PERMENDUR is an Iron-cobalt-vanadium soft magnetic alloy with high saturation magnetic induction strength. Among existing soft magnetic materials, this alloy has the highest saturation magnetic induction strength (2.4T), high Curie point (980℃) and the largest saturation magnetostrictive coefficient (60-100×10-6). Due to the high saturation magnetic induction strength, this kind of material can greatly reduce the volume when producing the same power motor. As an electromagnet, it can produce a large suction force in the same cross-sectional area. Due to the high Curie point, the alloy can work at higher temperatures where other soft magnetic materials have been completely demagnetized, and maintain good magnetic stability. Because of its large magnetostrictive coefficient, it is very suitable for magnetostrictive transducer with high output energy and high working efficiency. The alloy has low resistivity (0.27μΩ·m) and is not suitable for use at high frequency. The price is expensive, easy-to-oxidation, poor processing performance. If adding appropriate amount of nickel or other elements, can improve its processability.
