铁钴是指含有钴的铁，较不常见，结合成矿物的形式共存，用于生产磁性合金和

Iron-cobalt 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 hard alloys that are resistant to abrasion and high temperature. Cobalt itself is a hard and silver-white divalent and trivalent metal element. It is magnetic and belongs to the same family as iron and nickel. It is usually in the form of nickel or copper or in natural nickel-iron alloys (such as meteorites). 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 refers to iron containing cobalt, which is less common and coexists in the form of synthetic minerals. It is used to produce magnetic alloys and cemented carbides resistant to abrasion and high temperature. Cobalt itself is a hard and silvery white divalent and trivalent metal element with magnetism. It belongs to the same family as iron and nickel. It is usually in the form of nickel or copper or natural ferronickel alloy (such as meteorite). Ferrocobalt alloy containing about 50% cobalt is a soft magnetic material. In order to improve processing performance, 1.4 ~ 1.8% vanadium (V) is usually added, so it is also called ferrocobalt 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.

Cobalt itself is a hard silver-white divalent and trivalent metallic element with magnetism, belonging to the same family as iron and nickel, usually with nickel or copper or in the form of natural nickel-iron alloy (such as meteorite). Fe-Co alloy soft magnetic materials containing about 50% cobalt. In order to improve the processability, 1.4~1.8% vanadium (V) is usually added, so it is also called Fe-Co-V soft magnetic alloy.
