Description

Fe-Ni based soft magnetic alloys (1J46, 1J50, 1J54) offer balanced high saturation induction and high permeability. Ideal for transformers, relays, motors, and magnetic circuits. GBn 198-88 compliant.

1J46, 1J50 and 1J54 High Permeability Soft Magnetic Alloys

1J46, 1J50 and 1J54 are Fe-Ni soft magnetic alloys developed for applications requiring a combination of high magnetic permeability and relatively high saturation magnetic induction.

These alloys are used in magnetic circuits operating at moderate magnetic fields, including transformer cores, relay components, electromagnetic clutches, chokes, magnetic cores and other precision electromagnetic components.

Greenergy Materials supplies 1J46, 1J50 and 1J54 soft magnetic alloys in customized material forms and dimensions according to application requirements, material specifications and production needs.

What Are 1J46, 1J50 and 1J54 Soft Magnetic Alloys?

1J46, 1J50 and 1J54 belong to the Fe-Ni family of soft magnetic alloys with high permeability and higher saturation magnetic induction.

Compared with conventional soft magnetic materials designed primarily for general electromagnetic applications, these alloys provide a useful balance between:

• Magnetic permeability

• Saturation magnetic induction

• Coercive force

• Magnetic response

• Electrical resistivity

• Processability

They are particularly useful when a magnetic component needs both good permeability and sufficient magnetic flux capacity.

Key Properties of 1J46, 1J50 and 1J54

High Magnetic Permeability

High permeability allows a magnetic material to respond effectively to a relatively small magnetizing field.

This makes 1J46, 1J50 and 1J54 suitable for magnetic circuits where efficient flux conduction is required.

Typical applications include:

• Transformer cores

• Relay cores

• Electromagnetic components

• Magnetic shielding components

• Chokes

• Magnetic circuit parts

Higher Saturation Magnetic Induction

One of the defining characteristics of this alloy family is its relatively high saturation magnetic induction compared with many high-permeability Fe-Ni alloys.

This provides a useful balance between permeability and magnetic flux capacity.

The published material classification identifies 1J46, 1J50 and 1J54 as soft magnetic alloys with high permeability and higher saturation magnetic induction.

Low Coercive Force

Low coercive force is important for soft magnetic applications because it allows the material to magnetize and demagnetize more easily.

Actual coercive force depends on alloy grade, product form, thickness, heat treatment and test conditions.

Stable Magnetic Performance

For industrial magnetic components, consistent material properties are important for maintaining repeatable component performance.

Material processing and final heat treatment should therefore be controlled according to the applicable material specification.

1J46 vs 1J50 vs 1J54

Although all three grades belong to the same high-permeability and higher-saturation-induction family, their compositions and magnetic characteristics are not identical.

The appropriate grade should be selected according to the required magnetic properties, operating field, product form, heat treatment and application.

Chemical Composition of 1J46, 1J50 and 1J54

Typical standard-based composition ranges are summarized below.

*The exact Si range should be confirmed against the applicable current material standard and the production specification used for your order.

The published standard-related data confirms the distinct Ni and Cr composition ranges of these three grades.

Magnetic Properties of 1J46 and 1J50

Magnetic properties should always be evaluated according to the product form, thickness, test method and heat-treatment condition.

For example, published technical data for 1J46 shows different permeability and coercive-force requirements at different strip thicknesses, while 1J50 data likewise varies with thickness and frequency.

A typical technical data table for production should therefore include:

For quotation and production, Greenergy Materials can provide the applicable technical data according to the selected grade and product specification.

Why Choose a High Permeability and Higher Saturation Alloy?

Magnetic material selection is usually a trade-off between different properties.

A material with extremely high permeability may not always provide the required saturation magnetic induction.

Conversely, a material with extremely high saturation induction may not provide the permeability required by a low-field magnetic circuit.

1J46, 1J50 and 1J54 are designed for applications where engineers need a practical balance between these properties.

They can therefore be considered when the magnetic circuit requires:

• Good magnetic permeability

• Relatively high saturation induction

• Low coercive force

• Stable magnetic response

• Suitable mechanical processing characteristics

Applications of 1J46, 1J50 and 1J54

Transformer Cores

1J46, 1J50 and 1J54 can be used in selected transformer core applications where high permeability and adequate saturation magnetic induction are required.

Motors and Electromagnetic Devices

Certain 1J-series Fe-Ni alloys are used in magnetic components of motors and other electromagnetic devices where the balance between permeability and saturation induction is important.

1J46 vs 1J50 vs 1J54: How to Choose?

The correct grade should not be selected only by the alloy number.

Choose 1J46 When

Consider 1J46 when your application requires the magnetic characteristics associated with its approximately 45–46.5% nickel composition and high-permeability / higher-saturation material class.

Choose 1J50 When

1J50 is a common choice when the application requires approximately 49–50.5% nickel Fe-Ni soft magnetic material with a combination of permeability and higher saturation induction.

Choose 1J54 When

1J54 should be considered when the application requires the specific magnetic and compositional characteristics of its Ni-Cr-containing Fe-Ni alloy system.

For final selection, compare the required magnetic properties with the actual material datasheet.

1J50 Soft Magnetic Alloy for Medium Magnetic Fields

1J46, 1J50 and 1J54 are commonly considered for magnetic circuits operating in moderate magnetic fields.

This differentiates them from several other soft magnetic alloy families on the market.

For example:

• 1J22 is selected primarily for very high saturation induction.

• 1J76 / 1J79 / 1J85 are selected for high initial or maximum permeability.

• 1J34 / 1J51 are selected for rectangular hysteresis characteristics.

• 1J30 / 1J31 / 1J32 / 1J33 / 1J38 are used for magnetic temperature compensation.

• 1J46 / 1J50 / 1J54 provide a balance between permeability and higher saturation magnetic induction.

This distinction is important when selecting a material for a specific magnetic circuit.

Comparison with 1J22 High Saturation Induction Alloy

If your main requirement is maximum saturation induction, 1J22 may be more appropriate.

If the application requires a balance between permeability and saturation induction, 1J46, 1J50 or 1J54 may be more suitable.

Comparison with High Initial Permeability Alloys

High initial permeability alloys such as other Fe-Ni grades are designed primarily for strong magnetic response under weak magnetic fields.

1J46, 1J50 and 1J54 are instead positioned in the material family combining high permeability with higher saturation magnetic induction.

Therefore, the best material depends on whether the application prioritizes:

• Initial permeability

• Maximum permeability

• Saturation induction

• Coercive force

• Frequency

• Magnetic loss

• Operating field
