FeCrCo permanent magnet first appeared in the early 1970s. It is an age-hardening deformable permanent magnet with a wide range of alloy composition. Its basic composition is 20~33% Cr, 3~25% Co, and the rest is Fe. In this article, let’s take a quick look at the FeCrCo Magnet.
The magnetic properties of FeCrCo magnets are equivalent to that of AlNiCo magnets. The FeCrCo magnets can be magnetized with multiple poles in a plane, and at the same time have the advantage of being machined, especially suitable for making a thin permanent magnet with small size and complex shape, which are often used in telephones, tachometer, micro-motor, micro-relay, loudspeaker, etc.
The Performance of FeCrCo Magnets
The Curie temperature of FeCrCo permanent magnets is high (Tc=680℃), the service temperature can reach 400℃, the reversible temperature coefficient is small, and the magnetic performance stability is good at high temperatures. Therefore, they are suitable for high-precision components that require high stability.
FeCrCo permanent magnets are known as transformers in permanent magnets. They are easy to metal processing, especially wire drawing and tube drawing. This is an advantage that other permanent magnets cannot compare with.
FeCrCo alloy can be made into bars, strips, wires, and pipes through cold thermoplastic deformation, and can also be cold punched, bent, drilled and various cutting processes to make various complex magnet components. The minimum wire diameter can be as high as 0.05mm, and the thickness of the thinnest strip is only 0.1mm.
