Iron chromium cobalt (FeCrCo) magnet rings are a type of high-performance magnetic material that is widely used in various industrial applications due to their excellent magnetic properties, such as high magnetic flux density and coercivity. These magnetic rings are often used in miniature torque meters, which are devices designed to measure the rotational force, or torque, applied to a rotating shaft or component.
Ring ferrochrome cobalt magnet with OD 14mm and height 7.9mm
The FeCrCo magnet ring serves as a key component in the torque meter, generating a magnetic field that is proportional to the applied torque and allowing for accurate and reliable torque measurements. In this way, the FeCrCo magnet ring plays a crucial role in the functioning of miniature torque meters, which are used in a variety of fields, including automotive, aerospace, and robotics.
Basic characteristics of FeCrCo magnets:
Curie temperature is high (Tc=680℃ or so), the use temperature can reach 400℃. Reversible temperature coefficient is small, good magnetic stability at high temperature, suitable for high stability requirements of high precision components.
Density: 7.7-7.8g/cm3.
Performance is not high, remanence Br=13000-14000 Gaz, coercivity Hc=650KOe about 52KA/M, (BH)max=6.0MGOe.
Not easy to break, not easy to crack, very malleable and plasticity, suitable for the production of complex shape small size or large thin permanent magnet element;
It can be made into wire, strip, bar and pipe by cold thermoplastic deformation, and can also be processed into micro, light, thin and complex shape components by stamping, bending, punching and cutting. The amount of cobalt in the ferrochrome-cobalt magnet can not only control the intrinsic coercivity, but also affect the machining performance of the material.
