High saturation magnetic induction intensity Bs. Cobalt vanadium iron soft magnets has the highest saturation magnetic induction intensity (2.4T) in the existing soft magnetic alloys, the Curie point Tc is also very high, and the saturation magnetostriction coefficient is the largest, such as 1J22 can reach up to 60〜100×10-6. ⋆Low resistivity, high eddy current loss, not suitable for use at high frequency. Adding appropriate amount of Ni or V or other elements can improve its processability and oxidation performance, and most applications require coating protection. The main elements of cobalt vanadium iron soft magnets are metal cobalt, iron, etc., the price is relatively expensive, and the main technical characteristics are as follows, ⋆ The characteristics of high saturation magnetic induction intensity Bs make it possible to achieve miniaturization in the production of electromagnetic equipment of the same power. High Curie point Tc enables the alloy to maintain good magnetic stability at higher temperatures. Large magnetostriction coefficient is suitable for making transducers, which can greatly increase its output energy and efficiency. Components and assemblies made of cobalt vanadium iron alloy are widely used in fields that require miniaturization and high working temperature, such as aviation electrical appliances, micro-motors, electromagnets, relays, motors, etc. The main domestic grades are: 1J21, 1J22, 1J27 and so on.
