FeCrCo Magnets
Iron Chrome Cobalt FeCrCo Magnets
Overview
Iron-Chrome-Cobalt magnets (FeCrCo) have similar properties to cast
Alnico 5 but, unlike cast alnico, the FeCrCo magnets are actually
reasonably malleable.
The FeCrCo magnet material is semi-hard magnetically and exists in
bar, rod, wire and also as thin rolled strip.
They are a replacement for CuNiFe magnetic material (CuNiFe is not
commercially available any more).

Advantages
• Malleable – FeCrCo is easier to machine than Alnico
• FeCrCo can be hot deformed
• The maximum recommended operating temperature is typically around
+400 degrees C (752F)
• FeCrCo has a Hc varying typically from 50kA/m to 300kA/m. The
value of Hc produced depends on the method of the final heat
treatment (timescale, temperature and quench rate)
• FeCrCo usually does not require any corrosion coating
Disadvantages
• If the final heat treatment is not performed, the magnetic
performance is very poor
• The strips are usually thin. Thicker sheets and plate are not
really possible
• Easily demagnetised or remagnetised in a different direction
Typical Applications
• Compasses
• Hysteresis coupling applications e.g. a multi-pole permanent
magnet rotor turning a FeCrCo disc by hysteresis
Example
A company wanted a customised needle for a compass they were
designing.
The needle could be produced to the shape, heat treated, painted
and magnetised to their requirements.
Iron chromium Cobalt (FeCrCo) magnets are similar to Alnico magnets in magnetic property, but they have
better mechanical property. FeCrCo alloys can be easily hot
deformed and machined. There are practically no limitations of
their shapes and sizes. They can be made to block, square rods,
round rods, tube, strips, wire. FeCrCo magnets are beneficial
combination of magnets and mechanical properties. Their maximum
working trmperature can be as high as 400°C.
FeCrCo Characteristics:
FeCrCo Can be made to small and complex shape components. Its
minimum diameter can reach 0.05mm and the thinnest thickness can
reach 0.1mm, so it is suitable for the production of high-precision
components. It has good temperature stability and corrosion
resistance. The high Curie temperature is about 680℃ and the
highest wroking teperature can reach 400℃ .
Iron-Chrome-Cobalt permanent magnets are a malleable, magnetically
semi-hard alloy which is available in cast form (see the Alnico
Magnet section) and as thin rolled strip,bar,rod or wire from
Rolled Products facility. It is an excellent material for
hysteresis coupling and for sensor applications. It is also a
substitute for CuNiFe, which is no longer commercially available.

Packing:
As the magnets have strong attraction and we will use the spacer to
apart the magnets each other in case people will be hurt when take
it out. Then, they will be packed in a white box of pieces each,
several boxes to a carton.
+By Air: If the goods will be shipped by air, all the magnetic
should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a
pallet on the bottom of cartons.
Shipping:
Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in
shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or
Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.
