components with complex shapes and precise dimensions, such as sheet and bar. Because of its high permeability and low coercivity characteristics, it has been widely used in transformer, magnetic shield, magnetic head, aerospace precision control instrument and other fields. In addition, it can also be used as pulse transformers and inductance cores with low remanence and constant permeability, as well as high rectangular ratio alloys, thermal magnetic compensation alloys and magnetostrictive alloys.

Heat treatment


In-Process Annealing: To remove all strain and restore the alloy to a soft state suitable for further cold rolling or drawing, forming, bending or similar operations, anneal at 1020-1080°C for no more than 1 hour. In-process annealing should be performed in dissociated ammonia, hydrogen, vacuum or inert gas

atmosphere.

Final Annealing: For maximum softness and the best magnetoelectric properties, cold deformed 1J50 alloy should be annealed in an oxygen-free, dry hydrogen atmosphere at 1180°C with a dew point below -40°C for 3-5 hours.

Oil, grease, paint and all other contaminants must be removed prior to annealing. During hydrogen annealing, individual parts should be separated by inert insulating powders such as magnesia and alumina.

Vacuum heat treatment can be used, but it usually results in a sacrifice of magnetic properties compared to heat treatment in a dry hydrogen atmosphere.
