FeCrCo Permanent Magnet Alloy | Wrought Iron-Chromium-Cobalt Magnets


Product Overview

FeCrCo permanent magnet alloy is a rare-earth-free permanent magnetic material based on iron, chromium and cobalt. It combines permanent magnetic performance with excellent ductility, machinability, formability and high-temperature stability, making it suitable for producing thin, small and complex-shaped magnetic components.

Unlike many brittle permanent magnet materials, wrought Fe-Cr-Co permanent magnet alloy can be processed through rolling, drawing, stamping, bending and machining before final magnetic heat treatment. This makes FeCrCo particularly useful when a permanent magnet requires precise dimensions, narrow sections, wires, strips or complicated geometries.

Hefei Ke Ningman New Energy Materials Technology Co., Ltd. supplies wrought FeCrCo permanent magnet alloys in customized forms and dimensions according to customer drawings, magnetic requirements and application conditions. Available product forms can include strip, sheet, wire, rod, bar and other customized shapes.

What Is FeCrCo Permanent Magnet Alloy?

FeCrCo is an iron-chromium-cobalt permanent magnet alloy developed for applications that require a combination of magnetic performance and mechanical workability.

The alloy can be manufactured as a wrought permanent magnet material, allowing it to undergo conventional metalworking processes before its final magnetic heat treatment. This characteristic distinguishes FeCrCo from many conventional permanent magnet materials that are difficult to form or machine after magnetization.

The magnetic properties of FeCrCo are developed through carefully controlled heat treatment and magnetic aging. Its microstructure and processing history have a significant influence on the final remanence, coercivity and maximum energy product.

For this reason, FeCrCo is particularly suitable for precision components where both magnetic performance and manufacturing flexibility are important.

Why Choose FeCrCo Permanent Magnets?

Excellent Machinability

One of the most important advantages of FeCrCo is its excellent mechanical workability before final magnetic aging.

Depending on the required product geometry, FeCrCo can be processed using methods such as:

  • Cutting

  • Turning

  • Drilling

  • Milling

  • Stamping

  • Rolling

  • Drawing

  • Bending

  • Forming

This provides greater manufacturing flexibility when producing precision magnetic components.

High Ductility and Formability

FeCrCo offers significantly better ductility and formability than many brittle permanent magnet materials.

It can be processed into thin strips, wires, narrow sections and other geometries that may be difficult to manufacture from conventional hard magnetic materials.

This makes FeCrCo an excellent option for applications requiring:

  • Thin magnetic components

  • Small magnetic parts

  • Long and narrow magnets

  • Curved components

  • Complex profiles

  • Customized magnetic structures

High Curie Temperature

FeCrCo alloys have a relatively high Curie temperature compared with many permanent magnet materials.

The exact Curie temperature and recommended operating temperature depend on the alloy grade and heat treatment. For high-temperature applications, the appropriate grade should be selected according to the actual operating environment.

Good Resistance to Demagnetization

Properly heat-treated FeCrCo can provide strong resistance to demagnetization and stable permanent magnetic performance.

This is particularly important in magnetic components exposed to elevated temperatures or external magnetic fields.

Complex Shape Capability

FeCrCo is especially attractive when the final magnet needs a geometry that cannot be easily produced using conventional brittle permanent magnet materials.

Its combination of ductility, machinability and magnetic properties allows manufacturers to produce customized shapes with controlled dimensions and tolerances.


FeCrCo Permanent Magnet Manufacturing Process

The manufacturing process is carefully controlled because both mechanical properties and magnetic performance depend on composition, deformation and heat treatment.

1. Raw Material Preparation

Iron, chromium, cobalt and other required alloying elements are prepared according to the selected material specification.

2. Melting and Alloy Formation

The raw materials are melted under controlled conditions to achieve the required chemical composition and material uniformity.

3. Casting and Homogenization

The alloy is cast and may undergo homogenization treatment to improve compositional uniformity before subsequent processing.

4. Hot Working

The material can be hot rolled, forged or otherwise hot worked into an appropriate intermediate form.

5. Cold Rolling or Drawing

Cold working can be used to achieve the required thickness, diameter, dimensional accuracy and surface condition.

Typical products include:

  • FeCrCo strip

  • FeCrCo sheet

  • FeCrCo wire

  • FeCrCo rod

  • FeCrCo bar

6. Precision Machining

Depending on the product design, FeCrCo can be machined or formed into the required geometry before final magnetic treatment.

7. Magnetic Heat Treatment

Controlled heat treatment and magnetic aging are used to develop the desired magnetic microstructure and permanent magnetic properties.

8. Magnetization

The finished component can be magnetized according to the required magnetic direction and application.

9. Final Inspection

Final inspection may include dimensional inspection, surface inspection, chemical composition verification and magnetic property testing according to the agreed specification.


FeCrCo Magnetic Properties

The magnetic performance of FeCrCo depends strongly on alloy composition, deformation, heat treatment and magnetic aging.
