Soft Magnetic Alloys

Soft magnetic alloys are nickel based alloys that are applied in many applications, mostly in the Electronics field. Main usage is shielding against magnetic interference, and inductive power generation.

PHYNICX 36 – FeNi36

This 36 % nickel-iron alloy has the lowest nickel percentage of the three main soft magnetic alloys.

Typical functions in technologies

magnetic shielding, induction and magnetic field generation, core material transformers, stator and rotor material

Typical industries that apply FeNi 36 material in their technology because of magnetic properties

watch industry, electronics and electric power generation.

PHYNICX 48 – FeNi48

This nickel-iron alloy has a typically high saturation level, together with high permeability. Excellent combination to shield in miniaturized products as watches, ear-aiding equipment and mobile telephones.

Typical functions in technologies

magnetic shielding, induction and magnetic field generation, core material transformers, chokes and sensors.

Typical industries that apply FeNi 50 material in their technology because of magnetic properties

watch industry, electronics, electric power generation, measuring industry and military.

PHYNICX 80 – FeNi 80

This high % nickel-iron alloy has a typically very high permeability. Excellent properties to shield larger magnetic fields. This material however has a relatively low saturation level.

Typical functions in technologies

magnetic shielding, induction and magnetic field generation and core material transformers, chokes and sensors.

Typical industries that apply FeNi 80 material in their technology because of magnetic properties

watch industry, electronics and electric power generation.

PHYNICX 4949 – Co49Fe49V2

Cobalt-iron alloys have the highest saturation polarization of all known magnetic alloys This about 50 % cobalt-iron alloy is the most common of Co-Fe alloys.

PHYNICX 3030-3090

Dependent on the % of nickel used, and a specific final heat treatment, the curie temperature of nickel alloys can be defined. When alloys are heated, they will start loosing their inherent magnetic properties. The temperature, at which there is no magnetic property, is called the Curie temperature. This alloy is mainly used in safety devices.
