铁钴合金是指含有钴的铁，较不常见，结合成矿物的形式共存，用于生产磁性合

Iron-cobalt alloy refers to iron containing cobalt, which is less common and coexists in the form of combined minerals, and is used to produce magnetic alloys and anti-abrasion and high-temperature hard alloys. Iron-cobalt alloy soft magnetic material containing about 50% cobalt. In order to improve processing performance, 1.4~1.8% of vanadium (V) is usually added, so it is also called Fe-Co-V soft magnetic alloy. It has a very high saturation magnetic flux density Bs (2.4T) and Curie temperature (980~1100℃), so it is suitable for the production of aviation electrical appliances (micromotors, electromagnets, Relay, etc.). It also has a large saturation magnetostrictive coefficient λs, which can be used to make magnetostrictive transducers.

Iron cobalt alloy refers to iron containing cobalt, which is less common and coexists in the form of synthetic minerals. It is used to produce magnetic alloy and cemented carbide with abrasion resistance and high temperature resistance. Iron cobalt alloy containing about 50% cobalt is a soft magnetic material. In order to improve the processability, 1.4 ~ 1.8% vanadium (V) is usually added, so it is also called iron cobalt vanadium soft magnetic alloy. It has extremely high saturation flux density BS (2.4t) and Curie temperature (980 ~ 1100 ℃), so it is suitable for making aviation electrical appliances (micro special motors, electromagnets, relays, etc.) requiring light weight, small volume and high working temperature. It also has a large saturation magnetostrictive coefficient λ s. It can be used to make magnetostrictive transducer.
