Hy-Mu 80(Ni-Cr-Mo)

1. Introduce

– Permalloy

– Alloy with soft magnetic, magnetic shielding properties

– UNS N14080

* Permalloy

1. typically an alloy with 35 to 80% Ni and 20% Fe
2. alloys with the characteristics of very high permeability and low magnetic hysteresis losses

* Soft magnetic materials : High permeability materials with the characteristics of high permeability, low coercivity and low hysteresis losses
→ Permeability : A measure of how much magnetization occurs when an external magnetic field is applied
→ Coercivity : the strength of an external magnetic field required to zero out the magnetization of a ferromagnet
→ Hysteresis : A phenomenon in which a certain amount of magnetization remains when an external magnetic field is removed without returning to the original state
→ High permeability materials : magnetic materials that are easily magnetized even with weak magnetic fields

* Magnetic shielding : Reducing the magnetic field in space by blocking the magnetic field with a barrier made of conductive or magnetic materials

* UNS

1. Abbreviation for Unified Numbering Systems for Metals and Alloys
2. Unified Numbering Systems for Metals and Alloys
3. A representative number that is compatible with metals and alloys defined in many material-related codes such as ASTM, AISI, ASME, AWS, etc.

* N : Nickel and nickel alloys

* UNS N14080 : 14XXX : Iron

2. Property

– Soft magnetic, magnetic shielding properties

– Excellent machinability
→ Lower wear resistance than hard magnetic materials as a soft material
